Hous ing: Betta schalleri can be housed in pairs, species tanks, and community tanks. Pairs can be housed in
a 10 gallon tank, groups should be housed in a 30 gallon tank or larger. Pairs should be given cover such as
caves and plants. In a pair or species situation it is possible that fry could be discovered in the tanks. For best
results remove a brooding male.
Water Conditions: Not critical, schalleri is very tolerant of water chemistry and thrives in almost any type
of water as long as it is clean and well filtered. They should be kept at cool to mid 70s F.
Sexing: Males have a broader head then females and have a caudal spike typical of pugnax complex and
longer pelvic fins. Females ovaries might be visible via spotlighting.
Reproduction: Schalleri is a paternal mouthbrooder and the male incubates from 8 to 10 days. Incubation
time can vary with water temperature. Females normally initiate spawning.
Similar Species: Similar species would be pugnax complex members. Identification: ?

-change-color
I f you bought your go ld f i sh fo r i t s
colour, you may be di sappointed.
Goldfish are a common household pet.
Although less popular than dogs or cats, fish come in a close third because they are relatively easy to care for
and don't require a lot of attention, space, exercise or training.
Because they don't leave their aquarium, they don't create a mass of housework, and they are
also allergy-friendly for people who can't have a hairy pet.
However, something unusual can happen to goldfish. Over time, you may notice a change of colour.
The most common change in color is from gold to white, although other changes can occur as well. Read on
to learn what may be causing the change.
Goldfish, like koi, are a type of carp. And just like wild carp, wild
goldfish are usually olive green. Red, black, orange, white, yellow and
brown goldfish have all been created through selective breeding.
Because of the selective breeding process as well as environmental
factors, it's not uncommon for a goldfish to change colour. The change
can be to a similar color, a different shade or even a pattern.
Goldfish were one of the first domesticated fish. However, they did
not always have the bright orange and red scales that we are familiar with today.
There are plenty of reasons that goldfish can change colour. Here are a few
of them:
Change in environment. * Change in water type.
Water temperature. * Amount of light.
Introduction of other fish or goldfish into the aquarium.
Newborn transitioning into adult colouration. * Old age.
Goldfish have pigment in their skin that reacts to light. When their skin is deprived of light or they have
less exposure, this impacts on their skin. Over time, they can lose their colour
and turn white.
Think of it this way: When people go outside a lot, they get a tan.
If instead, they stay inside, they become paler. Sunlight works in a similar
way on goldfish.

Bichir Care and Breeding Guide
www.theaquariumguide.com/articles/bichir By Adam Edmond
Bichir fish is a family of fresh water fishes with ray fins that are native to the continent of Africa where
they are well spread out in different parts. There are up to 14 genuses of the fish that are known currently all
of which are evenly spread out in Africa. The fish are known to inhabit freshwater basins in Africa and parts of
the Indian sub-continent. The fish in the wild prefers muddy water with a bottom that is silted but sometimes
it even lives in bogs.
There are just various species of bichir that will survive in tank conditions such as the ornate bichir,
Senegal bichir, barred bichir, and marbled bichir. The fish has rather poor eyesight but a very strong sense of
smell that it uses to navigate the waters that it inhabits in the wild.
Appearance of Bichir Fish: The body of the fish is long looking almost similar to that of an eel and it has
unique dorsal finlets. The scales of the fish are diamond shaped and a close look at them reveals to you that
they are flexibly joined together. The body of the fish is very strong and it is interesting that the fish can still
breathe even when out of the water.
Keeping the fish in tank: Keeping Bichir in a tank is not complicated and even an aquarium beginner can
still set up a tank for keeping the fish successfully. The species of this fish are not demanding at all and as long
as the basic tank conditions are maintained it will just do well in captivity. Even in the wild the fish
are capable of inhabiting muddy dirty water due to their enduring nature. It must be noted that the fish is a
predator and if you wish to keep it in a community tank better keep it with large fish.
Another thing to keep in mind if you are planning to keep the fish in a community tank with other
fishes is that it is rather slow in finding it food. This means that if it is housed together with other fish that are
fast and swift at eating available food, it might find difficulty feeding well. This therefore calls on the aquarist
to be keen when administering food to the fish when in a community tank. Ensure that the fish has sufficient
food and is not left starving.
T a n k r e q u i r e m e n t s : Because the fish can grow to be very large it best to give them a big enough tank
that will give them ample space for
swimming. To keep one Bichir therefore,
you will need to have a tank that is at
least 50 gallons or even larger.
London Aquaria Society 6
Bichir Care and Breeding Guide
cont’d from page 5
Here below are some important tips for
keeping the successfully in a tank: Please ensure
that the tank has a lid to prevent the fish from
jumping out of the tank. It is notoriously known to
jump out of even large tanks.
The tank water pH should be 7 and for the
water hardness or softness the fish will just thrive in
both.
You can use a variety of tank decorations
which may include rocks and aquatic plants. The rocks will provide cave-like structures where the fish
can hide.
Bichir is a bottom dweller and feeder therefore the substrate should be chosen with care. A great choice can be
a thin layer of sand that will be easy to clean when need arises although you can as well use small-grained
gravel.
As you choose the stones to use for decoration in the tank, it is best to choose those that are smooth. You
can also use ceramics although these will not give a natural look that impresses so many people.
For filtration purposes it is best to installation a powerful canister filter that will be capable of use both
biological and mechanical filtration. This filter will help with keeping the water clean from the protein leftovers
that can quickly make the water highly toxic for the fish.
Feeding: Bichir is a predatory fish that should be fed on live foods which includes; bloodworms, calamari,
frozen shrimp, meat, and earthworm. You can as well give the fish artificial food such as fish flakes and pellet
food but it must be noted that his kind of food is not natural for the fish.
It is a slow feeder that will require lots of patience from the person that is offering food to it. It is best to lower
in small portions of food in the tank and wait for the fish to feed before offering more food. This will help to
ensure that fish doesn’t leave much of food that will serve as leftover to make the tank water toxic.
Compatibility with other fish in the tank: The fish will live well with many other fish species so long as
the fish you put in there are large enough not to be easily consumed by it. Bichir are not known to attack large
fish that are not aggressive to them. It would be best to choose fishes that are of the same size as Bichir to be
the tankmate. Some good examples of ideal tankmates can be blood parrot, Oscar, green terror, etc.
Sexing: There isn’t quite of a distinctive difference of the sexes although there are some slight differences. The
males have wider and thicker anal and dorsal fins but the females are generally wider in their genera size.
Breeding: Bichir is quite difficult to breed in home aquarium and most of the fish you find in pet shops were
most probably captured in the wild and put in tanks for sale. There is no categorical explanation of the process
of breeding the fish in home aquariums because most aquarists who have attempted this have had little success
if any. This therefore means that if you need to have more of them you may need to get one from the pet
store.

10 Of The Ugl ies t Fish In The World
The underwater world is filled with thousands of extraordinary
species that delight divers and swimmers from all around the world. You can
find creatures of all sizes, weights, shapes and colors, but some may seem strange
or even hideous. Let's review those that we consider the 10 ugliest fish in the world.
What is the ugliest f ish in the world ? The Blobfish was voted the ugliest f ish in the world by
the "Ugly Animals Preservation Society", and for you, who is the ugliest?
B lobf ish: This ugly fish, 30 cm long, made up of a gelatinous mass,
is only found in the abyss between 600 and 1200 meters deep.
Therefore, you won't be able to meet this horrible fish while
scuba diving. Its strange appearance comes from the pressure of
the depths, a hundred times greater than in the surface. Its
anatomy allows it to float without having to spend energy while
swimming. The best known photos of blobfish are not really
representative of its original form. Indeed, the fish returned from
the depths to the surface, undergoes a very strong decompression which profoundly modifies
its appearance giving it a crushed appearance.
Wolf fish: This very curious fish has an elongated body similar to the one of
moray eels. Its size can reach about 1 meter 50 for a weight of 18 kg. His
chubby head, cat eyes, thick lips and prominent canines give him a
somewhat monstrous appearance. Whether blue or olive green, this fish is a real
curiosity for divers.
Spotted handf ish : This fish does not swim but walk with its two little legs. It
measures up to 15 cm long. It lives in the southwest of the Pacific Ocean and are
endemic to Tasmania and Australia. They are threatened of extinction since
the accidental introduction of a species of starfish (Asterias amurensis) that feeds on
their eggs.
Humpback anglerfish: This underwater monster lives on the sea floor between
1000 and 3000 meters. The male is much smaller than the female (3 cm
against 20 cm). He has on the head an organ that emits light and which serves both
to trap its prey but also to seduce a female. To breed, the male clings to the female
and then merges with it.
Sea Pig: This strange creature of the abyss living between 6000 and 9500 meters
deep, is characterized by a swollen body, pale pink, translucent, 7 pairs of large
feet and 4 long dorsal papillae. This species also called "sea pig" feeds on the
upper layer of sediments resting on the bottom. These poor creatures are
sometimes parasitized by other organisms such as gastropods or crustaceans.
London Aquaria Society 8
10 Of The Ugliest Fish In The World
cont’d from page 7Wo
Uranoscopidae: This fish, with its flattened body and big head is
really scary. Measuring 20 to 90 cm, the uranoscopidae burrows
into the sand to surprise its prey. Some species even have a
crescent-shaped bait located on the floor of the mouth, which they
agitate to make believe that it is a worm. Be careful where you lay
your hands as these fish are very venomous, with thorns behind the
operculum and above the pectoral fins. Species such as Astroscopus
also cause electrical shock to their victim.
Smooth lumpfish: Living in cold waters, this fish is a poor swimmer
because of its tiny fins. Specimens of all sizes and shapes can be found. Some
species are very cute (Eumicrotremus phrynoides) and others particularly ugly
(Aptocyclus ventr icosus). Most photos on the internet show a
misshapen body due to the barautromatisms received during the ascent on
the boat. Icelandic fishermen caught specimens of nearly 2 tons.
Ocean sunfish: Straight out of a Japanese manga, this big bony fish
has a very strange prominent head that covers a large part of his body.
Very popular with underwater divers, the moon fish leaves no
one indifferent. The Mola Mola is the world's heaviest bonefish (one ton
on average) and has a wingspan of up to 3 meters for over 2 tonnes.
Opinions are divided on its aspect: some regard it as beautiful and
majestic, others, on the contrary, consider it ugly and awkward.
Toadfish: This fish of about 30cm is also called "hideous toadfish". He
can live in harsh conditions and needs little food. To catch its prey
(mollusks, crustaceans, small fish), the toadfish hides in the sand and arises
at the right time. During the season of the loves, the male uses his horns
positioned on the top of his head to seduce the female. The female enters
the nest, lays eggs, then leaves. The male fertilizes the eggs that hatch
about a month later.
The striated frogfish or hairy frogfish : This small (up to 22 cm
long) fish is predominantly found in the tropical and subtropical waters of
the Indian Ocean, Pacific Ocean and even the Atlantic Ocean. Its body is
globular, extensible and its skin is covered with small thorns that resemble
long hairs. His large mouth allows him to swallow prey as big as him. It is
a voracious carnivore that gobbles all the preys that pass within its reach.
The coloring of the Frog-Frog adapts to the shades of the environment in
which it lives. It can change colors in a few weeks. Finally, after mating,
the male can kill or eat the female if it stays too long in the vicinity.

terrestrial-snails/ariophantidae-black-faced-snails/platymma-
tweediei-fire-snail/
From the cloud forest of Cameron Highlands, the beautiful and mystical Platymma tweediei, the largest
endemic snail from the Peninsula Malaysia (arguably the bertia brookei from Borneo is larger). It is also known
as the Fire snail for its beautiful red foot. It is also being studied as the density of the population is said to be
only 100 km radius and it was intensely collected as pets due to its beauty, but it is one species that is
very difficult to keep alive as it lives in very cool and humid temperatures (in Europe it is cool but it
is not humid (the humidity in Tanah Rata is 79%!), thus causing it to die quickly). It is found in more
than 1000m above sea level, never lower. It may be protected in the future. This snail is made up of very
little calcium, but thick robust silky black periostracum which is very unique. A real collectors’
item for the terrestrial snail collector!

Ember Tetra
https://www.liveaquaria.com/product/3511/?pcatid=3511
The Ember Tetra is a peaceful, schooling fish that originates from the Araguaia River basin. This beautiful
reddish/orange fish is mildly translucent near its pelvic fin. The Ember Tetra’s eyes are the same color as the
fish, outlined in black and is a great fish for the community aquarium.
Hiding spaces such as rocks, plants, and driftwood are recommended to give this fish a sense of security.
Taller plants should be used to coincide with its mid-level swimming habits along with plenty of rock formed
cave structures.
Ember Tetras will breed occasionally in an aquarium setting and a hospital or "breeding tank" will be
necessary. Slightly acidic water is best for optimal breeding habits. After the eggs have been fertilized, removing
the parents will be necessary to reduce the number of lost fry. Feed the fry baby brine shrimp or crushed flake
food.
The Ember Tetra
will accept many small
foods such as brine
shrimp or daphnia,
freeze-dried bloodworms
and tubifex, micro pellet
food, and a high quality
flake food.

Aquarium Fish That Will Eat Planaria
www.cuteness.com/article/aquarium-fish-eat-planaria By: Hikari Loftus
Planaria are small, white flatworms that thrive in aquariums that have not been cleaned properly. Many
freshwater fish enjoy eating these worms. Although the worms are not harmful to the fish, the conditions in
which they thrive can be fatal. Planaria can even get into the gills of fish, causing irritation. While filling your
tank with Planaria-eating fish can take care of a few worms, the overall conditions that allow Planaria to grow
must be treated so no harm will come to the fish.
Aquarium Fish That Will Eat Planaria : Josh Davis, President of Live Fish Direct, says that the following
fish are known to eat Planaria, although he asserts that almost any fish will eat them: angel fish,
fat heads, gambusia, orangethroat darters, redbelly dace, sand shiner, central stoneroller, freshwater blue and
pearl gouramis, guppies, goldfish, common blowfish, mollies, tiger barbs, betta fish, pelvicachromis pulcher and
paradise fish.
Planar ia: Planaria thrive in freshwater aquariums that are not properly cleaned or contain lots of excess
food at the bottom. While Planaria are not dangerous to the fish, the conditions that allow Planaria to thrive
can be fatal to the fish with long-term exposure. As excess fish food decomposes, it releases ammonia into the
water, which can also cause a rise in nitrate levels.
Removing Planar ia : Although fish eat Planaria, relying on them is not an effective way to remove the
worms. Planaria will also feed on fish eggs, and should be removed for fish breeding. If the aquarium is not
cleaned properly, the fish will eventually die from toxins in the water that have allowed the Planaria to grow.
Begin by removing the excess food the Planaria feed on by partially changing the water and vacuuming the
gravel in the tank. You may also stir the gravel daily until the excess waste is removed through the
filtration system in addition to the weekly partial water changes, until the aquarium is clean. Using products
that keep high levels of beneficial bacteria will combat high levels of ammonia and keep aquariums healthy.
Proper Fish Feeding : In order to prevent ideal Planaria growing conditions in aquariums, feed your fish
properly to avoid excess food in the tank. Feed fish only as much as they can eat in five minutes. Remove all
uneaten food after 10 minutes. Feeding fish floating food keeps the food from sinking into the gravel and
makes removal easier. Generally, fish need only be fed once or twice a day unless otherwise directed
for certain species.

Planaria and Shrimp
I s P lana r ia bad for shr imp? : February 23, 2020 Brown, black and white planaria are dangerous,
but each in their own way. White planaria are aggressive predators and are particularly dangerous to
shr imp.... While brown and black planaria do not hunt shr imp, they are more than capable of killing
them. You see, p l anar i a move on a slime trail, just like snails.
Can P lana r ia k i l l sh r imp? For shr imp breeders, p lanar ia can become a disaster. The point is that
they definitely k i l l shr imp and snails. ... When they find their way into the shr imp, they wi l l eat it alive.
While planaria may not harm fish, if you're a shrimp keeper, planaria may prove to be more of a
headache. Some of these flatworm species are predators that prey on anything small that comes their way,
including eggs, shrimplets, other worms, and sometimes even adult s h r imp .

Both species of Siamese Tiger Fish have protrusile mouths which are used to take large prey and both
species cannot be sexed visually. Although Siamese Tiger Fish are sometimes described as being a
brackish water species; they are a true freshwater fish that thrives in clean alkaline water conditions.
Siamese Tiger Fish should be housed with other peaceful species of their own size, or with at least 5 or
more of their own species in a densely planted, 100 gallon or larger aquarium, with a sandy or fine gravel
substrate decorated with driftwood branches or twigs that can provide the fish with places to hide.
They prefer a dimly lit tank with plenty of swimming space, and because they are extremely sensitive to
pollutants, they must have excellent water quality and regular water changes in order to thrive.
No captive breeding has yet been accomplished with this species and virtually no information about
their breeding habits exist.
Siamese Tiger Fish are predatory carnivores that eat live fish in their natural habitat. In an aquarium
environment they can be taught to eat dead meaty foods such as shrimp, prawn, mussels, white baits, and for
juveniles; bloodworms and brine shrimp.
S i amese T iger F i sh are rare in the t ropical f i sh keeping hobby and when avai lable

20 Facts About Leptocephalus, To Know What This Creature Is
www.science-rumors.com/author/a0952223536
2018-11-02Alisa Su
Among the many animals that are strange and rare,
the Leptocephalus occupies a unique for being the larvae of a
group of eels which was earlier considered to be a separate
species of eel. Unlike most other larvae, the Leptocephalus
grows big and has a very long larval stage.
(1) Leptocephalus is the name given to the larvae of many
of the common eel varieties and other creatures of the super -order
Elopomorph including the common eels like Conger, Moray Eel and
Garden Eel. The name means “slim head”.
(2) This was earlier considered to be a separate species before being
recognized as the larvae of these eels. They are believed to have been in
existence for over 140 million years.
(3) The Leptocephali can be the larvae of both marine and freshwater eels.
The larvae of the freshwater eels move to the fresh waters as they start
metamorphizing.
(4) There are some species of eels that lay eggs far away from their homes. The Leptocephali of these eels use
the ocean current to move back to the continent where the parents came from, before metamorphizing into
adults.
(5) The Leptocephali of certain species of European eels migrate through
the North Atlantic Ocean, taking anywhere between 1.5 to 2.5 years to
complete the journey.
(6) Leptocephalus metamorphizes into one stage after other. They turn into
Glass Eels which are transparent, then into Elvers which start to
gain pigmentation and then Juvenile Eels which are also known as yellow
eels.
(7) Before they metamorphize into the next stage of glass eels, they travel
from the ocean to the intertidal region.
(8) They have flat bodies with a thin layer of
muscles and small organs which make them appear
transparent.
(9) The Leptocephali have dorsal and anal fins.
They don’t have pelvic fins.
(10) What makes them different from other larvae is
that they grow much bigger and have a longer
larval period of around three months to one year.

Windsor: The Windsor Aquarium Society June meeting was a social meeting where we were able to talk
about our bus trip to the Toronto area the week before and we let everyone know how all our new fish were
doing.
We had our bowl show on old world cichlids and we watched a small clip on next month’s speaker
Lucas Brett's YouTube channel. It was another great meeting for the Windsor Aquarium Society
Tom Mason fielded questions in regards to hosting the Convention next year. We will have 6 Speakers
talking on rainbow topics.
Leo O’Reilly from Australia, Gary Lange, Hans Georg Evers, Wim Heemskerk from the Netherlands,
John Seyjagat and Tim McCaskie.
Tom advised that posters will be in English and French. We need someone to run the Show and we
also need to be more aware of proper housing of fish.
We will have our Annual Meeting on Sunday morning, May 1st - 3rd, 2020, a venue is yet to be
determined. Vendor tables will also be there. Adjourned at 2:37 by Ed.

What do you want to read? The intent of this newsletter is to share some of the details of the meeting and
upcoming events. From time to time, I try to include recent news. If there is something you would like to see,
or if you have an article you would like included, please send it to me, [email protected] .
Meetings: Who can attend? Any member of an Aquarium Club can attend the General Meeting that follows
the Executive Meeting. It usually starts around 12:00 noon.
Why should you attend? To be part of the discussion that takes place between other clubs and items that
are raised by the Executive. It’s a great way to share ideas and discuss issues you may be having.
Unable to attend, contact [email protected] for instructions.
What is CAOAC? We are often asked this question. CAOAC stands for The Canadian Association of Aquarium
Clubs. We are a non-profit corporation and are composed of Members aquariums, reptile & amphibian, pond &
water garden and similar clubs or Societies from across Canada and the Northeast United States. CAOAC was
founded in 1959 (incorporated in 1963) to allow the clubs to work together for their common good and the
good of the hobby.
Legislative issues, promotion of events, a judging system, national awards, assistance for new
clubs, & liability Insurance are just a few of the things on which clubs can work and benefit together. Recently, a
Fish Rescue Program has begun. This has been developed with outside partners who also have an interest in our
hobby and environmental issues.
20 Facts About Leptocephalus, To Know What This Creature Is
cont’d from page 15
(11) They don’t have red blood cells till they start
metamorphizing into the glass eel stage.
(12) They don’t seem to eat zooplanktons like other fish
larvae do. They seem to live on the floating particles on
sea known as marine snow.
(13) They seem to prefer darkness as they live deeper
during the day and at around 100 mts deep during the
night.
(14) Another specialty of Leptocephali is that they are
found almost all over the world. They occur in all
climates of the world.
(15) There is a stage before the Leptocephalus stage and after the egg stage when it feeds solely on the egg yolk.
The larvae continue to grow even after it stops feeding on egg yolk.
(16) The Leptocephalus larvae have long pointed teeth at first which turn into short teeth with an increase in the
number of teeth.
(17) Some family of the Leptocephalus have telescopic eyes with a tube and a spherical lens on top of it.
(18) The Leptocephalus are still not fully understood as they don’t feed on planktons. This makes it difficult for
them to be caught in the plankton nets for scientists to study them.
(19) The Leptocephali are as used as foods in some countries like Japan. They are served raw. The Japanese eat
them after dipping in Tosazu mixes with vinegar.
(20) Leptocephali is harmful to humans. It can be accidentally consumed along with drinking water and can
cause health problems. It is better to always boil the tap water before drinking.

PEACEFUL BETTA (Betta Imbellis)
https://aquaristsacrosscanada.com/products/peaceful-betta
This species fares best in a well-planted, shady aquarium with
plenty of surface cover in the form of tall stem plants, floating
types such as Salvinia or Riccia spp., or tropical lilies from the
genus Nymphaea. Cryptocoryne spp. are also a good choice.
Driftwood can also be used and other plants such
as Microsorum or Taxiphyllum spp. may be attached to it. Small clay
plant pots, lengths of plastic piping or empty camera film cases can also be included to provide further shelter.
The addition of dried leaf litter offers additional cover and brings with it the growth of microbe colonies
as decomposition occurs. These can provide a valuable secondary food source for fry, while tannins and other
chemicals released by the decaying leaves are
considered beneficial.
As i t natural ly inhabit s s luggi sh
environments strong water movement should be
avoided, with an air-powered sponge filter set
to turn over gently adequate. Keep
the aquarium well-covered and do not fill it to
the top since like all Betta spp. it requires
occasional access to the layer of humid air that
will form above the water surface, and is
an excellent jumper.
