Keeping Betta schalleri from an Aquarist View Housin g: 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: ? Original Citation: Ng, P. K. L. 1994. [68] Ng, P. K. L. 1994. [68]

Good day to all. I hope everyone is keeping healthy and safe!

Due to the uncertainty of the COVID-19 pandemic, the Executive of the London Aquaria Society have decided to cancel the meetings scheduled for May and June, as well as our Spring Auction, that was scheduled for May 31st. This is done, following the current guidelines set by our governments and health professionals. The uncertainty of when the restrictions will be lifted, made it necessary to plan ahead for the balance of this season and we are hoping to resume our meetings in September. Please watch our Facebook page and website for future updates in the coming months.

Please take care of yourselves and your families, so that we all stay safe and healthy throughout this ordeal. Check on your senior friends and neighbours to see if they are safe and healthy or in

need of anything, by means of a quick call, and show your appreciation to the health care workers and emergency response workers that are all dedicated to helping us stay healthy and safe. Thank you

Rick Hodgins President London Aquaria Society

Susannah Birch: Susannah's husband asked if he could have a fish. She didn't realize he meant plural. 8 big fish tanks later, she knows too much about fish. https://pethelpful.com/fish-aquariums/Why-do-goldfish -change-color If you bought your goldfish for its colour, you may be disappointed. Updated on May 25, 2019 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 Goldfish haven’t can be to a similar color, a different shade or even a pattern. always been orange. 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 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. Tank requirements : 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 5 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 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.

www.spotmydive.com/en/news/ugliest-fish-in-the-world 10 Of The Ugliest 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 fish in the world ? The Blobfish was voted the ugliest fish in the world by the "Ugly Preservation Society", and for you, who is the ugliest?

Blobfish: 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 handfish: 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.

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 ventricosus). 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.

Platymma Tweediei, also www.malacology-asia.com/index.php/product-category/ known as the Fire Snail 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!

Overview

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 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.

London Aquaria Society 10 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. Planaria: 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 Planaria: 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.

The Siamese Tiger Fish (Datnioides pulcher) is also referred to as Siamese Tiger Perch, Widebar Tigerfish, Widebar Datnoid, Gold Datnoid and Wide Bar Dat/Tigerfish by tropical fish keeping enthusiasts. Siamese Tiger Fish come from the Mekong and Chao Phraya basins of SouthEast Asia and are one of only three true freshwater species of DatnioidesNew Business

Siamese Tiger Fish are striking in appearance with 3 to 4 wide black vertical bands on their silver white to yellow flanks that distinguish them from False Siamese Tiger Fish (Datnioides microlepis) which have 5 to 7 vertical bands. Datnioides pulcher specimens collected from the lower Mekong have a 5th bar which is absent from those collected from the Chao Phraya basin. Sexual dimorphism is not known and no method has been devised to differentiate males from females.

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”. Club Reports (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.

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.

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 it naturally inhabits sluggish 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.
