Bulldog pleco - Chaetostoma milesi https://en.aqua-fish.net/fish/bulldog-pleco Bulldog pleco: Chaetostoma milesi Recommended temperature: 23 - 25 °C (73.4 - 77°F) Scientific name: Chaetostoma milesi The way how these fish reproduce: Spawning Common name: Bulldog pleco Where the species comes from: South America Family: Loricariidae Temperament to its own species: peaceful Usual size in fish tanks: 10 - 13 cm (3.94 - 5.12 inch) Temperament toward other fish species: peaceful Recommended pH range for the specie s: 6 - 8 Recommended water hardness (dGH) : 5 - 19°N (89.29 - 339.29ppm) Food and feeding: Feed Bulldog pleco’s algae wafers, and include in their diet vegetable matter like cucumber, romaine lettuce and zucchini. They will accept a weekly treat of bloodworms. Origin: South America; Bulldog pleco’s are mainly to be found in the Magdalena Basin, Colombia. Sexing: Males will have a larger head but a slimmer profile than the females. Their pelvic fins will also be slightly larger. Breeding: As of yet there are no reported cases of Chaetostoma milesi breeding in the aquarium. It is believed that this is due to requiring a lot of flowing water. Lifespan: Expected life span for Bulldog pleco is 12 years. Short description: This pleco can be a very timid fish, when the lights are out it will turn into a very effective tank cleaner, eating all the algae that it comes across. It is a very peaceful species, there should be no problem introducing this fish into a community aquarium, but it will require hiding places for the daytime.

We will also be having our monthly Mini Auction, so please bring in any extra fish, plants or other items you might have. The CAOAC convention will be on the first weekend in May, instead of the long weekend this year. More information will be coming. Don’t forget, we are meeting at a new location this year, Aberdeen Public School on Grey Street. Remember our veterans this month, thank them for their service when you see them and keep the memories alive in your individual ways. Rick Hodgins President London Aquaria Society Interesting Facts About Crayfish Author and Website unknown. Hot Tempered: Crayfish are hot tempered little things. (Crayfish owners probably know this.) They are known for eating other crayfish tank buddies and the moms are known for often eating their smaller offspring. (Wow! They should be arrested and prosecuted.) Yeah, pretty crazy. – But these are just the not so awesome, but interesting facts about crayfish. The other crayfish that get eaten are usually molting. And when they are in the process of molting they become much more susceptible to an attack because they are soft. A very, very aggressive type of crayfish is the Pacifastacus leniusculus. “I’ve seen entire little juveniles – whole – in the gut contents of adults! Molting represents a huge tradeoff for any arthropod because it requires being ‘soft’ in your new exoskeleton until it hardens up again… If you’ve ever had ‘soft shelled’ crab in a sushi restaurant, you know what I mean. For aggressive animals like crayfish, ‘deciding’ when to molt is tricky. Your conspecifics can prey directly on you very easily when you are soft, but in the long run, if you can manage to become a very large individual (lots of molts later), you can become the bully on the block!” says Carin Anne Bondar, Ph.D , a crayfish expert and Vancouver-based biologist. What???: Some other crazy facts about crayfish. Did you know that worms live in crayfish pinchers? – And they actually urinate to solicit mating? You would think that the urination thing would actually deter mating, but I guess this is what the lady crayfish are looking for in a crayfish partner these days. London Aquaria Society 3 Vietnam cafe where fish swim around diners accused of animal cruelty Kayla Wong | https://mothership.sg/2019/05/vietnam-fish-cafe-cruel/ You’ve heard of fish spas in Singapore, where you could soak your feet in a tank while live fish nip at your heels. A restaurant in Ho Chi Minh City, Vietnam, took it a step further and allowed fish to swim around the feet of customers as they dine. However, it was forced to change the concept after it received complaints of animal cruelty. The cafe went viral back in late 2018 for its unique concept of allowing fish to swim around the diners in shallow waters on the floor. Pictures of the dining establishment recently surfaced on the internet again on the travel Facebook page, Travel Hit List. The pictures were mostly taken from a cafe called Amix Coffee. According to Oddity Central, the cafe had two floors that were flooded up to around 25 centimetres, and fishes swam freely in the waters. The floors were insulated with two layers of plastic tarp and furniture legs were wrapped in cotton to prevent damage to the tarp. The waters were kept clean using a triple filtration system. Before entering the cafe, customers have to take off their shoes and clean their feet. The owner, 23-year-old Nguyen Duoc Hoa, told Spanish news agency Agencia EFE that he wanted to create a unique concept that did not exist in any other place and since he is from a coastal city and loves fishes, he thought it was a good way to create a business that combines innovation and his hobby. Changed concept after complaints of animal cruelty However, barely a few months after the cafe introduced the concept to the public, it was accused of animal abuse. Critics said the fishes were in a stressful environment, as children chased after them at times, despite the rules forbidding them to do so. In a previous interview with Agencia EFE, Hoa said that while most families “don’t cause any problems”, there have been some “naughty children who try to catch the fish, and their parents don’t say anything”. When that happened, he had to ask them to leave. Malaysian Chinese-language news agency Sin Chew Daily even claimed some fish had been trampled to death by customers. The cafe has since changed its concept, removing the fishes from the floors and placing them in clear tanks that are placed around the cafe instead. This resulted in some disappointment for tourists who visited the cafe in hopes of dipping their feet in the fish filled waters. You can watch some videos of the cafe when customers could still have close contact with Thanks Annette the fish here and here: London Aquaria Society 4 Benthochromis tricoti https://www.cichlid-forum.com/profiles/species.php?id=1482 Scientific Name: Benthochromis tricoti Temperament: Mildly Aggressive Pronunciation: b n-th -kr -m s tr -k -t Conspecific Temperament: Mildly Aggressive Geo. Origin: Lake Tanganyika Maximum Size: 10" Habitat: Open Water Temperature: 77 - 79°F Diet: Carnivore pH: 8.6 Gender Differences: Dimorphic Water Hardness: Very Hard Breeding: Maternal Mouthbrooder Difficulty: 4 Comments: A large, beautiful and graceful cichlid, this fish is best in aquariums of 125 gallons or larger. It is also best with other calm cichlids, as females have a tendency to not carry to term when the tank is too hectic for their liking. The perfect tankmates are Paracyprichromis, Lestradea and Ectodus. In the wild, they feed on free swimming copepods and plankton. A diet including mysis, cyclops, krill, plankton and flake is recommended. As a shoaling fish, it is suggested to keep at least six, and preferrably more of this fish to see it at its best behaviour.
