Pygmy are not the largest fish out there, but their small size is a big draw that many people cannot resist.
These are very well-behaved fish and will keep to themselves in a community setup. If a fight does break out, they are not the ones who started it. Fish of a similar size and gentle temperament are good choices. They will spend most of their time in the lower levels but swim in shoals higher up in the tank. Be aware of this so you do not overstock your tank with fish who want to spend their time in the mid-section. Shoaling is a rare occurrence for bottom-dwellers, but Pygmys need to be a part of a group with at least four but a recommended eight to be happy. They then also become an impressive sight to behold.
If you see Pygmys’ at the very top of your tank. They could be using their intestine to take in oxygen from the air and could be a sign of ill water quality. As Catfish, they will spend their time along a sandy substrate. Hiding among plants and “debris” such as sticks or sizeable forms of wood, also try rocks. Fine gravel or sandy substrates are the better options as Pygmy will then be less likely to injure themselves.
Pygmy are small fish, females 2cm long and males are even smaller at about 1.5cm. Their bodies are silver, a black line running from their snout to the tail fin. Breeding is not a difficult task. Mature Pygmy will not need any help here. But once you realise how small adult Pgymy are, you could imagine how tiny their fry are. This could be the real challenge of breeding Pygmy at home. Since their bodies are so small, they will need smaller food. Once spawning has occurred, remove adult fish from the tank as they try to eat their fry.
