Leporinus: Latin, lepus, leporis = rabbit
Leporinus affinis is a strange fish, they are very intolerant of their own species and intruders in to their territory. My own fish would attack any new tank mate but the same species which was already established in the tank would be left alone. When new additions were planned the whole tank had to be rearranged and this prevented any problems. Once the new fish had been there for a couple of days it would be left completely alone. All leporinus are fast agile fish and need a lot of swimming space for them to behave naturally. They are also well known for jumping so it is essential that they are kept well covered. Some individuals will regard small fish as food while others will leave them alone.
Leporinus affinis is a herbivore in nature feeding on fruit, leaves, plants and sometimes insects, but they are known to take small fish occasionally. In captivity they are relatively easy to feed with algae based flake or pellet food, algae, tender cuttings off aquatic plants and the occasional blood worms.
There are no external differences between the sexes and so this species cannot be reliably sexed by looking at them.
Leporinus affinis has never been bred in captivity.
