America. Many species have been hybridized through the use of hormones in an effort to get even larger fish. This same size factor also makes them very popular for sport fishing. Pimelodids are a common addition to Amazonian-themed exhibits in zoos and public aquaria. Despite the looming danger of size in many species, pimelodids remain a popular home aquarium fish. Controversy exists over whether or not many of the larger species should be sold in the hobby because of their adult size. Also, some disagreement occurs over hybrids appearing in the hobby, as well. Many species are hardy and easy to take care of. However, care should have course be taken on what other fish to house pimelodids with, as they do not hesitate to eat other fish that are small enough.
