Fresh Water Fish Group - Tooth Carps

Most live bearing fish are included in this group. However, some are egg-laying as well. In general, these fish have narrow bodies and flat topped heads. This fish group includes platies, guppies, and mollies.

Fresh Water Fish Group - Cichlids

Cichlids are some of the most colorful of the freshwater fish kept in home aquariums. Many cichlids are wide bodied such as discus and angel fish. There are both South American and African cichlids.
