From WIKIPEDIA :
There are 15 known species of peacock bass and two more
ichthyologists have yet to name. Their common names vary greatly depending on the country, region, stage of development and local anglers. Below is a complete list of the
taxonomic,
binomial names for these cichlids, along with four English common names.

- Cichla intermedia (royal peacock bass)
- Cichla jariina
- Cichla kelberi
