Rheoheros coeruleus
Rheoheros coeruleus is a species of cichlid fish endemic to the Atlantic‑slope drainages of Chiapas, Mexico and adjacent Guatemala. It is a rheophilic member of the tribe Heroini and one of two currently recognized species in the genus Rheoheros. The species was originally described as Theraps coeruleus by Ranier Stawikowski and Uwe Werner in 1987, based on material from fast‑flowing tributaries of the Río Grijalva–Usumacinta system.
