The term ¨red devilï is sometimes a catch a term for those species of the genus Amphilophus , of Ncaraguuan great lake cichllids..
There are pehaps at least a dozen, but not all members of the genus Amphilophus are called , or lumped into the red devil catagory by discriminating cichlid keepers.
A trimaculatus would not usually thought of as a red devil, neither would A islanus, being from Mexico.
A hogaboomorum is from Honduras, and superficially resembles many banded red devils, but is not usually lumped into the red devil catagory
It would be more appropriate to use each species scienticic name, instead of cramming them into the common name =red devil ,
if accuracy is desired.


Left is Amphilophus flaveolus, right A amarillo
Below A trimaculatus


Left a male, right a female.
The thing is , most Amphilopus have within each species, the ability to havecolor morrphs that can suggest the term ¨red devil¨
but as you see above, are hardly red.
It´s that the red color morphs are sometimes most desired by aquarists.
I just happen to prefer the non red varieties
Most start out as juvies looking like the one below, before turning red
