The cichlid world is full of contradictions.
Some that look alike are the same species, some that look alike aren't
Take Chuco intermedia

The ones above and below are the same species, just from different river systems (not that far apart)
Different colors, and even slightly different body shape.

But the fish below are two different species

Above Herichthys carpintus, yet below H tamasopoensus

Another similar type look alike from Madagascar but separate species

Paratilapia polleni above, Paratilapia andapa below
