Looks like a black acara(Cichlasoma bimaculatum).

Agree with those that suggest one of the genus Cichlasoma, AKA the acara types.
There are 13 species in the genus and many color morphs, which include bimaculatum, and the port.
Below is Cichlasoma dimerus to compare.

+1 for dimerus

Possible hybrid? Don't think that's a Mayan. Doesn't look anything like one. Take a look at mine.. Over 4"
