There is nothing of the natural colour left. This plus the young age makes it impossible to know which species this is or which were part in the making.

Even in their natural form, Tilapines are hard to ID, there are perhaps over 100 different species that are similar when juvies.
Yours look to me like the line-bred color varient of pink Coptodan (T) zillii
Here are a few in natural coloration.

and just a heads up, because you started the thread in S/Central American section, and although Tilapines have been introduced all over the Americas, and over the rest of the world, they are really Africans
