Are the black convict cichlids less aggressive than the pink convict cichlids?

Question

I have heard that the pinks are less aggressive but just wanted to know. I thought that they have the same aggressiveness?

Answer 1

when we used to have some the pink ones used to bite at and kill the black ones.

Answer 2

no, they are the same fish

Answer 3

Pink or black doesn't really matter.  It's just a color mutation, not a difference in species that dictates behavior or aggression.  Every individual fish has its own personality, so one fish may be more or less aggressive than another.  It doesn't have anything to do with the color of the fish.  That's just coincidental.
