swervo513;4367802; said:i would look for a fish that is dominant and one that is submissive. cichlids will often change sex to fit their roles.
that one surprised me too . . .
did see some references on-line to certain African cichlids - - mbuna species - - where dominant females may take on the gender roles of the male, for example when there are no males in the tank. they look and act like males, but they do not literally change sex . . . and this doesn't apply to convicts
the OP's problem is just that the convicts he is trying to sex may be too juvenile to sex properly at this point
