Sarah, I think the fish in the avatar above is a Parrot Cichlid (the SA parrot, not the hybrid). Could be wrong. And BTW, for a single Jag a 75 would do. Of course a 125 or 150 would be better, but not absolutely necessary. I used to breed my pair in a 55 when the male was 9" and the female was 6". No problem.
GLHF!
