fire mouth cichlid

you might be able to put 2 in a 20 long. if its a pair it might work but the male might pester the feamle if she doesnt wanna breed, or the female might pester the male if she has spawned. they also may be a bit cramped at full growth size.

ive only got one little one in a 55 but hes by far the most aggresive one of the fish in there.
