I have a male and female texas cichlid for about 3 months now,the thing is the female has grown from 1 1/2 to almost 4 in and the male is the same as when i first brought him home at 2 in.I have both in a 55 gallon.she does not pick on him,but eats pellets,flakes and krill he on the other hand only eats the krill.Im thinking that at this rate, in time she will kill him.Is there anything i can do i was hoping to get a breeding pair out of them.
