I have 3 x 4" Leopard Ctenopomas Mine are now eating live fish, raw fish strips and earth worms. The eat like pigs everyday. Mine almost choke, they go after the food the 5" thin bar dats eats. I have two of them in with the Dats and they are with the bid 9" Dat. They all get along great.
One thing I noticed as they got bigger, their face started gettign a "Green" tint. I have never seem them with greenish tinted scales on the face before. But these guys seem to grow fast. I've had mine about 7 months and when I got them they were about 1" now they are pretty big being what they are and all.
