Goldfries, is there anything special that you feed them for color. I'm using the tetramin flakes w/ color enhancer right now along with cichlid sticks and pellets. I usually rotate with no specific pattern between the three and put flakes in at least once a day. Just wondering if there was a certain type of food that you preferred over the others. Does the size of the grow up tank really matter for coloration??? I've got one tiger oscar in a 29 gal tank with a 3-4" pleco and an african cichlid that is just a tiny bit smaller than the Oscar which is about 4in. long also.
PS. How big can I let the Oscar get before moving him to a larger tank I don't want him to feel crowded.
