I don't mind doing frequent water changes, I just want a huge *** jack dempsey fish when he get solder. Is it okay to feed him as much as he'll eat? i mix up the foods, brine shrimp, bloodworms, regular worms, pellet foods, and flakes. hes fat as hell and really dark and aggressive. IS there a problem getting him to fat? I have plants in the tank, live sand and a cascade 1500 (i think) filter filled with bio ceramic media.
