I have a 16" oscar that has hith. Ive checked the water quality, and its perfect. Its in a 90 gal. tank with a drip set-up 1gal/hr and a 1400gph pump running imto a wet/dry for a 300 gal tank. The water is crystal clear. I try to feed it a varied diet, but the oscar will not eat pellets or ciclid stics. I dont know why? Ive been feeding it feeder fish, along with ciclid omni-vegi flake formula- this is mostly for the smaller ciclids, but the oscar also eats it. I also through night crtawlers in there, and grubs occasionally. I try to at least once a week. During the summer I put leaches in once in a while. I dont know if thats good or not, but the oscar loves them. My question is what am I doing wrong? , Also does this hith clear up completely when its healed, or will there always be those pits in his head? I also raised the water temp up to 80` and added salt. Any other sugestions?????
