I have a 12" oscar that spooks easily more and more. I wouldnt have a problem with this but he's damaging his head quit a bit when he darts aimlessly. Hes in a 125 Gal with other fish and is the largest by far. Water dimensions are perfect. Ive also noticed that it takes him quite a bit to get awake in the morning, just lays close bottom. when i do a morning feeding he wont eat until at least 10 am. All the other fish attack the food no mater the hour. any suggestions?
