Usually when I wake up and when I get home from work he/she <im going to assume my oscar is a he as I proceed> gets all excited and swims to top of tank shaking its tail real fast. His colors never dulled either till recently, hes the only fish in a 29 gallon aquarium (which I know is a bit small, but when I moved I sold my 180gallon and gave my 55 gallon to my dad). Hes only about 5 inches long though so I dont think the tank size is an issue yet. Recently though he has just been hanging out at the botttom of tank and not eating, his colors are not as bright either, they brighten up a little when I come to the tank to check on him. Ive treated the tank for Ick, going to purchase some meds for HITH after work and do a water change when I get home from work tonight. Other then that I'm at a lost I really like this fish hes got a lot of personality and dont want to lose him, any help would be appreciated. Thanks in advance for any replies, and good luck all you fish people out there.
