Hay Guys,
My oscar is sick. he just sits on the bottem of the tank and even lays on his sides. he is breathing very heavily and is not defending himself if other fish pick on on him ( Kribs, Firemouths ) He is a softy. he hasnt eatin in 2 days and ive had him for a week. he was very active when he was in there the first 4 days. i got him from the same shop i did last time and the last 1 i got died from the same thing.( im not going back there ). i tested my water and everything is fine and all my other fish are doing great.
what should i do

do i have to put him down
