Hi, I have a sick Oscar, I've been feeding him fish food, crickets and worms.
He is now swollen to twice his size. He has not relieved himself in several days.
I think he is dying and I don't now what to do for him. Please help.
It sounds awful. Any chance he may have eaten something he shouldn't have?
Pictures would be helpful. And as smb said, if you can get him to eat some peas, they have a laxative effect on fish. It just might help.
Good luck!
