Heres a wierd thing, got 2 small Oscars 2 inches, one of them keeps passing a sort of pellet of white worms which scatter all around the tank and end up clinging to the glass. He looks healthy enough and eats like all Oscars eat. Any ideas anyone?

This is why I stated I have never heard of them being passed as a pellet.Headrush;1519595; said:He described them coming out of this fish, these are not planaria. Planaria are a result of high organics (too much waste) in the tank, I've had them before too, They are not a threat to the health of the fish.
IMO what he described are tapeworms, or some other parasitic organism....which ARE a threat to his fish.
Shouldn't be too tough to treat though. Also Be careful with your hands in the tank. I believe human can get tape worms if there is a cut or something on your hand and its in the tank.
Good luck with them![]()
