So i was given two rather large Goldfish by a friend and in the tank i had 2 Cory cats, the largest of the good fish ate one of them. I have since removed the other two. But now it is hanging from its mouth and has been all day, will this just work it self out. I don't want it to die. I also have a bunch of African Cichlids in another tank. This is just the first time i have seen this big Goldfish eat another fish.
