I've had my orange oranda for about four years. recently he has been sitting on the bottom a lot. It seems when he tries to swim he sinks head first. His head is quite large and his hood covers some of his eyes, so when he goes after his food he dives right into the bottom of the tank. I am not sure if he is diving to the bottom or the size of his head is pulling him down head first. Has anyone had this problem or know what might be wrong?
He is in a 75g tank with three other gold fish, half his size.
