I recently picked up a 14" jaguar cichlid that has whole in the head. He wasn't getting a very good diet. Mostly bloodworms and pinkies. I can't get him to eat anything. Tried almost every pellet on the market. Shrimp, tilapia, and mysis shrimp. He just refuses to eat anything and it's been over a week. Any suggestions? His hole in the head is starting to get worse so I need to get him eating quick.
