Mine was not this bad but it was smashed bad enough that he could not eat. I still think it will be ok. I wouldn't worry about it not eating. I am training mine onto pellets now and he goes 7-14 days between eating until I break down and give him shrimp. I would try to upgrade the tank asap. Mine was banging himself bad at 9-10" in a 125 and I will probably move him from his 240 into a bigger tank soon. As long as no fungus or infection sets in I would still not treat with meds. They are an extremely fast healing fish. Good luck and keep us updated.
