No, that was just the initial fight with the new guy going in, it last about 2 hours, no damage though and he looked fine this morning just chewing away on the wood. He does this to all new comers around his size. I added the Gold Spot and Chocolate and he didn't even pay any attention to them. I noticed when he acts normal and on the glass, his belly is big and full but last night it looked sunken it, not sure if they are able to make themselves look a tiny bit bigger or he was just not happy, his belly was back to normal this morning. I got this is as a BEC.
