Looks like a hole. Did someone bite him? You have a trigger fish?

Also he hasn't eaten going on 5 months!!!!
He was eating nothing but shrimp. He refused to eat oysters mussels shrimp octopus crab meat even the little silver siders he wouldnt eat.
However Mike Goldenhead goby disappeared one day snd my eel was pretty fat and now he refuses to eat anything I place in the tank for him I'm thinking that he wants another Goldenhead goby
