Fish Identification please

I recently began caring for a 300 gallon tank at a veterinarian clinic. They were going to tear it down if they couldn't find someone to help with it. Bad photo but hopefully someone will recognize it. Wanting to add other fish to this tank so really wanting information on this large guy. Thanks

He sometimes chases a naso tang that is also in the tank

Well aggressive and about 6 inches long. Not great. Wanting to add color to this tank. Suggestions on tank mates? I do not want to turn this into an aggressive tank. It is a large square tank with plumbing all in the center. Other fish, one large pajama cardinal, bristle tooth tang, naso tang, pair of white and black clowns and 5 black mollies. Will be adding some peppermint shrimp due to aptasia.
