I way overfeed. I feed the cubes of brine, mysis, the mixture packet that has a white cube mixed in stuff, some algae specifc marine cubes, formula one flakes and their pellets, 2 different kinds of seaweed dry stuff, plus I made a big cube of food that has a mixture of seafood including clam, shrimp, mussels, and other things because I have an aggressive tank. I drop some of this in the big tank every few days as well. The poweder would chow down on everything. I feed the seaweed usually daily in the morning wihtout anything else. Everything is hungry after a long night. I would put in other food a few hours later. Then right before lights off at night I feed again. He always ate everything and anything. I dont think I had any issues with another tang beating up on him. He didn't have any torn fins and I never saw any aggression in the tank. All the fish are on the smaller side and he was one of the largest fish in the tank at about three and a half to four inches across.
