Hi guys recently I have been wondering if I am feeding my fish enough? I have a small scopas tang, small heniochus butterfly, and two clowns in one tank and two sissortail gobies in another. In the larger tank I feed seaweed every other day in the morning for my tang and butterfly and than towards the night I feed about one to two cubes of frozen food between the two tanks. Usually the days I feed the seaweed I only defrost one cube and on days with no seaweed I defrost two cubes. In my bigger tank I portion on the cubes usually into 2-3 servings and everything I put into the tank is eaten. Same for my sissortail gobies. Is this sufficient enough?
