I recently purchased a juvinile yellow tang for my 10 gallon. He is the only fish. My question is how often he needs to be fed. I have been giving him about 1 1/2 inch squares of green marine algae once a day and a few flakes every other day. Is this okay or should I change what I'm doing. I woried about my ammonia going up. I only use a small filter with carbon on occasion and water changes. I don't have a skimmer do to the size of my tank. Thanks for any help.
