It is only a 55 gallon. There are 4 fish royal gamma, clown, wrasse and the blenny. It has been up since Jan 2011/ For the CUC I have about 3 blue legged hermits, a peppermint shrimp, the very important bristle worms, 3 banded trochus, 5 nassaruis.4 truban and a few stromatellas. I change about 5 gallons a water a week sometimes more just depending how things are going. I feed my tank once a week which means I feed mysis to the whole tank, silversides to the anemones and I turn off the pumps. I feed the fish twice a day once with flakes formula two and rods food. I also have a refugium, skimmer and 2 koralias. I use a mag float to clean my glass once a day.
