I have a 150 gallon tank, extra high, which means the tank is 4 foot in length, 2 foot wide, 30 inches high. Would this be large enough for small 3" clown tang? My tank currently has (3) 2.5" small purple tangs, 2 clown fish and 1 cleaner wrasse. The tank isn't filled but half way with live rock to give swimming room. The tangs seems to get along pretty well, they have been in the tank for at least 10 months. I know I couldn't get away with a yellow tang (tried it):sad1:, but the clown tang has a different body shape. Let me know.
