WOW! That is the coolest tank I have EVER seen! I am going to make my 18o like yours. Do your yellow tangs school? If so, then I want 3 also. That would be neat. Do your Hippo's fight at all? 2 Hippos would be cool also, but I would rather have 1 Sohal, 1 Sailfin, 3 Yellows, 2 Hippos, 1 Powder Blue, 1 Queen Angel, 1 Regal angel, 5 Blue/Green Chromis, 2 Clowns, Diamond Watchmen Goby, Yellow watchmen Goby. Is that way too much?
