Another question! By the way, thanks so much for you help! I have a yellow wrasse, royal gramma, tomato clown, mandarin goby, and yellow tang now. I just put a kole and clown tang on hold at the lfs. I have a 90 gallon tank and everything is doing fine so far. Lots of caves etc for the tangs to swim in. Any opinions on adding these two after which I will be done adding fish until I lose some!!
