I'd say no to any tang if its the same as my tank 36x18x24. I wouldnt get a copperband butterfly either. So far I have a lawnmower blenny, and 2 black false percula clownfish. I'm going to get a Royal Gramma Basslet, and a fairy wrasse. That will probably be the end of my stock list. I was planning on getting a flame angel, but since im planning corals down the road I decided against it.
