I definitely want a good sprinkling of Tangs and I'd like a few that weren't so common. I'm hoping my system will be large enough and that my dedication will be enough to attempt a few fish that are considered difficult. I'm not worried about Ich as I put all fish through hypo before placing in the display. A collection of Achilles, PBT, Clown Tang, Emperor Angel and Regal Angel would look great as centrepiece fish.
