Who has any long-term experience with clown tangs? (As I am writing this, I know I need to give mine up) I've had mine ~10-11 months (purchase size ~2.5-3"", now is ~6-7"). He's very healthy and active, but over the past 2 months has gotten very aggressive, which is to be expected as I have several other Tangs. Feeding and lots of nori keeps him busy, but thats not a viable long term solution. My bigger concern is he is starting to tear up my corals, probably b/c in too small of a tank and is bored (completely tore apart a huge leather I had for a few years, picking at gonipora and pecking at other softies i have) When purchased at my LFS, I told them I had a 15o gallon and of course they said it would be fine. After the coral nipping started i did some research and found out they should really be in a 250g or larger, which is not in my future. My guess is I will have to need (soon) to give him up to someone with a large/FOWLR system.
