I would like to get a blue tang (Paracanthurus hepatus) for my 72 gallon. I haven't set up the 72 yet and it might be as long as 6 months before I can get it 100% completed and ready to occupy (Most likely 3 months, but could take as long as 6). I found a tiny blue tang that is about the size of a quarter (or smaller.... it's really tiny). I really wanted to raise a tiny one. I have a 12 gallon tank that is ready to go for fish. (cycled) Could I keep it in a 12 while I get the larger tank ready? How long would be pushing it for the fish's comfort? It would be the only occupant and will be spoiled. Thanks!
