I was hanging out in the reef section and mentioned I had purchaced a rather small ( for the time being) blue tang. My original question was in regards to damsels and the easiest way to get them out of the tank, which has 50+ lbs of live rock, and is a 45 gallon long. I had done some reading and asked my LFS If it would be cool. Everything seemed positive. But a couple of responses to my damsel question led me to believe I made a bad mistake. Hopefully someone could help shed a little light as to why getting a blue tang in a 45 g tank is bad. If he does, or when he gets too big I can take him back, or I can take him back now before he gets settled.Thanks
