ok question to Lion Craze, you said that my 45gal is insufficient for my yellow tang, I was told by the fish expert there at the LFS that I could have 3 in there but it's a risk of over crowding them, I guess I'll have to conveince my g/f that we need to turn the 135gal into salt, or just buy a new 160 haha she'll be happy about that,, yeah right.... but really your the first to mention that to me.... are they fast growers?
