Hello everyone! I am planning on my next tank addition being a tang of some sort. At first I was set on a yellow tang, but then I saw a blue tang and really liked it. What I really want is a powder blue tang, but from what I have been reading a 72G tank is not big enough for a powder blue tang. I know that all tangs are very delicate and more susceptible to diseases than other fish. A guy from "That Fish Place" told me that the blue tang is actually more fragile than the yellow tang, so I again reconsidered my choice. So much info!!! This is my first tank so I am also looking for something that won't be too challenging to keep. Any input is appreciated, thanks!!!
