I was given a Purple Tang by a neighbor that is tearing down his tank. Right now I have a 120G holding tank w/ a yellow tang. They will eventually go into a very big tank, but right now I only have the 120 set up. Would these guys be okay in the tank together for a few weeks, or should I just give it to the LFS? I have a blue tang, a fire goby, and 6 line wrasse, and a clown in there right now.
