Hope he doesn't get the same high humidity problem that caused another giant tank to get shut down after only a few months.
That thing is MASSSIIIIIVVVVVEEEE!!!!!!
BTW, I think Fred is an Elongate tang (A.mata), one of my fav. fish.
I have a baby one now in my 220g reef, but I'm not planning to build him a new tank/home like that crazy reefer.
