I'm seeing conflicting information on just how big a tank that a flame wrasse requires. I've seen it from 50 all the way to 90, but I want one very very much for my future FOWLR tank (which at present is only 50g), so I'd like some opinions. Could I keep just one? The 50's 4ft long...would it make much difference if I upgraded to a taller tank that's still 4 feet long?
