That sucks having to give up your tank! I have a good home for your Sailfin tang if the other deal falls through. 225 gal reef with a 75 gal sump in wall. His room mates would be 4" Orange Shoulder tang and a 4" Powder Blue, 6line Wrasse and a Pink spotted Goby. SPS dominated tank with low Bio load. Red Sea Sailfin is probably the last large fish to go into "this" tank. It will be yours or I will purchase one from my LFS. I just have to have one! One of my all time favorite fish. I could pick it up any week end.
Just pm me.
Keith.
