Stocking 55 gal tank... please help!

The tank is too small for the tang. Regals are big swimmers, and need lots of space, and a 15" wide tank won't give them ample "turnaround" room.

That was my concern about the blue hippo tang. Would the yellow belly blue tang be okay for a 110 gallon tank? I thought these were one and the same, but this website indicates that the yellow belly is smaller. What is your opinion? How about the yellow tang? Thank you for the information.
