looks nice, but id trade in the soahl, forget about getting the blond naso, they need 180+ gallon tanks, you can mabey get away with the blue tang, but i wouldnt put any more than 2 tangs in a 90
if im thinking and understanding i would say he is thinking in terms of a pacific blue tang a.k.a regal tang or blue tang. even then that would be pushing it but alot better choice than the sohal.
u should have enoughr room for the hippo o and by the way is that yellow tangs tail getting bit by the sohal it looks like it in a pic other then that very nice upgrade.
