Hey on compatibility issues Let me just say I have a 125 with
1 yellow belly hippo tang med.
1 blue hippo tang sm.
1 large sailfin tang
1 large yellow tang
1 small yellow tang
1 med purple tang
1 med Kole tang
Tangs to come are the black tang, jeweled tang, and blonde naso, also the elusive achillies tang
and for the tang police when they need it they willbe moving to a 300g in the next couple of years
so I guess what I'm saying is get them both get them both the more tangs the better they all treat each other
