I currently have a 3 1/2" hippo tang in my 125gal. I was wondering if you can keep more then one tang in a system? I was thinking about adding a powder blue or possibly a naso tang.
Probably a smaller Naso, maybe a PBlue same size or smaller. Hippos are normally pretty peaceful but it can help to rearrange the tank a bit at intro time. IME Hippo will be subordinate to other tangs every time. They aren't much of a scrapper. All this is IME/IMO. Good luck.
