I havea 125 gal fish only tank and tried to have a Fiji Puffer, the fish was truly beatuful but the little guy was one agressive fish!!!!!!! ( I understand they are fairly passive and might have been an "individual fish personality") it went after my percula clowns, Threadfin butterfly and foxface, not just once in a while but all the time and quite agressively so I took the little
[hr]
back to the LFS. That was my experience with this puffer, again that may have been an isolated incident and I just may try to introduce another Fiji puffer but I will let the rest of my fish recover from the pounding they received.
