In a tank that big, I would say go for it. I think bobo might also enjoy some little fish in the tank. My puffer loved to swim with my damsels. He also loved to swim through the mini school of chromis that I have. i don't know anything about burfish. SO I don't know if they are compatable. I think bobo would like some tank mates. I love cow fish. I think that cow and puffer would be great.
Maybe someone out there will remember... Aren't there three fish in the wild often found together??? Isn't it like a lion, and a puffer and something else, or am I way off base. I know about the 3 buddies in the ocean staying together, I just forgot what they were.
