I just bought a 75 gal tank, in the tank were 2 spotted puffer fish, along with some zoanthids, mushrooms, and a few other soft corals. I've tried to do some research, and it says these fish aren't reef safe. Has anyone had any experience keeping these fish in reef tanks? Or should I keep them in a fish only tank? I also saw that it's not smart to keep 2 puffer fish in a tank together, should I separate them, or are they okay together, since they were already?
