So I got tired of my puffer fish eating all of my polyps and small glass anenomes that came on some rocks in my 55g tank so I moved him to my 180. My 180 is cycled and showing 0 amm 0 nitrite 0 nitrate (success!!!!!) I have about a dozen of the large mexican turbo type snails in there for a few days that have been doing great. I moved the puffer over last night and today when I got home almost all of my snails are on the bottom of the tank upside down!!! Is he the culprit or was this some mass snail base jumping phenom i missed out on>? If he is the case I may have to ban him to the sump till I decide what to do with him......
