My wife brought home two of the meanist green spotted puffer fish the other day. We have a small 20 gallon we were doing to put them and a dragon fish in. I was looking around and found that they are particularly fond of snails aqnd i was wondering if anyone knew any snails that were small enough for these juvenille puffer(1 and 1/2 inches) could eat . They said they could eat snails about the size of there eye balls. Is anyone familiar with these fish.
