Ok I have a big snail in my tank and everytime it is on something and not in a corner my guppies attack it and he gets scared and closes up and winds up floating on top of the tank. Whats the deal and is there anything I can do for the poor little guy. I feel bad that he is being picked on litteraly lol, but am afraid of him dying if he is floating tooo long before i notice. Plus its getting annoying.
