I am thinking about starting a pea puffer tank... a ten gallon with about three fish. I know very little about the fish, I know they are aggressive, and when they get bored they go on killing sprees, and they love snails in a entree type of way, but that is about it. Could you maybe educate me a bit? I was really confused when I saw them in the same tank as a crayfish at the LFS. I thought you couldn't keep them with anything. Could they be with shrimp? Seems like they would chomp them up... Is ten gallons enough for three pea puffers?
