I am in the middle of eradicating a pond snail infestation. I heard that cherry barbs eat snails and thought that might be a nice way of preventing them from getting out of hand in the future. Has anyone had luck with them eating snails? Also, I have three mystery snails I want to put into that tank. Will mystery snails eat pond snails or eggs? Will cherry barbs harass mystery snails? Finally, I have heard conflicting news about cherry barbs being schooling fish. Some say yes, some say no. What say you?
