A few days ago I got a Blue Mystery Snail for my U. Gibba tank. It's pretty big, about 1 1/2" shell. The problem is, I have a "colony" of brown pond snails in the same tank and I'm not sure if they will get along. I have seen the pond snails on the blue mystery snail's shell and even on his actual body. I'm worried that they might be agitating him/her or that the pond snails might try to eat him (I have seen their carnivorous behavior, eating dead fish or insects)
Can they live together?
