Ha very true. I've got 2 skunk loaches in mine - known for being very antisocial but mine don't bother anyone, unless they go in the castle. That belongs to the loaches. And they do pester the apple snails now and then. But I grow problem snails in my fry tank as a special treat for them and all is well. Though my tetra eat more snails than the loaches, didn't expect that. Haha
