for snails, how often do they do this i hear they are A sexual so they just pop out new babies whenever, i have a blue snail i didnt know much about them when i got him , while he is cool i really dont want one of these snail explosions in the tank, i'm thinkin of setting up a smaller tank to move him to and use as a Q tank anyhow, but the reason i asked it today i noticed a weird little arm like thing coming out of the snails side, it wasnt his antenas, i thought it was a parasite at first but then i notice he was moving it n stuff, i'm thinkin it was tryin to make kids or somethin, anyone know how this works???
