I bougth a new plant from my lfs about 2 weeks ago, after putting it in the tank i noticed 1 snail - OK, I though, a freebie from the lfs!! - But now I have about 7 snails, Is this normal and is it OK?
Just watch out for them -- they multiply fast. I had "one" snail hitch a ride in on a plant and I thought it was kind of cool until I started removing 4-5 of them on a daily basis!
