i have hundreds in my tank. i also have 10 turbos. the little snails probably came on your live rock and they will multiply but they stay small. my problem is i have to watch when i clean my glass because my tank is made of acrylic. one tiny snail on your magnet can really make a mess. that little guy can really be a cut up :x :cry2:
