I've got a whole bunch of snails that came with some plants I bought

I keep my plants in a little 2 gal tank, with 2 feeders that I decided to save. For a long time there was nothing, then just a couple weeks ago all the snails hatched (or at least they grew big enough for me to see) and theres tons! And there's still the original 5 giant ones who were the first... They're bigger than the fish o.O. I also find they produce more waste then the fish

I've got no clue what kind of snails they are though...
After that long ramble, I would not recomend buying snails, because as spookster mentioned, they get into your filter and can run rampid.
