A fish store near me has got some golden apple snails in. Now I know there are 2 types of GAS: Pomacea canaliculata and Pomacea bridgesii. Pomacea bridgesii as far as I know are the ones that don't eat plants. I asked in the store if they would eat plants and the lady said no but when I asked which variety of snail it was she said she didn't know so I don't trust her assumption that they won't eat plants.
Are there any ways that I can tell for certain which variety the snail is by looking at it?
They are smaller than a golfball, so they could be any type according to the size.
I'd really like to get some as I know relatively little about snails, and I want to expand my knowledge onto things other than just fish, but I also don't want them to ruin all my plants.
