I went to my lfs and saw in one of there tanks a snail... they werent selling as a shipment because it came with the plants. I asked if it was a snail that can cause infestation but they didnt no (main fish person wasnt there). The snail doesnt have a ramshorn shell, but a pointed shell that was a little over a half an inch. I originally thought of it as an infestation snail but since it was so big i figured not. They said they would give it to me for free since i always go there every week. Can someone help me find out what snail it is and if it can infest my tank.
