Hello, I recently conducted my first fish rescue (yay! 4 adf and 7 Zebra Danio in a 10 gallon with 3 snails. Two of the snails were dead, so there is only one actually (got all of them plus the tank for 20 bucks) and the lady I bought them from didn't know what kind of snails they were, and I don't know either. Can someone ID it please? Thank you.
