Hi. My kids and I purchased some Nerite snails from Petco to add to our aquarium and was assured that these were in fact Nerites. One I am questionable on though. I know that two of the snails are Nerites but am not so sure about this third, that is very large. I am concerned because I don’t want any mystery snails and end up with a tank full of snails at any point. I’ve attached a few photos and was hoping someone could confirm that it is in fact a Nerite snail. I greatly appreciate your help!
