So I was hoping to get a nerite snail, but I am unsure if they have them near where I live. So question on what's your opinions on mystery snails? I can't afford having a snail explosion and my tank is only 3 gallons, it has a filter, and is heated. and it gets a 50% water change a week and a full cleaning once a month. I don't know anything about snails really so any input would be valued. Thanks :)
