Mystery Snail

[sic0198]

I have a betta in a 2.3 minibow tank, I have a snall filter and a heater, could I add a mystery snail in there?

In general a mystery snail is considered to be about a 2.5 gallon per snail bioload. It migh be OK until it starts to become full sized but then it would be an overload with the betta. If you are willing to do the maintenance, it could be done.
