Can snails go in the same tank as betta fighting fish?

Females are non-agressive and will most often leave the snail alone. If you have a male, he most likely will. It also depends on the size of the snail, the larger the snail the less likely it will be harmed, but a larger snail in turn can injury a betta if it snaps shut on the bettas head. For the most part snails and bettas don't mix well.
