Hi Bryan, I started a new thread for your query. Bettas? Do you mean the common fighting fish? If so, their snail eating 'capabilities' are purely based on their temperaments and curiosity, in my experience... The other bettas (especially the wild ones) might have a better inclinity to eating snails...
But what are the other fauna you are keeping now? Also, your tank size? With more information, we can help you suggest other snail eaters (if necessasry).
