Can you have a betta with a snail?

Snails can be an acceptable tank mate for bettas, but remember that some snails produce a lot of waste and the tank may need to be cleaned more than usual to prevent an Ammonia reading. A common type of snail that is acceptable to keep with bettas is an Apple Snail. Another thing to keep in mind with snails is that some bettas may nip at them and try to eat them. If this becomes a problem, you will want to consider removing the snail from the tank. Keep an eye on how many snails you have because if a betta eats too many snails it could lead to constipation and other digestive illnesses.
