I highly advise against those feeders. They tend to release too much food and will rapidly foul the water in such a small tank. Most likely your betta won't eat the food and the snail won't eat it all either.
if you are looking to add calcium to help the snail maintain a healthy shell, a tiny piece of a cuttle bone will do the trick.
