Axolotls eat snails in the wild, but, maybe if the snail is large enough, it will be fine. I don't like snails for algea removal however. If you are skilled at keeping fish, you can use a bristlenose pleco. Ive accustomed mine to colder temps and have dwarfed it in a small tank, its the same size of the axie and has never hurt it. you might be able to try that, but I warn you that it takes skill.
