I have seen videos online of axolotls eating snails. I was wondeing what type of snails are safe for them to eat and if it is even a good food source. I was thinking of Japanese trap door snails, AKA chinese mystery snails. These are live bearing snails that grow to the size of golf balls. If I started a colony of them would it be safe to feed small ones to my axolotls? Maybe keep a few adults in the tank to eat up uneaten food.
