Hi, I have a new Pachytriton labiatus and his aquarium is still being fine tuned. He has lots of room in a 10 gallon tank with plenty of cool circulating water. I was going to get some guppies to put in the tank for him and wondered if I got some small snails (cleaner snails) in the tank would he try to eat them? And if so, would that be potentially harmful? Also, any recommendations on the best aquatic plants for the tank? I noticed sometimes when I buy plants at our local fish store there are snails that turn up in the tank. Thanks!
