I bought a nerite and mystery snail today and added it to my 29 gallon tank. A couple minutes after putting the snails into the tank my two small clown loaches found them. I saw one of them nibbling at the nerite snail and immediately looked up whether they like snails and what do you know they love them. I took both snails out and put them in a 10 gallon platy/guppy breed tank. Nothing brothers the snails in there and i'm wondering are they fine to stay in there long term? I have a sponge on the intake filter piece and also a very good top for the ten gallon tank so I don't think they'll be escaping but what would happen if they did get out? Would I have to search the room for them and would they even survive out of water? Also do I have to feed these snails, don't they just eat aquarium waste in the gravel and stuff?
