Darn, you beat me to it. XD I was going to offer my excess Malaysian Trumpet snails for sale too but I was waiting for them to get bigger. Just FYI, I think they're really hardy so unless the temp is going to be in the 50's for an extended period of time, they should be okay without heat packs. Don't know if you want to pass that info along to potential buyers or not. Good luck selling them!
