get a water bottle and put a piece of cucumber in it and maybe some gravel to way it down. let the bottle soke in the tank over night and the snails should be in the bottle/ take the bottle out and take the snails out. repeat if there are more snails. always worked for me
I have a ton of snails in my wet/dry. I've just sort of let them be and tried to live with them but I think it's time to get them out of there. I'm going to give this a try.
