i used to bring them back to a highly disliked lfs, they have a snail only tank, but i'm guessin they feed um to the clown loaches :dk:
Just keep your eye on lookin for eggs, looks like snot ,can be floating or attached to something...easy to get rid of.
they usually come in on plants , so if the plants are hardy, you can give um a bleach dip, 10%bleach, 90% water, timer on for exactly 90 seconds ,and then a real good rinse , till ya cant smell the bleach anymore. No snails . I know you said you cant stand actually killing them, but when they hitchhike in on plants, you dont usually see them,so its easier.
jk, sounds like you really hate snails and find gratification in doing them in... wish i had your ,well not YOUR balls, yrs ago when my tank had them.( You guys know what i mean). Jeez, i was trapping them in a small glass jar with bait , then dumping um off at the lfs,,,how rediculous it seems now. Glad i heard about the bleach dip since then.
