I was playing with my blue ramshorn and mystery snails yesterday and I let one crawl on my finger. I could feel his mouth the whole way but I was wondering, is that something I shouldn't do? Where he was eating it got kinda tingly and I'm thinking it was just basic nerve reaction but I thought it was funny/dumb enough to ask in the chit chat forum. They don't cause any harm right? No corrosive spit? Acid blood? The sticky stuff they excrete won't dissolve me? XD
