Yesterday one of my cappuccino snails attached himself to the glass and remained almost motionless for about 8 hours while he secreted a while slime string from the top of the head. On the picture a part of it is shown when it dropped down. After he was done releasing the white substance, he stormed off at the usual pace and joined the rest of the cleaning crew. I didn't see where the slime went, as I wasn't home until late.. Is he sick perhaps? I also attach a stopmotion video
