I have 3 golfball size turbosnails and the other day one was up against my powerhead causing a really annoying buzzing sound. So I gently pulled him off the glass to place him on the rocks and these brown pellets fell from under his shell, they kinda look like small mouse turds. Do snails poop? If they are giving off that much waste on a regular basis I'm going to return them to LFS, I'm aspiring for sps and this extra waste wouldn't be good,IMO.
