I jacked this pic from another post - but I have these exact things (spotted about 6 so far) in my 12g jbj nano cube that I filled with 8lbs of lr from the lfs. I have killed one with my glass scraper and like 6 seconds later my snail popped up from the sand and starting eating on it. I know they have like a hard "shell"... it wasnt all gooey. I figured they were a type of bad flatworm... but I thought they were toxic - why didnt my snail bite the dust? should I leave em?
