I have a new tank in the process of cycling and I was checking it because the driftwood is coated in that fluffy white mold/algae? Anyway I noticed little worm like things and freaked out but then I realized it was poop coming from a tiny TINY baby snail. I have no idea where this guy came from! I have a single ivory mystery snail in my established 20 gallon, but I’ve had them for three months by themselves so I wouldn’t think it came from them? Anyway, I’m not sure what to do they’re welcome to stay of course but I’m not sure how to raise such a tiny thing? All I can think is calcium for the shell? Any advice would help!
