I just got a mystery snail, and put it in my tank... it seems fine, however I noticed as it was edging along my plants a black/white worm began coming out of it... I'm not sure, I have very little experience with these snails so a little help would be nice. The worm is striped, and has not left the snail yet. I'm actually not entirely sure its a worm at all, but that's what it looks like. Anyway, is it harmful to my fish, what should I do?

Can you try getting a pic of it?

I'll try. :]

Lmao! Extended siphon apparently. My bad, a little research goes a long way!

When I read your first post I was really worried for your snail. I'm glad your snail is healthy and safe

Lmao! Ya, I had to laugh at myself for a minute. I'm get so "OMGKSJGJSHJKWHJ" when I've never seen something. >_<!

And my little snail is definitely doing well! He seems to be loving the tanks large variety of fresh plants.

yeah, that was going to be my first suggestion. I knew as soon as you said it was striped what it was.

Apple snails are amazing creatures, enjoy yours.

Funny! I am glad your snail is doing well munching on plants.
