Okay I'm going to apologize in advance. I'm not very knowledgeable about mystery snail anatomy so I might be about to embarrass my self tremendously.
So I've had this snail for about a week and today I noticed a white worm looking thing coming out of its "vent"(the part they poop out of). It's extremely skinny and tapered to a point. It looks a lot like the snails antennae. It moved around and would come out more or less. At its longest it was ~1/2". Sorry for the bad picture I only have my cell phone. It's the little curved white thing. Its not very far out at all in the pic.
I can find very little information on snail parasites and nothing that matches the description. So idk. If it is a parasite is there anything I can do about it? A medication that won't hurt or kill the snail? Or is it something else?
I also want to note that I'm pretty sure this snail is a male and I've seen his eh reproductive organ so I feel like I know what that looks like. Though they can change the shape of everything else so maybe they can change that too.
I took a second picture, it's out quite far you can see it from the back.
