Hi! I have a mystery snail ( Wayl'n). The other day he climbed out of the tank and I found him on the floor in the morning. he was still damp and I tossed him back in. He opened up his shell a bit but hasn't come out or moved any. If I touch him he pulls his door shut. But my concern is that he has a pea sized cyst growing on him ( on the edge of his foot(?)). Is this normal?? Is there something I can do for it to heal?
Thanks for any help you can give me.

hm....?

I've not heard of growths on a snail's foot. It's probably benign. I don't have any suggestions for treatment or anything. Sorry I don't know more.

Mystery snails (apple snails) will come out of the water to lay eggs. Maybe you have a female. Could the "cyst" be one of her eggs?

its possible. what do you mean by chinese mystery snail. the apple snails come from america.

Oh, I didn't catch that. Mystery snails are normally apple snails which are native to South America. I'm not that familiar with species native to China.

arent they also in florida and central america?

I checked. Yes, some species are in those areas as well.

ok, cool.

How did they get the name "mystery snails"?

Robyn knows. they are all pretty much apple snails.

From the excellent source http://applesnail.net:

"Are mystery snails also apple snails? Or are they different types of snails?
A: In some sources the name apple snail and mystery snail are considered to be synonyms for the snails of the family Ampullariidae. The name apple snail refers to there size, colour and form, while the name mystery snail comes from the fact that the aquarium market didn't know what kind of snail it was or where it came from, so it was a mystery (snail) for them.
In other sources, the mystery snails are described as snails from the family Viviparidae. The snails from this family look very similar to the snails from the family Ampullariidae, but they do lack a lung and labial tentacles and are livebearing snails (hence the name Viviparidae).
Most snails sold as 'mystery snails' in the shops are Pomacea bridgesii snails."

Sorry I haven't gotten back sooner. Wal'yn's cyst/eggs/whatever, is all cleared up. It took about two weeks for him to start moving around again. Although he's a bit less active now he seems to be doing fine :D Thanks for all the advice!!!
