Are my snails ill?

[ineedhelpwithmysnail]

Hi,sorry this will be a bit of a text wall.

I have 4 young adult cornu aspersum. They've only become sexually mature in the last few months but I've had them for a year and have never had any problems with their health.

Yesterday I noticed my eldest (Pepper) had a slightly puffier mantle that was going a little over the lip of her shell. When she retracted she looked puffy and a part of her foot stuck out. I decided to bathe her and the others to see if it helped.

The next day one of my other snails (Tobasco)had a large white splodge on it's back, I wiped it off and it was almost like a creamy powder? After I removed it, a sort of chalk white with a hint of green. My snails rasp on cuttlefish bone but haven't touched the stuff recently so I was a bit worried, especially as even more came out from the mantle and in his stool.

Now one of my other snails (cinnamon) is excreting the same stuff out of her breathing pore and I'm so stressed with worry.

They've mated a few days ago so is it some kind of sperm??

I'm so confused, please help

The puffy mantle is due to mating, and since you say they recently became sexually mature it's expected they would start mating soon after reaching the mark - C. aspersum breeds a lot. Sometimes their slime changes afterwards but it's nothing to worry about. I don't know exactly whats going on without seeing a picture of the slime/substance but I recall seeing things that match this description on some of my mating snails. I have a lot and usually they are left to their own devices (except for food) so my memory is a bit of since I've actually not witnessed mating in quite a while. The new generations just 'pop up' among my terrariums.

Sometimes I'll see the same white substance coming from the breathing pore of my snails when they have come out of aestivation and are experiencing higher than usual humidity. I'll see it after mating or other periods of activity from the snails too, and remember seeing in another thread that is could be way of secreting unneeded calcium. I am unsure of this but it seems to be a normal occurrence.
