mantle collapse & scarred snail??

[snoobi]

Hi! I'm new here, and this is my first post! I'm making it for this snail I found in my garden. I have a lot of worries about that little friend.

First thing, he has white lumps I had never seen on any other snail. They're very visible with 2 main big ones, and they're on both sides of his body, the foot is fine though. It doesn't trigger any reaction if I poke them, but they intrigue me quite a bit. My first thought was scarred tissue, so I named him Kizu which means 'scar'. Does anyone have another possible answer?? 

Kizu also has mites, and I gave him a little shower because I don't know what else I can do. Please let me know if there's a better remedy. I heard the mites can hide in the snail's air conduct, so they could easily escape the showers, but I thought it might be better than nothing to give him regular rinsing...

And finally, the shell seems way too heavy and keeps falling on one side. It looks a lot like mantle collapse to me, considering the snail is also very weak. He eats some, has a fast reaction to water every time, but he just looks really exhausted. Like he can never do more than minimal movement.
I really hope it's not mantle collapse, let me know if it sounds like it to you too. Please also tell me if there's any recovery possible for that.

I put Kizu in isolation for now, because I don't know what's safer between putting him in the tank with other ones, or letting him back outside. 

Thanks in advance for your help!

Could you post a picture of the white lumps? It'll be easier to identify with pictures.

If your snail has a mite infestation, hypoasis mites are considered the best option. They are predatory and hunt down and eat the snail mites, even inside the breathing hole. However, they pose no threat to the snail, and once theharmful mites have disappeared, they die off too.
I recently rescued a snail that turned out to have mites, and I used hypoasis. I haven't seen any mites for about a week now. He was also very weak, but after applying the hypoasis mites he's started to show signs of feeling better. So that might be what is causing your snails other symptoms.
Definitely keep him isolated from the other snails, because the mites are contagious. I'd keep an eye on the others to make sure they don't have any too.

I don't know what country you live in, but you can find live hypoasis mites for sale here- www.defenders.co.uk/shop/sciarid-fly-control/hypoaspis-10k.html or often on Amazon.

Thanks for your advice! I'll definitely use hypoasis mites. I edited my post with pictures of Kizu still figuring out how the forum works.

Hi snoobi, welcome to the forum.

I also used to have a snail called Kizu - a very large wild-caught Archachatina marginata with a big white scar on his neck.

You've had some good advice from pasi9 already, I agree that it's possible the mite infestation could be making him weak. I can't see any signs of mantle collapse from the pictures you've uploaded. He looks quite skinny from the pics though, I would try to feed some nutritious food like sweet potato and also give a high protein food like raw meat, soaked cat/dog biscuits, soaked fish flakes, cooked egg yolk, or raw/unflavoured nuts like peanuts or cashews. This might help build muscle to make him less weak. Don't give a high protein food any more frequently than once a week.

The white lumps are strange, in the past when I've had snails with scars they have been flat against the skin, however those were probably old scars and this could be a more recent wound that is still healing and that's why it's raised? I'm not totally sure about this. Unfortunately we still don't know much about snail diseases/injuries etc.

Hi, thank you so much for your reply. Your Kizu must have been really beautiful!! Mine here is really skinny indeed, I'll take your advice on his diet! Maybe that could even be the reason his scars are raised, I don't know... I was paranoid he had some sort of parasite larva inside him but since nobody mentioned anything like that, I'm reassured about introducing him in the tank soon.

I'm definitely not 100% sure what is causing the raised lumps, healing wounds is my guess but it could be something else - it's possible it could be some kind of disease. I am not sure if there is a parasite infection that would present like this but I think it's unlikely. However I'd probably keep him in a separate tank for the moment if that's possible, at least until he is fully mite-free, and to enable you to keep a close eye on his eating, behaviour, and how the white patches are looking.
