Snail shell deteriorating--fast!

[Rastus]

Hey all.

Ive grown rather fond of my snail Gary. When I got him he had a little brown on the bottom front of his shell and the LFS said he was just growing. But whenit got bigger I was concerned. Now having paid close attention I can tell it seems to be deteriorating. Over the last two days the white part reveals twice the brown/ green color that it used to. I added baking soda and a broken up muscle shell but he keeps getting worse and I'm not sure what to do. :/

Help?

Hi!
What kind if snail?
Can you post pictures?
What are you ammonia, nitrite, nitrate and pH?
Tank mates?

Sorry- shouldve posted stats.

attached is a pretty bad picture, bit you get the point. I'm out of ammonia testers but he's in with one other dumber snail (I forget the species, I don't like him anyway) and three Rosie reds. Gary is a blue snail (says the LFS)

nitrate: 20 ppm
Nitrite: 0 ppm
Gh: 150
Kh: 120
Ph: 7.0

I have strips right now but I'm buying an API soon.

Thanks!

Try feeding him some kale or spinach. They are high in calcium. You can also add some cuttlebone in your filter or under the substrate.
