Mystery snail shell transparency??

This is a gold/ivory mystery snail who was bought many months ago.
She coexists peacefully with her tankmates (danios).
Her shell has gone translucent completely. I read about this online and I found out that calcium could be a problem. However, I did scrape off a lot of cuttlebone but the condition is still the same.
Her tank mates are all healthy and fine, and she also moves about (pretty fast for a snail) and eats a lot. She's just picky when it comes to vegetables and usually stays on algae and detritus.
Is this normal for mystery snails, or is it a condition? What can I do to help her?

If you have a high buffer I am pretty sure it makes it hard for the water hardness to change. I think it is low calcium and water hardness. I would say to dry some crushed coral maybe. take this with a grain of salt because I don´t know to much I am fairly new. hope I can help a little lol. Good luck!

 

What are the water parameters? Mystery snails require some protein in their diet rather than just algae, plants detritus, and veggies. They will pick up any left over fish food if there is any, which usually has some decent protein value as well. I use some snail food as their main staple, and supplement with occasional veggies. This is what I have been using using:

Could be calcium deficiency could be old age.
Cuttlebone could take months to breakdown and add calcium though and over time a biofilm could form on the piece and slow or stop it from releasing calcium, some people grind it to a powder to help it break down quicker to add calcium.

You can have adequate GH readings and still be calcium deficient if like magnesium and other minerals are present but the Calcium is depleted.

The only way to know for sure is to test only for calcium and not for GH in general, more specific testing.

You could try crushing cuttlebone with a hammer then grinding it further into a powder, this should make the calcium more available, quicker. Or using a liquid calcium supplement.

 

Generally the problem to cause something like this is not enough calcium. Mystery snails require a lot more care than people think. They're a wonderful clean up crew but they do require some extra care. Adding calcium now is NOT going to be a quick fix. Generally the shell that is already grown will not be repaired at this point but the new growth will come in healthier. Think of it like your hair, once the damage is done you really can't "fix" it but you can be healthier and grow better hair after it.

Another thing that can cause this is acidic water. Water that is too acidic can actually eat away at the snails shell. Usually it causes a rough texture if this is the cause
