Green spots on Mystery Snail

Has anyone seen these green spots appear on their mystery snails? If so, do you know what causes them? I seem to get them a lot on my mystery snails as they get older.

 

Its kinda the same color as Cyanobacteria. Do you see these spots anywhere else?

 

Only on my mystery snails, and they appear all over the shell, not in just one particular area.

 

Did you just get the snail recently?

 

No, all of the snails i own I have had from hatching egg clutches. They seem to do just fine until they get to be about 6 months old or so and then they get these green spots. This has been happening around the last year or so, I didn't seem to have an issue before then.

 

Im guessing it is some type of algae.

Wouldn't algae come off their shell? I've taken a soft toothbrush to it, but it just doesn't come off, and stays on the shell after death (I keep all their shells).

 

Are your snails dying early that have these spots ?

 

I have that come and go on my mysterys over the years with no issues. The ottos like to help out

It doesn't seem like it. They all seem to survive to about the one year mark and get to be about 2 inches. A lot of them die due to mantle collapses, but usually towards the end of their life span. I've always wondered if maybe it's a bruise of some sort, if that could be possible, just because it's the exact same color as their blood. Vigorous mating...being slammed up against a hard decoration or something.

 

How bizarre !! It’s a mystery ! Pun not intended …

 

I cant find anything on green spots. Do you have a pic of one of the old dry shells?

Here are some. I had to wet them down to be able to get the green to show up on the pic
