Should I be worried about this shell

[RafaelAtkinsonJr]

So about two weeks ago I noticed that my hermit crabs shell (Mr crabs) has been turning an aqua color. Should I be worried about this?

Nothing I would worry about.

I would not be worried about it either.
Shells change color the longer they are in the display as algae and/or biologic material take up residence.

Adds character!

I agree with the above; looks nice!

Okay cool. Just wondering. Thanks for the input!
