Crab with little bugs on him?

[lastlight]

I know exactly what you're referring to. My green emerald had these and they are so fast. They remind me of electrons orbiting nucleus.

When the crab would shed I noticed the bugs were gone for a while then would slowly return. They didn't seem to be harmful. Mine were orange.

They are fast... creepy fast! The crab does look dull so I bet its the exact same thing then, he looks ready to molt. Well, I am glad they are not dangerous to him.

Thanks for the info!!
