Help identify those critters?

[mzlskink]

There are white fast moving white bug like things on almost all corals, many are walking over sps acros, what you see here is walking all over gsp which is covered in algae

Are those pods? If they are pods why don’t I see them swimming My tank recently crashed and lots of coral are dying with okay parameters. I am wondering if those are the pests

Maybe they came out for the feast.
If you can get a closeup Pic it's possible to identify.
For now, I say pods.

Looks like either pods or something similar like ostracods. You don't see them swimming because they're a benthic species - they're not a swimming species.
