Tiny dead shrimp in sump?

[anthonys8107]

I recently noticed these tiny shrimp-like things on the walls of my sump. They don’t move, just kind of stick to the wall, at least from what I’ve seen. Is this something I should be concerned about or just leftover food caked to the walls?
(They’re all around the walls of my sump, these are close ups.)

They are pineapple sponges. Take it as a good sign.
