What are these?

Not worried just curious. They kinda look like a larval fry with a shrimp tail. And the fold up like shrimp.

Also attracted to light.

Thanks.

I'd say some sort of copopod

There is a slight possibility that they are baby ghost shrimp. I had put a few buried shrimp in there for algae control and as feeders.
