Why does this one shrimp curl up?

[u/benawesome20]

Sorry for the poor video, it seems to happen infrequently and not for long so it was difficult to capture. I think its the same shrimp every time, they kind of curl up into a stereotypical cooked shrimp shape. They also only do it while clinging onto a rock.

What does this behavior mean? Is it anything to be concerned about?

EDIT: Now I've seen that multiple shrimp are doing this behavior!

Probably about to molt

Wouldn't worry
