little bugs excavating under my rock

[hooked]

Hello everyone,

I have noticed 2 bugs excavating under a piece of rock. I was hoping somebody would have a clue on what they are. Both are around 1/4 long, I can see a head with 2 antennas. It looks like they have a tail that they tuck under there bodies. I can see 2 legs on the back of them that they use to move around with. I can see them picking up the sand with 2 front legs that are smaller then the back. Both are a cream or clear color, really hard to tell since they will not come all the way out from under the rock.
That is the best I can describe them and hope somebody will have an idea.

Thanks,

Souinds like Grammaris shrimp.

Sounds like big pods to me, especially the tail tucked under. They are good things but I would be suprised if there wasn't more in there somewhere.

Should be nothing to worry about, as they are very good to have. Make sure whatever it is doesn't excavate so much that your rocks fall.

Lucky for me they are under a rock all by itself
