weird looking mini shrimp?

[NewGoby]

First of all, sorry for the terrible images.. i made them using my phone,
I just noticed this small critter on my rockwork, it's completely white, has two antenna, moves in a skittish way, and has a long body.

First thing I thought of, was it being small baby shrimp.. although it seems far too small, it's roughly 1mm in length, and 0.5mm across.

what is it, and is it a threat to my corals / the animals in my tank?

And what are the small 'twirly' things under the rest circle & under the animal?

Can't tell by the phone pic but it sounds like an Amphipod.

Google Amphipod Gammarid.

The white circles are spirorbid worms. Harmless
