I thought it was a bug running on the outside of the glass

I have my first saltwater aquarium.
This evening after I had turned out my aquarium lights I was distracted by what appeared to be one of those tiny annoying bugs that run along your tv screen or window (they are a bit bigger than fleas and have wings) running on the glass of my aquarium. Anywho, when I went to smash it, I realized it was inside the aquarium. At first I thought a bug had gotten into the water and was moving against the glass trying to get out. It was circling and swimming in fast erradic circles (much like a bug on your tv screen or something). When I turned on the aquarium light, however, it took off like a shot toward the live rock so it was definately an aquatic 'something'.
This is the first thing I've seen come out that stumped me. What could it be?

Amphipod, most likely. Did it look like this?
Here's a thread with pics of pods... https://forums.saltwaterfish.com/t/172998/amphipods-copopods-isopods

nope- i should have mentioned it was a solid dark color (black)

How about a pic?

Moving fast circling sounds like Mysid shrimp. But all the ones I see are lighter colored.

I haven't seen him before or since... he was so small and moved so quickly and erradically I doubt I could capture him in a picture. I'll keep an eye out for him tho.

How about drawing us a picture with crayons or something? I'm dying to know what it was!
