Maybe amphipods or copepods?

Are they moving fast or slow?

+1.

not sure what they are. I can say my tank has those as well. I keep them cleaned off the three sides I look through, and let the rest go. my tank is healthy, so whatever they are they aren't hurting anyone. at that point, I am not sure an exact name is all that important. hopefully someone out there knows and can give us both a name to put on them.

Could be one of several things, none of which I'd think of as harmful.
Scroll down this page (linked included here) and see which one closes resembles what you are seeing.

Kind of looks like a tiny starfish of sorts: The larger, blurry photo.

Sounds like hydroids

Some bigger ones in my tank:

yea,, ok,,, so now I came home from being gone 4 1 day and 1 night,,, there must have been 50,000 of the little sand grain sized ones all over my glass. This cant be good . they r so small I almost didnt notice them, but when I idi,, holly cow, soooo many!!!

^^^
thats it

+1 Hydroids. thats the larval stage. They'll eventually fall of the glass and make little tubes on rocks, sometimes in bunches(colonial hydroids). They can sting corals/fish, but usally they will go away on their own. They are very common in new aquariums, and may reappear periodically over time only to fade on their own. Dont panic, its nothing earth shattering.

Or they can turn into jellyfish

Great video here on hydroids turning into jellies - http://vimeo.com/12949246

to quote ddelozier, not earth shattering to have jellies either. You probably won't even notice unless you are looking. They are really tiny and don't live long.
