More than likely they are copepods. I wouldn't worry about them, as they are beneficial to the tank. They are a good source of food for several species of fish.

I am glad to see they are not bad for the tank. I have copepods covering all sides of the tank and I would imagine all surfaces throughout the system. I have 2 eight inch groupers, how would the copepods benefit me? The fish are not bothered by them at all.

the ones on my glass are really really small. they are white and kinda look like small fleas, but it is hard to tell what they exactly look like because they are so small

A copepod looks like a cross between a flea and a shrimp, but they need to be looked at through a microscope. I have seen copepods or copepod-like things that are large enough to be seen without a microscope, but that was in a SW tank I had that was running for 8+ years and there was all kinds of stuff living in there other than the fish. At night with a flashlight it was like a circus in there.

I have minute little things crawling on the glass of my tank. Some of them seem to have two segments to them, while others are singles. Do you think these are copepods? Do I need to get something to eat them or just leave them be?

Leave them be, they are beneficial. Also, for those of you who are not sure what you have do a search on this board for "copepods" or "amphipods". BangGuy, Sammystingray and some others have posted some awesome pics and info on them.
