Looks like an amphipod.

I have a lot of them I'm noticing I picked up a rock and a saw a lot running from under it

Most likely an amphipod and that was my first guess too, and yes especially if you have many under a rock, but there are some similar creatures as well, check amphipods on that link I posted to see if that is indeed exactly what you are seeing.

Looks like fish & coral food. If they are under the rocks, probably eat detritus, not corals or softies, or fish.

Looks like it but mine is a bit more reddish
This says it's good so I'm confused

There are different types of amphipods and copepods, but typically amphipods are shaped like a comma and move around pretty quick, mostly stay in dark areas and come out at night, but yes both amphipods and copepods are very beneficial, as are some types of isopods too.
Save the link, you'll need it down the road I'm sure.

Yeah I'm still confused on how they got in I dip everything before being placed in my tank

Have you put live (un-dipped) plants in your system?

Live rock, live food!, or they sneaked in at night. Time to build a wall?

Good hitchhiker!

Many of us go out of our way to have amphipods or copepods, they actually sell them online.
I have a refugium solely for their reproduction needs, the fish benefit from them greatly, and if you have fish like mandarins or anthia, certain wrasses, they are pretty much a must have for success in keeping those.

Nope I dip everything, only one thing wasn't dipped and that was one live rock
Haha I guess I'm lucky then

I don't know if it's just bad dipping
