My only hitchhiker:( help!

What is this little guy. Seems to suck in with both holes 

 

also. I can’t seem to find much else on my live rock. Is that bad?

Looks like either a sponge or a tunicate. I'd lean toward tunicate since it has two separate holes. The picture is blurry, but does it look like this, just smaller with less holes?

Yessir looks similar with less holes and different color. It also sucks it. Seems like it’s sucking in water. If I tap the glass it also sucks in. Seems to be a tunicate.

 

any tips on my live rock? Seems that there’s little life I can actually see. (I know there’s all kinds of life on it)

If it's sucking water, I'd agree it's not a sponge and almost certainly a tunicate. Not much to do for your liverock - just keep your tank healthy and long term you will end up with all kinds of cool stuff living in your tank. Don't get discouraged if they die off - tunicates are filter feeders and there isn't so much to eat in a new tank - as your tank matures and you add corals, you will get all kinds of neat stuff (and probably some bad stuff too).
