Not sure what these are...

Sorry for the quality of the pic, I had trouble getting it to focus correctly. Anyway, can anyone tell me what these are? They are tiny, translucent, and do not seem to move.

My tank is cycling, about 2.5 weeks old. These showed up a few days ago I think, on one of my pieces of live rock.

Thanks!

Most probably sponges. Filter feeders and beneficial.

Species of Tunicate?
