ID for these...ummm....things please

I have two groups of what look like some sort of eggs. I will try and attach some pics. The first ones are orange with darker centres. The others are black and white. They only appear in the one cluster, nowhere else. My tank is still cycling and has no critters or fish other than what hitched a ride.

Heres the second lot. Sorry for the fuzzy pics. These are the best of about 10 attempts.

Tim,

Those are two different species of colonial tunicates (sea squirts).

Thanks. I have a few of them on the rock.

tim,
where did you get your live rock from?
