There's a strange... growth that's been on my rock since day one. Originally, I thought it was a dead sponge, since it's white and seems semi-squishy when I touch it, and it's definitely sessile; it hasn't moved at all. But, it's been around for almost 2 months now without any change in appearance, so I'm wondering if this thing is still alive.
I originally left them on the rock when I pre-cured them, since I was actually worried about the rock being too clean, and I thought a dying/dead creature would be a decent ammonia source.
There's 3 of them (that I can see) on my one rock, which was from Fiji I believe. This one pretty much had the most life on it, compared to my other rocks; grass algae, bubble algae, worms, probably my Stomatella snail, etc. Can anyone help my identify these things and if I need to get rid of them? Thanks!

Also, there's another hitchhiker I just found. I don't recall seeing this before; if it was on the rock originally, it's grown a lot since I first put it in. It's very small; smaller than the other organism. There's something that looks similar on the top of the rock too.
Could it be a feather duster? I used a baster to spray some water at it and the little tentacles retracted into the tube.
