What are these?

In stead of making two threads I thought I'd put them in one.

I have these growing on power heads and had them on glass in the past. I'm talking about the polyp looking thing

Secondly, my zoas are exploding like they seem to for others. The frag fell off the rock to the bottom and I noticed this weird looking stuff on the frag. Any ideas?

1. Sponges
2. If its Bryopsis, DON'T do manual removal inside the tank. You will make things worst. If it is, I would throw the throw the whole rock away.
