Couple IDs

[Darknes]

I have a few pictures of the first ID (with different contrasts). These two polyps came on some liverock I bought the other day. They open up as a large polyp with 8 branches, and close up into a large "cocoon". It appears they feed off light since they seem to point up towards the lighting on the tank. In the pictures, the one on the left is open, and the one next to it is closed up.

The other ID is too small to take a photo of. I have thousands of tiny critters that are all over the glass on the tank. They are almost too small to see with the naked eye, and all I can make out is they have an oval body. They move about on the glass as well. I haven't ever seen them before in my tank.

Thanks.

The second ID sounds like Pods, Copapods, Amphapods etc. They should grow up into about 1/4" critters that your fish will love to snack on.
The pictures look like Anthelia to me.
But I suck at the ID game so take me with a grain of salt.

Darkness,

They are commonly referred to as wood polyps.

Thanks guys, that's what it is! What a cool hitch-hiker!

Madman, I didn't even realize there was another growing there, lol.

As for the other ID, they're just so small but I suppose they could be amphipod babies. I'll keep an eye on them to see if they get bigger.
