ID some stuff

[theofilos]

Hey everyone. I got some stuff for ID from my 200g if anyone can help I'd be grateful.

1) Round coral. It only comes out some minutes after the lights are on. It's only one and it has grown a lot since I first saw it.

2) Tons of them in a single rock. They aren't mushrooms but something related?

3) These are everywhere. They aren't aptaisia I'm pretty sure as their tentacles and length are different from aptaisia right (I think ... :P)? Any clues on what they are?

4.) Those little blue faces is it some type of sponge? They have a yellow line in front of them and the rest of the body is light blue.

5.) This is a sponge right? After I had to leave the rock out for 5 hours some pieces have died off it seems. This is the dead one I am talking. I am having this type of them in pink black blue and white color most of them are alive though!

5th picture down is Aiptasia ;)

[theofilos]

Keep in mind 4 & 5 & 6 are exactly the same thing. Maybe this photo makes it look more like Aptaisia than the other photo.

^^ they're hydroids, not aiptasia

[Aaroneous]

I vote hydroids on #3 (pic 4) and maybe pics 5 & 6...hard to tell.

[theofilos]

Anything on the other stuff?

[reefscape15]

Looks like a Mushroom of some sort in pics 1 & 2. Picture 3 maybe Zoas that are closed up (Are the rocks new or have you had them a while?). Pics 4, 5, & 6 look like unidentified Yellow Polyps which can be very annoying and hard to get rid of. Pics 7 & 8 maybe Tunicates, again if the rock is new or old/cured or not? Pic 9 looks like some type of sponge. Thats my best shot

[theofilos]

I have the rock since 25 of January. It had been in the LFS for around 2 weeks before I got it.

Hello,

4 is a single sea squirt
and 5 is an encrusting colony of sea squirts...
not quit sure with the ones before, hydroids look a little bit different (more like a brush); for me it resembles more to yellow zoanthus http://www.reeflex.net/tiere/796_Parazoanthus_axinellae.htm

regards

#1 looks like a button polyp that has lost a lot of color.

[theofilos]

It's not a button polyp I believe. Close but something different. OH! and I saw my first aptaisia :D . Getting vinegar ready hehehe.
