Missoula that looks like a kind of xenia. Grows super fast and will take over a tank in short order. I personally love it because it is a nutrient hog but it MUST be isolated. Those zoas will be taken over if you don't remove it. I keep mine isolated to a frag rack. Others keep theirs on an island or in a refugium because it really does suck up those nutes like a macro algae would....but also spreads like wildfire.
Sorry, I don't know the best way to remove it aside from just cutting it off, though it will grow back. I am sure there are ways though as my urchin take chunks off my acrylic frag rack!

Thanks. It was a white spot on the rock when I bought the zoanthids and it seemed to sprout overnight. Wish me luck on moving/removing it.
Yes, pest majano anemones. You'll want to inject them with a commercially available aiptasia killer or a kalk slurry.
The coral skeleton appears to have sponge growth on it, and the one behind it is also a sponge.
Was afraid of that, beastly looking thing. Figured out what the ones in the front were by going to Richards site. Tube Corals. They are alive and kicking, extended really nicely this morning. You're right on closer examination today about the sponge, the yellow piece in the back appears to be the base of a sponge that broke off. Thanks!

To me, the yellow of the skeleton doesn't look like the same color or texture as the sponge. I believe it to be the receding skin of the cup coral. Unless were talking about something different than the skin going up the skeleton of the coral.
What is this?

I have seen a few fine red tentacles higher in the tank on some of the live rock and I wasn't sure if they were fibers or critters.
Early this morning I saw more than fibers.
The pictures are through the glass along the 3" of Argonite on the bottom of the tank.
Do you know what this is???
Is it a problem?

Hair worm. They are cool.
Yep, psuedocorynactis. Ball anemone. Some can pack a sting, some seem benign. http://www.advancedaquarist.com/2002/10/inverts

Different people have different opinions on ball nems really. Mine have never exploded in number and I think they are cute. Sushi does not like them I know 
Yours are Pseudocorynactis caribbeorum. Unless I am wrong, just from reading about them and observing they are not photosynthetic. They will only expand at night and unless fed they will stay white-light orange. They will not be colorful if not fed and not multiply much either, just my experience. But, if you feed them they do. It is just hard since they don't tend to grow in the light so it is hard to reach them.
