Live rock bombardment

[pstreet]

Any idea what these may be? It's one of a few things living (and multiplying) on a small rock. I'll be adding other "wha??" to this thread, all from the same rock.

Looks like a ball anemone to me. Harmless little guys. The tend to stay pretty small...maybe a half-inch in diameter.

Thanks, Jlmawp!

Here's another mystery creature on the same rock. I went to take a photo and, under magnification, saw it drawing in weblike threads with debris attached. After the threads were draw in, it released 4-5 small white oval bits. Not sure if they were attached to threads or not since it happened so fast. A short time later, it was again drawing in thin weblike threads with debris attached. I've noticed 'hair' (which I assumed was cat fur) in spots round the aquarium, but now wonder if this might be the culprit. I have a video, but am unable to upload (probably too large!).

Next to this is one branch of leather coral that's not looking too hot: the base has a yellowish cast (normally purple-brown) and is 'wilting', although polops still appear to be opening etc.

Any ideas?

Yeah, I have a couple of these guys as well. They do the exact same thing. Not sure what they are though. I've noticied some that come from under the sand, and others that build little spires like in your picture.

Depends on a lot of factors. Age of tank, quality of water, etc. Can you post some levels and details of your tank?

I replied to this address ago, but my phone twitches and doesn't always send.

All parms are good. I've been told it may be a tube snail, which would account for the leather next to it drooping.
