I took some better pictures of these new little guys I got with some live rock.

have a look, are they recognizable?

this is an orange guy. Sometimes he opens like the little ones underneath:

and what are these mushrooms?

and finally, this odd pair:

any help would be greatly appreciated! I've looked and looked for myself, and little luck . .

top looks like a sponge of some sort. The next is a mushroom, doesn't look like a ricordia, and the last.. I dunno a coral maybe? Do you know what kind of live rock it was (Jakarta, tonga,etc) It look to have a lot of life on it so I'm leaning more on Jakarta rock

I would put that rock in a quarantine tank. It may be a pest anemone and if it spreads you may have trouble eradicating them from your tank.

Someone should be along with a positive ID.

If it is a sponge, when moving keep it submerged always. Air can kill them.

UPDATE

. . I have also started to notice some small anemone-like guys at the base of some live rock I started the tank with. I think they are Corynactis californica, since images of these most resemble what I have. They are crowding on a lower portion of live rock, just at the substrate level. They aren't harming anybody now, but I am noticing about a dozen of them, though most are still tiny (so pictures do not turn out - they just blend in)

Everything else seems to be doing fine. I don't have a QT just yet, so I'm getting a 10 gallon tomorrow!
