ID This?

[NaCl_H2O]

Can anyone identify this "Thing". I have had it growing in my tank for about 4-6 months. It started fairly small and is currently about the size of a quarter in diameter, it will rotate about 90deg now & then.

Give it your best shot (not the best picture)? I am really curious?

kinda hard to tell but if i had to guess i would say a button polyp or an aptasia

its a snake-locks anemone, a.k.a. anemonia viridis (=sulcata). it will spread to look like a colony of zoathids. but its in the same ssp as majano.
ornamental, reef safe, harmful to fish and corals. carnivorous, filter feeder, photosythetic, does not require supplemental feeding. needs light , strong water motion and cool water temps (<74'f)
htht!

Wait a minute,,, "reef safe, harmfull to fish and corals"??? Am I missing something here?

[dan]

maybe it lives on a reef with NO fish or corals. he! he!he! in that case it's reef safe

[reefer]

that's what my book says..... it has the same description for mushrooms and other corals too!

Can you get a pic a little further away? I almost looks like aptasia, but the tentacles are too short.

I will attempt a better picture this evening - My Canon ELPH S300 isn't the best for Aquarium pics :(

I don't think this is an aiptasia, I have removed some of these. This has a broad body (Multi-color) with short tentacles around the edges.

Also, any hints on resizing parameters for digital pics before I post so I don't get the HUGE version like the last one?

Thx - Steve

I have some pretty amazing variations of the aiptasias. Some long tentacles, some short, some all brown, some frosted with lots of white.
If you give me one, I'll feed it to the Berghia. If they eat it, its aiptasia. Aiptasia start to reproduce like wild fire once they hit this size. If
you have dozens of little ones in a couple months, I'd get all them out then. Until then, and without more pictures, assume its viridis. I have
2 little anemones from the coast that don't look a whole lot different that this. Does it have a long stalk or short one?

Here is another picture, a little better I think?

A fairly long stalk I think, but it is growing up in between rocks and I'm not positive.
Any ideas?

Bump - for the better picture!
