When I was at my LFS (http://www.natyu.ne.jp/) last night, I saw something new that hadn't been labeled or yet put up on their website. When I asked what it was, the guys at the store confessed they didn't know what it was.

The guy I spoke to said it was an import from Indonesia that he'd narrowed it down to a small, colonial variety of anemone he'd found in a Japanese directory of marine species. The photo that looked closest was a species named as Mesactinia ganensis. Though the photo showed a brown and white morph, the description said that green varieties sometimes appeared.

Searching on Google doesn't reveal much beyond the fact the species name above exists (no photos or descriptions, just recorded as an anemone species).

Does anyone have an idea what this might be? Is it seen in the US hobby? If someone recognises it, what would be the likely care requirements? Even if you don't, would you hazard a guess that it would do well in a mixed tank of softies, LPS and a couple of SPS? I have 1 x 150w Radium plus 4 x T5s over a 18" deep tank. My main concerns would both be creating the right conditions for it and also ensuring I'm not buying a potential pest, which, even if pretty, will take over the tank.

The individual anemones are not much bigger across than a People Eater Paly - maybe half an inch at most. I'd estimate that there are 10-12 on the small rock in the picture. Sorry it's so small. I didn't have the camera with me last night and so this is the LFS shot (he's agreed to keep for me until next week so I can do some research).

Matt - I'm looking at you in particular for advice. When searching for answers last night I came across a post by you on another forum somewhere (not RC) IDing another anemone. I need one of the Gods of marine lore to help with this one!

Thanks Andy. The first thing I thought when I saw them was that they'd got some very cool zoanthids and then I looked more closely and was even more intrigued...

Thanks both. Certainly very similar looking, but, as you say, the size is very different and I assume the GGAs are cold water species from the Google info.

No idea what so ever as to an ID. Superficially they appear grossly similar to flower anemones, so lacking any other reference point I'd try giving them a similar environment.... strong lighting, low-ish flow, feeding with solid foods if they'll take it.

They look an awful lot like what I've seen in tidepools from Santa Barbara to Baja, Mexico (never been in/to a tidepool further north).

I have a query out about it to folks who know these things. I suck at IDing anemones other than the obvious clownfish host species.

It very well could be an Anthopleura sp., but it is definitely not Anthopleura xanthogrammica (the giant green anemone from western N. America). Way too small and they don't form clusters like that when small. There is an anemone here called the aggregating anemone (A. elegantissima) that "fits the description" a bit better--it's small, forms colonial clusters, and looks sorta like it. Obviously it's from the wrong part of the world and temperature though, so it's not that species either. :D

Thanks all for the input. Those anemones from the west coast of the States do look awfully similar.

Matt, it'd be brilliant if one of your expert friends/colleagues were able to ID this. I double checked with the shop this afternoon and it was imported from Bali apparently.

It's pretty Tom. How much is it?

At the current rate of exchange, about $70, but that's a bit deceptive, considering how strong the yen is now. It would have been about $50 a while back.

Wait a minute - is this for the tank or table?

:P

I'm starting to think I might pass on these. Without knowing exactly what they are, I'm worried that they will spread (credible, given that they are colonial and anemones are motile) and sting other aquarium inhabitants I want to keep. I'll give it another 24 hours just in case someone comes up with an ID, but probably ring on Sunday to let them know.

That's prolly a good idea Tom - you could always set up a nano or micro however and have them too!

Not a bad idea, but I actually caved and rang them today to lift my reservation. I rang earlier partly because it gave me leeway with my wife to buy a bit more on a trip to pick up a new chalice I'd reserved at another LFS. Came away with three new corals, which was a bit cheeky. :wink:
