Anemone ID question      4/16/18
<Greetings Frank>
I came across this rainbow anemone
<Umm; not rainbow naturally. This specimen has been artificially dyed. Do NOT buy it. DO read here: http://www.wetwebmedia.com/coloredanemones.htm
from a vendor and I’m not convinced they know what they are selling. They list it is as a Thalassianthus type anemone, but it kind of looks like a hell fire a little.
<Could be the former genus... the latter is just a common name that I've seen applied to quite a few species.>
Do you know what species this is and how big they get. This is about 3” and do you know if they are a fast grower? I do have various anemones (tube, rbta,2 rock, mini carpet) with fish and my fish are pretty good avoiding these without touching them outside my trio of clownfish in the rbta. Will this be a big risk for my fish since I had 0 causalities for years in an established 54 gallon tank?
<I would NOT mix this animal in with what you have. Again, I would NOT buy it period, as it has been artifically colored and is not at all likely to live; being bereft of endo-symbiotic algae>
Thank you for your help as always!
<Thank you for sharing. Bob Fenner>

Re: Anemone ID question      4/17/18
Hi Bob,
I just got off the phone with the vendor who hand picked this in Indonesia (<Omitted> please do not post his name thank you). He mentioned that he does not believed this was dyed and its the first time he came across this type of anemone.
<... I have never encountered such a naturally colored anemone as this. Am close to total confidence that it is dyed>
He said he had no issues with this place and he had been going to this place for years to hand pick. He mentioned it being as close to a bubble tip anemone potency vs. a carpet. I have seen dyed long tentacle anemones and leathers in the past. Usually its 1 color and nothing like this.
<Yes; agreed... or two, three colors... side to side, top to bottom... >
Also, he had a few different ones with green and yellow, but this was the only rainbow one. I'm stumped because it is an anemone that he reached out to various sources and could not identify. Enclosed is a pic that he just sent me. The red in it is not as intense. Thank you again.
<Dyed mate; and dangerous to put in your system. You may end up losing all... One last time, I would not buy this animal. BobF>

Re: Anemone ID question      4/17/18
Thank your advice. You just saved me a 1000.
Did you find it strange that the colors are different from the original.
<I don't find it unusual at all; red does fade more quickly; and take a close look around the mouth... colorless, and the various parts of the capitulum... Inconsistent; painted w/ a brush to dye it.

He said he had it about a month.
<Is the biz still owned by the original fellow; the <Omitted>? Unusual for him if so to make such a purchase, mistake. Bob Fenner>
Re: Anemone ID question      4/17/18

I believe so. I spoke to him directly. <Omitted>.
<Real good. Will not reveal his identity. B>

Anemone identification   3/21/18
Hello crew, I am hoping you can assist me in identifying 2 recent hitchhiker anemones I have received this past week. Both came on Zoa/Paly colonies/frags but from 2 very different sources.
As you can see both are small (for the moment at least), very similar in size to a Zoanthid. Both are green.
Anemone 1 has these striking green spots on it's 'stalk', and has actually moved a great deal since being added.
Anemone 2 (there are actually 3 of them on the same frag) has not moved at all. Someone has suggested to me anemone 2 may be a young Epycistis crucifer but I also wouldn't be surprised if it is something more 'pesty'.
Both are very aggressive eaters, but don't seem to have much of a harmful sting.
Either way I rather like them, I am mostly interested on your opinion of whether either is going to pose any problems for me in the future.
<The first... I swear I've seen something like this... w/ the spots of  different color on the pedicle; but don't see in my ref.s here. Have you gone through the many Anemone ID FAQs on WWM? The second, due to the relegation of tentacles to the edge, striations from the mouth, am thinking is another Zoanthid. Bob Fenner>

Re: Anemone identification     3/22/18
Thanks. I have started going through all the anemone id pages on WWM but haven't gotten through them all yet Haha
I did see one photo that looked like 'anemone 2' but couldn't find the enquiry that went along with it.
If I find anything I will let you know
<Thank you Nicole. BobF, injured>
Re: Anemone identification     3/22/18

Bob, I looked through all 40 some odd pages of anemone ID on WWM and did not find an answer.
<Ah; me neither>
I did see some very similar ones to anemone 2, most being called majano by your team, but I'm not convinced.
<Agreed; similar, but not the same>
Either way I believe it will likely become invasive so I will keep an eye on it.
As for anemone 1, nothing came up in the ID pages. I did post it to a couple saltwater Facebook groups and someone suggested Anthopleura xanthogrammica.
<Nah; we have this species and A. elegantissima off the (Calif.) coast; I did a histological study of the latter in college; and always look for the "Giant Green Anemone" when I am up the coast (gets much larger northward)>
After some further reading and research I think it is very likely to be an Anthopleura but I am more leaning toward Anthopleura sola.
What do you think?
<Lo dudo; this may well be an Actiniid, but A. sola is a coldwater animal found in about the same range as the other two congeners mentioned here; Baja Ca. and points northwest... It's a coldwater organism. Don't see how
it would find its way onto a tropical Zoanthid colony rock. Bob Fenner>

Re: Anemone identification     3/23/18
Ah ok, I guess it rules that out!
Maybe as the anemone gets bigger (if it gets bigger!) I will get a better idea of an ID by it's size and reproductive/colonizing behaviour.
<Let's hope so. I really like these mysteries. Cheers, BobF>
Re: Anemone identification     3/23/18

I forgot, I also wanted to share one more photo with you that I took last night. Since posting this photo on Facebook for ID purposes I have had 5 or 6 offers to purchase it! Haha.
<Heeeee! Again; I have seen this animal... Ugh. W/ the green spots on the pedicle. Am on pain med.s and feel like my mind should be like this when I'm like 99! B>

Re: Anemone identification     3/23/18
Sorry to hear that! Maybe it will come to you when you recover!
<Heeeee! You're bringing to mind my condition when imbibing and not. With alcohol I have a somewhat differing set of recall...! B>

Small Green Anemone ID      8/21/17
Hello Crew!
<Hey Em!>
We've had these small bright green anemones for some time now (hitchhikers from an encrusting Montipora rock). But they've started spreading rapidly at the start of this year. I initially thought they were majanos but none of the image searches matched ours.
<I don't recognize these either; they appear to be Zoanthids actually>
When poked, they retract rapidly, first deflating as flat as possible before curling in their edges.
They're such an incredible green (especially under pure blues) that the pictures don't do justice. Though if they keep spreading at this rate I will have to start culling. :(
Best regards,
<Thank you for sharing; and yes to keeping them isolated on their own rock/bommie/s. Bob Fenner>

Tiny white anemone id       8/9/17
Hi, found this anemone climbing the glass, translucent white with white bands on tentacles.
It is small about 1/4 inch when fully stretched out.
Should it be removed?
<Mmm; maybe... appears like an Aiptasiid... glass anemone. In too great a concentration/population can be problematical... in terms of stinging other life. OTOH, may be employed in a refugium as a nutrient exporter...>
Pictures from a usb microscope. Thank you. Tracy
<Thank you for sharing. Bob Fenner>

Re: tiny white anemone id     8/15/17
Hi Bob, Thank you for your knowledge! I'll move it to a spot where it won't bother anything. - Tracy
<Cheers, BobF>

Anemone identification. No pic       3/21/17
Hi! I’m new to the hobby, tank has only been running around 8 months. About a month or so ago I noticed two little anemones growing on some rock. They haven’t moved, split or caused any harm. I have tried to identify them but after contacting lots of forums and Facebook groups opinion is split 50/50 on them being either some kind of BTA or a majano. The advice on the latter is to wipe them out but I would like a more definitive identification before taking drastic action. I hope with your vast knowledge you will be able to advise me.
Thank you.
Brian T.
<Mmm; more likely Anemonia... or Glass Anemones... Do you have a photo to share? Bob Fenner>

Carpet anemones ID       8/11/16
Is it possible to please ID the anemone.
It came as a mini red anemone at a local pet shop but looks more pink.
shipment came from the US to South Africa.
There was no scientific name.
It's quite sticky like a carpet.
<...? Need a better pic... cropped, resolved. Have you searched, read on WWM Re Actinarian ID? Do so.
Bob Fenner>
Thanks Mohamed

  .... cropped

Re: Carpet anemones ID        8/12/16
I have searched but could not find anything close to it.
It's only about 1/2 inch.

The first thing that comes to mind is a Ric but it's very sticky.
It's the closest I could get based on the size.
Thanks for the help.
<Well; these are better pix... and it does look to be a Stichodactyla species... I'd LEAVE it at the shop till it expands a bunch... they should be treating it w/ Iodide/ate, perhaps some glucose solution and a thousandth reduced spg... and feeding it sparingly. Do you see elements of the pedicle? Any striations on the surface tentacle arrangement?
DO please have a look here: http://www.wetwebmedia.com/cptanemidfaqs.htm
and the linked files above. BobF>

re: Carpet anemones ID       8/12/16
Can't see any sign of pedicle.
It does seem to have striations.
<Then my guess is on S. haddoni. B>

Thanks Mohamed
re: Carpet anemones ID

Is it possible to tell the species of Stichodactyla?
<?! Yes... Don't write: READ>

Thanks Mohammed

Baby rock flowers? Or pests? Hard to make out      6/12/16
I have about 10 rock flower anemones in my 100gal aquarium. I know for certain at least one is make <?> because I have witnessed it releasing reproductive material. About a week ago I noticed two tiny polyps on this rock.
The polyps resemble tiny Aiptasia except they have shorter tentacles and a bright green center. Yesterday I noticed there are dozens of them scattered around the entire tank. I was finally able to collect one from the sand bed for closer inspection. It is still difficult to tell exactly what it is. I looks like a tiny rock flower but I was under the impression that baby rock flowers stay at the base of the mother until they are large enough to crawl away and I have a few of these little guys clear across the 100 gal long.
The one I collected into a Petri dish is VERY sticky. I touched it to see if it reacted like a rock nem and it stuck to my finger instantly. Here are the best pics I could get of the collected nem.
<Likely this or Anemonia. Bob Fenner>

nem? I.D.      4/28/16
I was wondering if someone could help me identify this animal. It appears to be some sort of rock flower nem, but is missing some of the normal features of a rock flower nem.
<Mmm; not this. Almost look like Zoanthids, but more than two rows of tentacles...>
They are about 1" across, do not appear to sting the corals around them, do not seem to "walk" around, and do actively feed on mysis shrimp and other frozen foods.
If you could help me identify them, then I can be sure that I'm giving them proper care. Thank you very much for your time!

<These appear to be some sort of Anemonia sp. to me. Bob Fenner>

Anemone ID... following directions?        11/23/15
Could you ID this?
<.... try retaking, and re-sizing your photo and re-sending. Is the pedicle red here? Smooth?
HAVE YOU READ on WWM? Bob Fenner>


Hi All.... myst. "coral"  bonus!      9/8/15
<Tab; twelve megs of pix? Groan>

I was searching for information on a mystery coral and came across your foram.
I just set up a tank to start cycling and bought a live rock that was taken from an old tank at the store. After getting it home we noticed what looked to be a whitish slime on it going to rinse it off i noticed it opening thinking we had a stray coral i just put it in my tank. It has recently opened more and i wanted to get it identified to make sure it wont harm any other coral or fish i will eventually place in the tank. it has only been in the tank for about a week.
These picture were taken within 20 min of each other
<Interesante.... in cropping, spiffing up.... this looks like a Haddon's carpet anemone..... striated; uniform tentacles as small bumps uniform over capitulum.... What say you? Bob Fenner>


Anemone Dream... ID, ?        9/3/15
Petco of all places has the most striking and healthy looking anemone I have seen in a while. He is labeled as a sebae anemone but his appearance doesn't seem to support this label. His foot is orange and large, bigger than his tentacles when he retracts.
<Perhaps Heteractis malu>

And the tentacles are knobby kind of inflated with rich tones of maroon and purple. Definitely not one suffering the bleaching effect. So I have decided to devote 1/2 of my available tank space to this guys future, that equals out to be a65gallon total volume. We have 2 Kessil 160s, the anemone side of the tank would run the pendant at full intensity to try and accommodate his needs. My tank tests 0 ammonia or nitrite, 5-10ppm nitrate, 8.2 ph, 480 ppm calcium,
<Too high. See WWM>
8 dKH, 1.025 salt content, 78 degrees F. I don't currently use any chemicals or additives unless you see something amiss.
<.... the universe is comprised of chemicals, vacuum, energy, and if you'd like to count it separately from chemical, free flowing protons>
I want to get him out of the pet store though so he doesn't begin to bleach. He is phenomenal in his appearance. Understanding that these animals are unique individuals this particular animal seems to have defied odds and I would love to provide him with a safe, clean, healthy tank. Your expertise is always cherished. Thank you.
<? See WWM Re? Bob Fenner>

Help with what this is..     5/10/15
I was told you could help.. I'd like to be sure not Aiptasia. I got live rock and hoping didn't end up with bad hitchhiker...thank you..
<Mmm; looks like a Glass Anemone to me... Do see/READ on WWM re Aiptasia...
Bob Fenner>

Re: Help with what this is..     5/10/15
Thank you for super fast response I will be taking care of this pest asap. .
<Ah, welcome. BobF>
