Doing what it takes to keep Anemones healthy long-term
by Robert (Bob) Fenner
Need help identifying anemone -- 03/18/10
I've attached three pictures of a strange anemone. It lives
in the sand at about the 10 foot depth, and is usually covered
with sand during the day (see picture #1), although sometimes I
can see it, especially in the late afternoon. At night it comes a
little above the sand and looks like picture #2. When my dive
light attracts a worm or small fish to the anemone, it closes up
as in picture #3.
These pictures were taken on Bari Reef on Bonaire, Netherlands
It is about 1 1/4 to 1 1/2 inches in diameter. Any idea of what
<I've been to Bonaire a few times... it is a treasure for
divers... but have not seen this beautiful anemone (though do
occasion Cerianthus in the shallow sands... in about the same
environment, quite often). I've looked in my references, on
the Net, and I can't place this animal. I would send your
images along to Daphne Fautin (Hexacorallians of the world .com)
in the hope that she might know, or be able to find you someone
who does. Thank you for sharing. Bob Fenner>
Mystery anemone? -- 3/14/10
As always, thank you for all your help.
Today I have a question about a critter that came into my life
through a macroalgae shipment (see attached picture).
<Mmm, can you tell me/us where this macroalgae shipment
originated? Looks macroscopically like it might be a temperate
species of the genus Actinia (tenebrosa? or maybe Phymanthea
At the beginning, I thought it was some sort of pest anemone (and
perhaps still is!), but I put it aside for later observation
The more I looked at it, the more I become taken by its
microscopic beauty, especially those lips and its playful
symmetry. Unfortunately, I still cannot ID it, and therefore it
has been confined to a little container in my refugium. Any ideas
on what it might be?
<Not with any confidence... though I do agree w/ you, tis a
Do you think it could be harmful to my reef?
<Possibly... if it proliferated, ended up too many, too close
to other sedentary invertebrate life>
grateful for your great service,
<Thank you for sharing. Perhaps someone will "chime
in" on posting this on WWM w/ a better ID. Bob
Re: mystery anemone?
Thank you Bob.
The macroalgae shipment was from Gulf Coast Ecosystems, an outfit
in Florida that aquacultures a great diversity of macroalgae and
harvest them from the gulf of Mexico and the Caribbean.
will keep looking,

Ask the WWM Crew a Question... A joke?
Can you help me tell what kind of anenome this is.
I got him a few days ago and sometimes he attaches and opens up
but most of the time he just kinda floats around
sometimes he looks like he is pulled everything inside and turned
into a little white ball. I have a 55 gallon tank with 2 clown
fish and him, also 10 pounds of live rock, 40 pounds crushed
coral. Canister filter. 1.024 salt, fairly new which i now no
was to early for anenome but... i did put a small piece of krill
on him and he grabbed it and am pretty sure he ate it.
Does he look healthy???
<... are you joking? Have you searched on the site/WWM
Just need to know what kind he is so I can do better research and
try and make him happy.
<Should have done this/that ahead of purchasing this animal...
|Re: Ask the WWM Crew a Question
Not very helpfull bob. "dying" does not tell me what kind
<Am hoping this/it will spur you on to investigate
Also, now I know I should have researched first.
Fish store (Petco) person asked me what some of my levels in my
tank were and said it would be fine,
I was only there to buy 2 clowns. I NOW know this to be wrong! Just
trying to do evrything I can to help him survive. And what do you
mean by <... are you joking? Have you searched on the site/WWM
>Am/was really wondering. Who would send such a ludicrous
message, really? I thought you were trying to pull my/our
I have looked some more and think he is a seabe. I just took new

temp 78 amm.1 kh 240 gh 180 no3 60 no2 1. All I wanted was a FOWLR
should I just "get rid" of the Anenome.
<Is that a question or a bald statement?>
<Again, are you serious? Show me evidence of your working
here... fill this room w/ your intelligence. B>
Re: Ask the WWM Crew a Question 3/8/10
Ok maybe asking you guys thes questions was a mistake. Obvisouly I
am not at very knowledgeable about any of this. Like I said earlier
all I wanted was a fowlr tank. The pet store said the anemone would
be fine in my tank.
I was wondering if I should try and give it to a better locally
owned pet store here that specializes in fish.
<I would return this animal to Petco>
I have done a lot of research over the past few days And found out
my tank is way to <too> new for anemones. Only five days
<Too soon for most any/everything>
two clown fish seem to be doing fine. if there is anything I can do
to save him I will otherwise I will try and give him away.
I really appreciate any help In this matter. I have also signed up
for a class on marine aquariums at my community college.
<Ahh, very good>

Re: Ask the WWM Crew a Question 3/8/10
Already called petco they have a no return policy.
<Mmm, I think the law in every State in the U.S. says otherwise.
Ask to speak with the store mgr., and if they won't comply, ask
for the Regional Mgr.. And if not them, call corporate in San
Diego. You are welcome to mention my name. Really>
The local store where I got the clowns said I could add two fish
every month. Does this sound right.
<No my friend... best for you to peruse a good general book on
marine aquarium keeping. Martin Moe's re-do is recently out.
Re: Ask the WWM Crew a Question 3/9/10
Thanks, ordered the book. Will stop everthing till I have read that
and finished the four week course.
<Outstanding! Be chatting, BobF>
Heteractis Malu Or Heteractis Crispa/Anemone ID
Love your site and books!
Great resources, I'd be lost without them.
On to the anemone.
I thought it was a Crispa, but after reading your Malu section
there were some similar pictures to mine..... Now I'm
Is it a Heteractis Malu or Heteractis Crispa?
<After looking through Mr. Fenner's anemone scans, it
looks more like a Magnifica/Ritteri (photo attached), and a very
difficult specie to keep alive for any length of time. Mmm, what
color is the column?><<Mmm, am pretty sure... 95%
confidence limit, that this is a H. crispa here. RMF>>
<You're welcome. James (Salty Dog)>
|re: More re: Heteractis Malu or
Heteractis Crispa? -- 3/3/10
Thanks Bob, looked like a dead ringer compared to one of your
Magnifica photos. Looked like the Crispa has longer, slightly
thinner tentacles in comparison to the Magnifica, but I'm not
going to argue with experience. What traits led you to your
ID....very interested to know for future reference.
<Mmm, Magnificent's don't have "pink tips",
but do agree that for a leather, this specimen has a BUNCH of
tentacles. Cheers, BobF>
Re Heteractis Malu Or Heteractis Crispa/Anemone ID
It is all the same color through out, a beige brown with bright
tips on the tentacles. Its attached itself to a rock very well and
hasn't moved yet.
<After talking with Bob re the ID, he would bet his last beer
that your anemone is a Crispa. It is unusual that a Crispa would
prefer anchoring to the rock rather than burrow into the sand,
unless it just appears to you that he is anchored to the rock.
The giveaway in ID'ing was that Magnifica's do not have
Regardless, Heteractis species are difficult to maintain in captive

mini carpet anemones, ID, pests?
After Googling many pictures, I think I got what appears to be a
mini carpet anemone as a hitchhiker on a rock about 1 year ago,
but now they have multiplied like crazy.
<Really? Unusual. Can you provide pictures of these? I doubt
if these are Carpet Anemones, which are quite large animals:
I have about 10 or 12 on all different pieces of rocks, they are
very small, maybe the largest one measures
about 1 inch in diameter. Are they pests?
<Depends on what they actually are, and your point of view.
Are you sure they are not Aiptasia?
Should I get rid of them or are they OK to have?
<If they are a pest Anemone, then no. They will sting your
other sessile invertebrates>
I have a 75 gallon tank with live rock, different soft corals and
some fish. I did a search on your page but it did not say
anything about them multiplying.
Thank you for your help,
Re: mini carpet anemones 2/24/10
When I looked it up, it said it was a "Stichodactyla
<Really? And these are multiplying? That's great, really
Please send us a photo/s so we can post it in our
FAQ's><<We have such. RMF>>
I don't have a camera but I found a picture of one in
<Yes, can't use this I'm afraid>
and I also read another person asking about them, but I don't
know if I should just let them be in my tank or if I should get
rid of them.
<It's up to you Erika. With such a great little hitchhiker
I would be temped to let be and remove other cnidarians if
necessary. Are they causing a problem? If not, then just leave
Here is a link with info about them, do you know them and why do
they multiply so fast?
<Thank you for this reference, Erika. As far as 'why',
you are obviously providing them with what they need. I believe
they are easier to care for than most Carpet Anemones, which are
quite demanding, and this is good (or
Thank you for your help.
<No problem Erika, thank you for writing, and do try to get us
a couple of shots of these!>
Re: mini carpet anemones 3/1/10
I am attaching several pictures of the mini Carpets, I'm
afraid the pics are not that great, but the Anemones are quite
<Yes, I can see and thank you for these!>
So you don't think they will be harmful?
<Yes, they can be.. they have powerful nematocysts like all
Anemones.. but like many things it is a trade-off as to what you
prefer to have. I do think that they are far more beautiful and
interesting than the brown Zoanthids you have in the same
picture, so if I had to choose between these for example, then
I'd pick the Anemones>
I don't feed them anything specifically for them, so I guess
they get their food from the system. <Yes> I have other
"soft" corals so that is why I thought they could harm
them, but so far they don't seem to be causing problems, I
just got a little nervous b/c they started to pop up all over my
<Mmm, they might do in the future>
I did notice they started to multiply after my Fluval canister
died. I had read about systems w/out the canisters and was afraid
to risk running my 75 gallon without one, I do have live rock and
live sand, a large hob refugium with macro algae and a Remora Pro
protein skimmer. So when my canister died I decided to try it
out, its been about 3 months since then and the water parameters
are very good and the water is very crystal clear so I guess all
that "read" is right. Do you think I should worry about
<No, I only use canister filters on quarantine systems myself,
not on my main system>
My only concern is that I am not running any carbon to get rid of
some of the "chemicals" from the corals, what do you
<I would, but if it ain't broke...>
Thank you so much for all your help and for the wonderful
<No problem, but I've not written any books myself! Mr.
Fenner is the one for that, and I believe he is writing a new one
as we speak... about small systems and being serialised in
Ultramarine Magazine at the moment>
Many blessings to you,
<And to you and your Anemones, Erika, and thank you for your
Stichodactyla tapetum. RMF
