Doing what it takes to keep Anemones healthy long-term
by Robert (Bob) Fenner
Attn, Bob... Report: Dyed "Sherman Rose" BTA!
Hey ya'll, Sean Morris, down here at Acadian Mariculture (what I am now calling
my marine breeding operation, hehe)...I was trying to make my true perc
broodstock happy because my last two clutches weren't... well.. alive
for long...and so my LFS who I do a LOT of business with, had these beautiful
"Sherman rose anemones" ... purple disk, dark brown base, pink tentacles no
green showing at all. I recently recovered a bleached gbta from
there, so my water quality isn't a problem... again... I breed true percs.So my
wife bought one... and it hasn't been doing well (thought it was due to quick
acclimation)... so I went and bought another... did a 3 hour acclimation...
brought it home in an ice chest...bought two gbtas with it...-I want my mama
percula to imprint on rose and regular so the babies will take to both. at least
that was my plan-Well... today, after waking up to the three new anemones
looking perfectly happy... ... this first Sherman is still showing the same
symptoms:-tentacles sticking together, sticking to algae, bacteria.-overly
frequent defecation of body-colored bits.-enarging at night with mouth
open-color fading, turning white in some spots, brown in others-as sensitive to
hands in the tank as a ritteri(whereas most btas, you can touch and they don't
care, this one shrivels when I pull have a finger in without vinegar soaking,
and even then, its only a matter of time)-and now, today... a green tentacle.
just the one?
<Mmm; they can/do change color/s at times>
A single green nub, surrounded by pink and purple... cant really see it well in
the photo, but I tried. one green tentacle...for now...but the bleached areas
seem to be showing a little green, as well.i will more closely document the
progress of the other, formerly identical, specimen, and post progress on my
YouTube channel, The Lost Begotten. Feel free to check it out ;)-also filming an
ultimate anemone guide series, so you may find that helpful.
<Oh yes; my pitch/presentation this year (August) at MACNA is titled Captive
Anemone Use. Do make it known when and where this is posted>
In addition to my 30yrs exp, this past weeks panic has made me update my
research-base, and I feel like I've got some complete info that needs sharing.
For now, I had to let you all know about this, apparently, dyed RBTA...
makes me wonder if Sherman's are all dyed. It would be sad, but not
surprising, if con-artistry had become so elaborate.

Rainbow BTA not doing well after tangling with Bristleworm
I have a 29 gallon,

One day about a month ago I woke up to find some bristles stuck in her.
She was deflated, disc shaped, I removed the bristles and hasn't
since. She is getting smaller and eating less each day. We try to feed
her krill and shrimp but she isn't really interested.
<... how small are the pieces?>
Now she has moved about a half inch closer to the light and will react a
small amount when the lights are on.

do educate yourself>
<Welcome. Bob Fenner>
Re: Rainbow BTA not doing well after tangling with Bristleworm
Sad, since LFS and online forums have told us all of these were fine
together in a 29 gallon.
<... I do understand. Take a look where I've referred you; or see my
book on captive husbandry of Actinarians... or catch my pitch at this
year's MACNA... on the same topic>
We have tried various sizes of food ranging pea sized to grain of rice
size and she rejects all food.
We have a 75 gallon in the works but that is a couple weeks off before
we can begin the cycle. I will move the frogspawn to another tank is
there anything else that can be done?

Is the Acan bad also?
<Not as much so; no>
Also I forgot to mention a small sun coral
<Tubastrea likely; also moderate. B>
that is also in the tank. Thanks for the link.

Anemone Behaviour... Cause? 2/28/17
I have a 60g tank with 3" aragonite bottom, 55lbs flat live
rock for eventual coral placement, protein skimmer, 2 x Kessil 360's on 9.5hrs
(1.5hrs are 5% intensity blue lights, that ramp up to 60% intensity), 78F, 1.025
salinity. I have two pumps circulating my filtration chamber at 10X/hr, and I
have an MP40 on 40% power a variable Nutrient Export setting
that switches up the flow every 45mins (this adds another 27X/hr flow rate). The
tank is 3months old, and my store had a rose bubble tip anemone that had
recently split and was selling the new addition at $40 which I thought was a
steal so I bought it two weeks ago.
<Mmm; a comment here for all would-be anemone keepers: Better to have "more
seasoned" (older, established settings) than newer>
My water parameters have always shown ammonia/nitrite/nitrate at 0;
<Oh! DO need some (measurable NO3, AND P and K....); anemones are chemosynthetic
to a large degree>
given my hair algae I perceive I have a little nitrate/phosphate that's feeding
the hair algae but still shows untraceable amounts. I've read through your two
main articles on BTAs, and I'm curious about the 7-14 day feeding
regimen recommended there. How much for a small BTA?
<Twice a week... let's say, meaty food equivalent (bits) of half your last pinky
segment in volume>
I have purposely let thawed mysis or brine fall on the BTA's tentacles and it
doesn't seem to draw the pieces in. I've seen my Percula Clown bring the BTA
food. Not sure what the BTA is supposed to look like feeding. I should
point out the BTA moved about 5" over night from my original placement and seems
to have secured itself under a ledge in a lowlight area.
<Good; don't move it>
If the BTA were to move above the ledge it would be in a very will lit area, and
I'm assuming that given it hasn't moved since day #1 that it is happy where it
currently resides - otherwise it would move?
<Needs chemical nutrients; remove your chemical filter media (if using) and turn
your skimmer down or off for half the day>
Three days ago, my BTA looked like this (picture attached), about 45mins later
it looked normal. First thing this morning, my BTA looked like this again.
Someone on a forum indicated this was normal behavior, but I wanted to ensure
this was the case.
<They (Actinarians) do expand, contract to degrees>
Given my clown is over half the size of the BTA, I was curious if the clown
might be harassing the BTA too much? Thoughts?
<Mmm; not this species.... the smaller clownfish are generally not trouble in
this regard. IF you see, expect otherwise, place the clown/s in a floating
plastic colander for a few days... see if this helps. IF it continues, fashion a
plastic mesh over the anemone (straw- et al. berry baskets work well here)>
In particular, I'd like to know how much food is appropriate on a one or two
week direct feed schedule. I also feed my tank Oyster Feast and PhytoFeast (one
of them) twice a week for the feather duster, colt coral, star polyps,
<Oohhhhh; the soft coral, Clavulariid and/or Zoanthids... may
well be winning a/the chemical allelopathy war here. Do you have another
established system you can move the Entacmaea to? I would. Bob Fenner>
Re: Anemone Behaviour 2/28/17
I should add, the star polyps are upper tank range and a good 18" or more away.
I have three small heads on my Zoa frag that is nearly two feet away. The colt
coral is at the opposite end of the tank almost 3' away.
<Uh huh... notice I wrote "chemical", not physical... they don't have to
be anywhere near; just in the same water. Have you read my piece, ppt
on avoiding Cnidarian warfare? My bit on "Boris Karloff-ing" by mixing water
to/fro...? See here:
I would say the coloration of the BTA has, if anything, improved since my
acquisition showing deeper red and greens. Aside from this 'enclosing the
tentacles' behavior that I am unfamiliar with, I'd say the BTA appears to be in
great shape. I guess my question was regarding feeding, and if the 'enclosing
the tentacles' was normal. Am I correct in saying the 'enclosing of the
tentacles' occurs for either feeding or protection perhaps while sleeping?
<Seems to be all unrelated... Night dives find them mostly open.... just when
the current or too brisk, or something is physically bugging them do they close
in the wild>
Yes, I had read 6months or more in an established tank for anemones; however, my
soft corals have been doing excellent and I'm a fanatic over water changes and
keeping my tank as pristine as possible.
<Do you attend the MACNA do's? My pitch (okay presentation; better connotation)
this year (August, in New Orleans) will be on Anemone Use in Captive Settings...
I have a short book w/ about the same title as well.
See Amazon re. Bob Fenner>
Re: Anemone Behaviour
I will for sure have a read and add your book to my "Fenner collection".
<Heeee! Yours is likely larger than mine!>
Chemical warfare, right... but yet I hear of so many people that successfully
keep both and in smaller tanks.
<Yes; just need to be "properly introduced">
On your BTA anemone section of the website, you also have two articles from
other writers who were guiding me to the every 7 to 14 days for feeding.

ID. Entacmaea, torn, leaking pedicle/foot.
Hey guys, several of us were wondering what this blue clump is on the bottom
of this Bubbletip anemone. Was seen by a friend at a shop. Sorry I
don't have any more info.
<Yikes, and thank you for sharing Lori. This is part of the animal's
"mesentery" coming out from a torn foot. VERY/TOO common; occurs when
they're removed from the wild most often... from too hard and fast pulling,
jabbing at the animal's base to remove it from hard substrate.
Almost always a harbinger of doom for the specimen. I mention this
in articles on selection, oh, and a book (on Amazon) re Anemones, use in
aquariums. Please begin reading re here:

question regarding bubble tip anemone
I am writing in order to see if I could get some guidance/help regarding mi
bubble tip anemone.
I currently have a Boyu TL550, 130 lt, saltwater aquarium.
I placed my E. quadricolor 3.5 months ago, and for the first 2 months she did
great (I am attaching a picture from when she looked healthy).
Since 3-4 weeks ago, the anemone has progressively lost her
''bubbliness'', and the tentacles have ''shriveled'' and look flaccid and
''thin''. The colour has also changed; from a bright orange, to a
darker orange-brown and some sectors even look greenish. 1-2 weeks ago the
anemone decided to close (similar as when lights are off), and has decided to
stay like this for days. Today, she opened, but after 2 days of being closed. I
Ocellaris clownfish, the female resided in the anemone, the male resided in
<Aye ya... here's some trouble>
Now they have both moved to the Euphyllia, however the female goes back to the
anemone any time she exposes her tentacles.
I have never fed the anemone, except for 2 weeks ago (she was
already looking shady) with a mix of brine shrimp and saltwater and squirted it;
there was no change.
<Needs to be fed two, three times a week>
I have checked my parameters, temp is 24-25 C, pH 7.9-8.1, density
(they are pretty steady). I recently got more parameters, and the only parameter
that was not right was nitrate (20 ppm). Nitrite, ammonia, phosphate, calcium,
dKH were ok.
<? Meaningless w/o actual data, numbers>
The rest of the aquarium looks fine (other residents are Rhodactis, Kenya tree,
Parazoanthus gracilis, 2 Ocellaris, Sixline wrasse yellow watchman goby,
Salarias fasciatus, 3 hermit crabs, 3 snails, 1 Lysmata amboinensis).
If you could guide me in this issue I would be most appreciative.
<Well; as stated above; the Euphyllia is winning here, the Entacmaea
losing (allopathically); this animal is starved, and the environment? Did you
review BTA Health on WWM? All this is gone over and over... As are
suggestions for improving the situation... moving the Caryophylliid or
Actinarian (they need to be in sep. systems); foods/feeding... and
improving the animal's world. Bob Fenner>

Anemone Alerting 10/23/15
So I am sending this just prior to attempting removal of what, I fear,
is a doomed rose bubble tip anemone.
<Mmm; does look bad.... bleaching, losing integrity; though not quite
decomposing just yet.... this last can occur quite quickly, w/in hours>
He was a special order from my lfs. He seemed healthy in the dealers tank for a
month prior to purchase. Should he be removed immediately?
<Tough to state. I REALLY don't like giving up on life... IS there somewhere
else (a holding system, separate) that you can place this animal?>
The lfs told me they feed him krill
<... dismal. See WWM re BTAs>
and that he ate regularly. He has only been in my tank for 24 hours. He was
acclimated then he moved to the spot in the picture, under a rock. I don't want
to jump the gun but I had a disagreement with the seller because I
thought the animal looked bleached.
They insisted to the contrary that rather it was merely a lighter colored rose.
To their defense he didn't gain or lose any color, but consistently "not rose".
He is anchored in the rock but has some slimy discharge, I think. Is this a
<Won't state a third time>
I admit I felt pressure to purchase because they don't stock the rose bubble
tips. Will it detach from the rock if it succumbs?
<It'll dissolve off>
Should I remove the entire rock right now? The tank parameters are stable but I
don't feel comfortable enough trying to recover a sick specimen. I don't want to
jeopardize the other inhabitants. The pictures aren't good but perhaps you can
give me an idea.
Bubbletip Anemone Adjustment 9/5/15
As usual I have read and reread the online facts but find myself concerned about
the appearance and subsequent care of a rose Bubbletip anemone. He was added to
a 65gallon reef aquarium last night,
<Is there, are there two anemones here?>
drip acclimated over about 75 minutes to my tank with stable parameters of
1.025salinity, 0nitrite and ammonia, less than 10 ppm nitrate, 8.1 ph, 8.5dKH,
440ppm calcium, temp is 78 degrees F. He was attached to a rock at the store and
is currently tucked into a rock crevice in my tank, with a devoted anemone crab
in tow. He is mildly sticky when touched and did consume a bit of shrimp that
his crab commandeered for him. His mouth isn't open or sagging and he doesn't
have any discharge. Yet he appears, well, unusual, his tentacles are short and
stubby. I assume he is stressed but want to allow for his optimal adjustment. So
I have 2 (Kessil 160) leds and was wondering about appropriate lighting
intensity and period, 20% for five hours for instance?
<.... s/b fine to start>
I was prepared for him to be active in choosing his location but he seems to be
rather passive. Is his current appearance any indication of his tolerance of the
Will his tentacles stretch toward the light if he isn't getting enough?
<Not when new to the system; no>
Obviously bleaching is a worst case, best avoided scenario, he came from rather
weak high output fluorescents for a couple of weeks. I brought him home "early"
because I feared the fluorescents would be inadequate. I have owned anemone in
the past and this goofy kind of spread out but not extended look is unfamiliar.
Your assistance is invaluable, thank you, and I will continue to read
<Again; your one pic shows another anemone present...or Scleractinian too close
by... higher up.... Not a good idea to mix specimens (unless they are
clones); though this can be done. Do use the two words: Anemone, allelopathy in

re: Bubbletip Anenome Adjustment... using WWM
I am responding back to you with hopes you will also view my original email in
regards to the system my bubble tip anemone is in.
My question is that the anenome <Anemone> will not attach to either rock
or substrate but it also doesn't move, at all.
<Likely its foot is damaged. Have you yet read on WWM re Entacmaea? You need to
I want to know if there is any method to try and coax it to attach? I am aware
that they tend to migrate to seek ideal conditions, could mine be so weak that
it is incapable of relocation? At this point I would love to see any sign of
life, he looks exactly the same as in pictures. And he is the only anemone.
Should I increase the intensity of the Kessil lights, as suggested they are only
at 25% output for a 5 hour period. Indeed I am perplexed by his behavior, he was
attached to a rock when purchased but easily withdrew and wasn't torn or
injured. Your input is welcomed. How long does he get to hover around before I
fear the worst? He is going in to his second night?
<.... have just skipped down. READ here:

Bubble tip Anemone Fate.... not a reader
Your website is a tremendous resource and I will continue to try and
learn before I ask. I have a rose bubble tip anemone though that I
purchased three days ago. I was concerned about an injury to it's foot because
it does not attach or move about. I didn't want to further stress the animal
with examination but if you think he has had enough time to acclimate (to my
tank) then the lfs has offered to take the anenome
back. I am certain in it's fragile state it would not survive another
move but am my wits end and I can't seem to figure this guy out. I have attached
a picture of his daytime look. The other picture was taken from above with his
foot out to the left oriented kind of sideways, after lights go out. His foot
appears not to be smooth but rather warted with a slight protrusion out the
exact middle of the bottom of the foot. The protrusion doesn't look ominous, not
stringy or sloughing just bubbled? Should I, in your opinion, return the animal?
<You don't know what you're doing; won't read.... Return it>
Can acclimation to my system take longer than a few days? There has not been any
significant change either in behavior or looks but I can't say whether it is
teetering on death or getting used to a whole new world. It isn't withered or
shrunken but it also doesn't puff up and move about? My tank parameters are
adequate to support this animal but not if it has a fatal wound. It's in a 65
gallon, 1.025 salinity, 0 ammonia/nitrite, 10ppm nitrate, 78 degreesF, (2)

bleached anemones and lighting... Nine
megs of pix; photography-revelation
Hey guys, just wanted to send a quick note to you guys and thank you for
your website. I recently ran into an issue however and wanted to share
my experience. So first off some background about my tank.
125 gallon Reef Ready custom tank and stand with built in dual stand
overflow and a 50 gallon sump/refugium Orbital Current LED lighting with
Ramp controller Two Hydor Koralia power heads, a 3 and a 4 Reef octopus
XP3000 Skimmer PH 8.0Salinity 1.025Ammonia, nitrites, nitrate,
all 0 ppm
100lbs liverock various fish RBTA
I had just recently purchased a RBTA for my tank and when it arrived it
was very very small. Less than an inch across fully extended. After
doing the normal acclimation process for it and placing it in the
tank on the liverock. It chose a comfy spot about three inches from
where I placed it and settled in. It has been in my tank for about two
weeks now and has opened up and was showing great signs of health.
Eating well, lots of tentacle movement and extension, the whole bit. I
started to get worried when it seemed like it looked a little pale in my
tank. I wasn't sure how long it really looked that way maybe from the
moment I placed it in the tank. So I started doing research on bleached
anemones. Paid very close attention to pictures of what that looked
like, and asked advice from a few people on local reefing forums here in
my area. I worked myself into a frenzy over this idea that my anemone
was bleached and I needed to do something about it and keep vigilant
with feeding and other recommended steps to nurse it back to health. I
had taken a picture of the anemone and sent it to a few people and all
agreed that my anemone looked bleached and this was a critical time. The
first picture is what I sent, and received confirmation of a bleached
anemone diagnosis from several "experts". For more than three days I
wracked my brain over my bad luck. Including right up until an hour or
so before writing this note. Then it dawned on me...
The camera I had been using had the flash turned off from the last time
I used it. I turned it back on and took another picture of it with the
blue turned down to 10%. The second picture shows the actual anemones
coloration and overall health. The blue and white mix lighting each at
100% was playing games with my camera's color saturation and was skewing
my viewpoint of the anemone, and apparently everyone else's as well.
<Well; photography... is... about controlling light>
So there really never was anything wrong with my anemone at all. I
allowed myself to be fooled by the camera and my own eyes inability to
properly discern the anemones true coloration due to the over saturation
of certain wavelengths of light being emitted by the blue in my
So long story short.... Lesson learned. Just thought I would pass this
information along and hope that it helps someone else to properly
diagnose whether an anemone is actually bleached or not. Never trust a
single picture and sometimes even your own eyes to give accurate
information. I see tons of pictures of bleached anemones online all the
time, now the
first question I will ask if I am ever trying to help is, was the flash
on your camera turned on when you took the picture? What percentage of
blue was your lighting set to when the picture was taken.
<You've "traded" (filtered, screened) one part (bandwidth) of visible
EMR for another...>
Have a great day... Keep up the good work with the site.
<Still bleached, but thanks for sharing. Bob Fenner>
BTA question.... scarce data, no rdg. 7/13/14
<Katelyn; your files are an order of magnitude too large>
First, I apologize if you have already answered my question on your
website. I tried searching through the almost overwhelming amount
of information and I did not find anything
that seemed to answer my question.
I have a 90 gallon tank whose temperature averages between 77-79F and
the chemistry is at the appropriate levels (0 nitrates,
<Trouble... chemophotosynthates like Anemones NEED measurable NO3,
this is gone OVER and OVER on WWM>
nitrites, ammonia; little to
no phosphates, slightly lowered carbonate levels but good calcium
<... data; not subjective statements please>
At the time this problem started, I had a Picasso
clownfish, a Carmel Percula, 2 peppermint shrimp, 2 emerald
crabs, a large number of various snails, and a
BTA (who hosts my Picasso clown). I have
since doubled the amount of live rock in my tank and added a flame
I got my BTA about 6 months ago and until ~4 weeks ago it looked great!
It doubled-tripled in size and looked
beautiful (bubbled tips, nice color, etc). I
put it in my tank and it has never moved since. However, ~4 weeks
ago I noticed when I was home during the day that my anemone
would stretch from it's hole up toward the
surface and then every night settle back into
its hole (see attached pictures taken a few days ago). I have also
noticed more recently that the ends of the
tentacles appear twisted and 2 of the
tentacles have shrunk down to almost nothing. Color still looks good
though, the mouth is still normal, and it hasn't moved. Nothing
had changed in my tank when the weird behavior
started (or within 3 weeks of it
persisting)- same lighting (green element evo quad led), same fish, same
filtration, etc. I had a few days of temperature swings and
fluctuating carbonate levels as we went into
summer (my first with this tank) about when
this started, but I have since worked it out and the anemone is still
acting strangely. Any ideas as to what may be the problem? I
think perhaps lighting but why would it
suddenly become a problem now and not 6 months

Re: BTA question
I apologize in my ignorance in not connecting my anemone's symptoms to
that of malnutrition.
<? No apology necessary. And the statements on my part are only guesses>
A quick follow up- WWM is the only place I have seen that
states a benefit to nitrates and phosphates for
anemones, most other sites
state "none" is the preferred state. What is the
definition of "measurable"
from your previous response?
<A few ppm for NO3... a few hundredths to a tenth for soluble phosphate.
How to put this; these animals are like plants in your yard... suffer
for lack of essential nutrients... N, P, K...>
Is there a certain level I should be aiming
<Yes; gone over... higher 300s ppm to mid 400s>
I assume there is a certain threshold at which point the levels are
detrimental and it presumably is fairly low.
Or if there is an article somewhere I have
missed I would be happy to read it for the answers
<Do give the search tool (on every page) and the indices a go>
PS: Here are the numerical values or chemicals in my tank that were
from the last email.
<A bit high>
dKH- 6.7 (I'm aware this is low and have been using buffer to raise it.
I just can't keep the levels high, it seems to
fall within 2-3 days. Working on finding the
best schedule to sustain appropriate levels.)
phosphate- 0.25ppm (perhaps less, the kit wasn't too clear)
Nitrate/Nitrite/Ammonia- all 0ppm
Re: Clownfish Obsessed with new Feather Duster! Now; BTA
Good afternoon Bob!
<Ah yes; Amber>
I wanted to let you know that the Bubble tip anemone shipped in this
week and I have him in quarantine. What an awesome
creature. He didn't look very impressive to start, I was worried, but he
has bubbled up and looks like he is starting to get comfortable. My
question comes in regards to their guts. I have never had an anemone and
know that they exhibit some interesting behaviours.
<Ah yes; oh, BTW have just published a new book on them; e- and print...
I have been reading Lots in the archive as I always do, and though I can
tell you he is definitely going to be an amazing addition, the shipping
was rough and he still hasn't pulled is 'guts' back in( arrived
wed, acclimated well to qt)... at least that's what I am believing they
are based on what I have read, the difference in what I see though, it
isn't stringy... but like a
ball of white held by a few stringier filaments.
<Yes; mesentery, mesenterial filaments>
His mouth was closed and still the white ball of gut sat there, i
thought... it wasn't attached and used a turkey baster to gently blow it
to see if it was attached. It is... and now I think he is pissed (not
obviously, lol). Is this something he will die with out, it seems to be
trying to release it, not pull it in... I am trying to just leave him be
and be patient. It is very difficult and I am sorry for the new Question
Bob! Thank you again for your time. :)
<Hopefully will rest up, do fine... wait a week or two and start moving
water from your main/display to acclimate the BTA to the system... and
some vice versa. Bob Fenner>
