Long tentacle anemone 4/14/19
My long tentacle anemone finally came out of hiding.! Thank you for the advise.
<Ah, good. I do hope it reincorporates zooxanthellae... Bleached specimens don't
live long or well. Bob Fenner>
Re: Long tentacle anemone 4/15/19
Yes i hope so also. I've been trying to give it food small bits of scallops.
So far no luck but i am missing a baby (1") blue tang . And the nem was closed
up at the same time the tang went missing. I think some zooxanthellae have
returned. Hoping for the best...

I picked up a green LTA the other day.
<Oh? Your system, water quality, tankmates, history please>
Brought him home and did a 30 min acclim and slow water add. I put it in
his new home and it attached to a
piece of rock. Over the next few hours it moved down to the sand and
attached to the bottom of tank and has stayed there. The next morning it
retracted down to almost nothing and about 3 hours later it had refilled
and looked normal. Then again last night it did the same thing and this
morning it is back to looking fine. Is this normal?

I recently added a long tentacle anemone to my 200 gallon FOWLR.

Had read a bit ( not too much to be honest) and found nothing against
having them with tangs (I have a yellow and a hippo)
Hope both my tangs would be safe with this new creature.
Ever since I introduced this to my tank, it hid itself inside a rock
structure. Only the tentacles are swaying from the either side and the
entire body is hid between the rocks. Its been like this for the past
40 hours and has me worrying.
It was in the open during the night (when the lights were off). As soon
as I plugged the lights on, it moved and attached itself to a live rock
and eventually buried itself inside the structure. Surprisingly, it has
attached itself to the rock ( and not the base sand) and is a bit

Re: Anemone hlth. 12/13/10
Thanks for the prompt reply Bob.
Feeling much better now.
The anemone is still upside down but the base of the anemone firmly
attached to the live rock. It moved on to one side to expose the body a
bit but unfortunately at the back side where the flow is greater. Major
portion still within the rock cave. It has still not regained the color
(as it was in the store) and now looks bleached except for the tips
which are greenish in color.
I cannot see the mouth to give the description.
The tentacles drop down like shrunk skin at one moment and then look
full and with life the next. Totally confusing.
What symptoms should I look forward to make a decision in time.

I need to know whether this thing is actually : settling in" or
getting worse. I do not want to pollute the tank any which ways.
Thanks and regards
Long tentacle anemone curled in ball... Killing, sans
I have a question about my long tentacle anemone I just bought
yesterday from my LFS and was wondering if someone could help me. When
I bought it, it was about the size of a large saucer plate and had a
brown color to it with slightly purple tips. When I first acclimated it
to my aquarium it was doing fine with it's tentacles swaying in the
water and the same color as when I bought it. It might have moved only
about 1/2 inch from where I initially placed it on the sand bed, dug a
small hole, and attached itself to the sand bed. I went to bed and when
I woke up the next morning I noticed it had shrunk up into a purple
ball in the same spot. There was also some brown mucus looking stuff
hanging on one of the rocks. I imagine it expelled this overnight. I
thought it might have died overnight but I keep checking on it and it
seems to be expanding back to it's original size a little, although
still very purple in color and small. I haven't tried feeding it
yet but thought I would try a small piece of squid soon. The only other
thing in with the anemone right now is a maroon clownfish.
<Mmm, may not be compatible... Premnas can be tough on
To tell you a little bit about my aquarium, I have a 46 gallon bowfront
aquarium equipped with an Aquamedic Turboflotor 1000 multi protein
skimmer, a Fluval canister filter, and a heater. I'm not sure of
the brand name of the heater but right now I have it turned off because
my house stays warm during the summer
<Turn it on, set it on low...>
and the aquarium water is about 83 degrees Fahrenheit without it. The
aquarium is also grounded.
<See WWM re such probes>
I'm a little confused to the kind of lighting I need.

I've only ever had a marine all fish aquarium before for about 3 or
4 years. I got behind on the water changes whenever my son was first
born but now he is 16 months old and I wanted to start my tank up
again, this time adding some anemones and maybe corals to it. Right now
I have one OceanSun 10,000 K fluorescent bulb over my tank.
<... this is insufficient. You didn't read, either before buying
this animal, or writing us... >
The light is only 25 watts and it kind of confused me as to why it was
so low being that I read that you should have about 2-3 watts per
gallon of aquarium water. I'm assuming you're supposed to
install more than one bulb but right now my aquarium hood will only
hold one light unless I upgrade.
The light also says that it promotes the growth of Zooxanthellae
There is a mixture of sand and dolomite in the tank with some Tufa rock
(I have no live rock in my tank yet) and I use well water with stress
coat added. I also added Kent marine Superbuffer -dKH to the aquarium
about 2 days ago. The salinity is 1.022,
<... too low>
pH is 8.3-8.4, Ammonia is approximately 0.25 ppm (maybe even a little
nitrite is 0 ppm, and nitrate is 0 ppm.
<dismal... see WWM re>
I admit that in being excited to start my tank up again that I
didn't condition the tank long enough. I think my LTA might have
shriveled either because of my lighting or because of the ammonia or
maybe even to just it getting accustomed to being in a new tank. Any
suggestions would be welcome. Thank You very much.

Anemone Help, no info on LTA sys., water quality...
sheesh! 1/3/09 I JUST purchased an LT Anemone. At the
time of purchase, he was in beautiful shape. Now that I have brought
him home, he has secluded into a cylinder shape and lays on his side.
He is constantly his "foot" shape... but NOTHING else. His
tentacles seem to be wrapped in a slime now. It's been 3 days...
<Bad news> I got my water professionally tested, and everything
is perfect. I'm stumped. I've heard, "pooping", but
am not sure. Thank you, Jon <For what? There's not enough data

|Anemone non-dilemma... sys./Macrodactyla
reading 7/24/08 Sherlo Hi WWM Crew <And to
you> I am writing you from South Africa and have a very new
setup. We started off with Tropical many years ago and have now
moved on to Salt Water. We have a 200gal Reef Tank setup with about
100Kg Kenya Live Rock and have recently introduced Livestock,
namely 2 x Yellow Tangs (wish I'd known about the bullying!), 3
x common Clowns, 1 x baby Blue Tang, 3 x Cleaner Shrimps, 1 x Red
Hermit and 1 x Red base LTA. [The Yellow Tangs have toned down a
bit since the introduction of the Clowns]. <Uhh...> We test
the water daily and our latest results are Ammonia - 0, Nitrates -
10, Nitrites - 0, PH - 8.2, SG - 1,023 and KH - 10. There is plenty
of oxygenation and there are no 'dead spots' relating to
the Powerheads anywhere in the tank. We are running T5's (12
hours/day) and Metal Halides (8 hours/day). All the fish look
healthy and are eating fine. My problem rests with the sole Anemone
that we have. The green tentacles are inflated and sway nicely in
the current but it keeps falling over and resting upside down or
sideways. <... this is ofttimes called the "Sand
Anemone"... please read here:
re Macrodactyla, and the linked files above...> On first
introduction, we placed it on a rock in the middle of the tank in
good sight of the halides and with plenty of current but it
"fell" down to the substrate. <...> I reluctantly
moved it back to a rock higher up to the lighting but it does not
look like it has anchored itself properly and there is some furry
substance around the red base. Also, none of my clowns are
interested in it at all! I am very concerned about it and am wary
of the addition of more anemones at this stage. <... More? A
very poor idea... again, please search, read before writing...>
Regarding the attached pic, today, the anemone is now resting with
the red base hanging over the left side of its rock ledge and the
tentacles are holding on to the rock. I look forward to your
advice! <Read. Bob Best Regards
|Identifying an Anemone 11/11/05 Hello Bob, thank
you very much for replying!! <Welcome> My question regards
trying to identify an anemone I have. I am pretty sure
it is an LTA, as these are the only ones I can find on the web that
resemble mine. I have attached some photos so maybe you
can tell me if I am correct. <Is a Macrodactyla doreensis:
One of whose common names is the LTA, yes> Also I am having a
rough time placing this little guy. (seems common with LTA
anemones, another reason I'm thinking that's what this
is...) he always seems to end up in live rock
"caves" or face down in the sand. Right now I
have him on the substrate with a clear plastic bowl over him with
holes drilled in it, which gives him just enough room to
spread out and move around a little. Anything else I should do??
<Mmm, best to "nestle" in an opening twixt two or more
rocks...> I have read that LTA like to be in the substrate, not
on the rocks. Am I correct? <Yes> Also, he has no tears to
his foot, appears very vigorous and healthy, and eagerly devours
any shrimp or squid I give him 1-2 times a week. I have had him for
about three weeks now. I have a 30 gallon tank with 25 Lbs.
of live rock, ammonia is 0, nitrites 0, nitrates very low, pH of
8.3. I also use Phosguard by Seachem to control phosphorous/algae,
and I supplement with calcium/magnesium, and add
phytoplankton. I have 3 Damsels (still there from
cycling), and a True Percula Clown, which absolutely loves the
anemone. Also I have a Peppermint Shrimp, and some Blue Legged
Hermits for algae control. My only coral so far is a
patch of purple and green Zoanthids that came in on some LR. My
substrate is 1.5 inch deep very finely crushed
coral. Any help you can give me will be greatly
appreciated!! Thank you very much Eric <About all we have
