Anemone Ate Hermit Crab - 7/18/07
Hi!,
<Hi Sol!>
Today I
bought some tiny hermit crabs, no more than 1cm across. When I put them
in they started to walk around the tank. Before long one of them had
found <it's way(?)> in into the tentacles of my anemone (Heteractis
magnifica). It has now completely consumed the hermit crab into its
mouth (about 4cm across). Is the anemone going to be ok? <Should be
fine. The anemone will regurgitate the shell/what it can’t consume.)>
I'm not so worried about the hermit crab, but I don't want it to start
eating from the inside out. Can you please offer your
advice. <See
above.> Thanks a lot in advance.
<You're very welcome! -Lynn>
Regards,
Sol Jennings
H. magnifica, Lighting, Feeding – 7/3/07
Ok, here is the story:
In the past I have lost 2, H. magnifica's that arrived in perfect
condition. I kept them in my tank under T5 with independent parabolic
reflectors. Many people will blame it on the light. However my light is
keeping the most demanding SPS under perfect conditions.
<I would
have to agree this is not adequate lighting for this species. This
anemone needs higher lighting than the most demanding SPS. I also don’t
recommend keeping corals with this anemone.>
My LFS who build my tank
and is a total expert, said that he kept an H. magnifica for 3 years
under T8s! The anemone finally died because some idiot put in a fish
that had been washed with a copper solution.
<I’m not convinced this
was the only factor involved in the anemone’s death.>
He said then
the secret was not so much on the light but on the water quality and the
diet.
<Lighting, water quality, flow and diet are all huge factors in
the survival of this anemone.>
The diet consisted on mixing good
brand of flake foods with water until it became liquid, then he would
grab a syringe without needle of course, and pour the liquid food into
the anemones mouth.
<Ouch! Force feeding an anemone is not
recommended. This can be very stressful on an anemone. Flake food is not
an adequate diet for any anemone. They need small portions of meaty
foods.>
This seemed interesting because my H. Magnifica's never ate
the pieces of shrimp I gave them, I placed them inside its mouth and it
just threw it out.
<Again, never place food in an anemones mouth.
Their tissue is very delicate, if torn, your anemone may quickly parish.
If your anemone won’t willingly take the shrimp, try something
different. Small portions of Silversides, Mysis Shrimp, Lance fish, etc.
That syringe should only be used to get the food to the tentacles of the
anemone, without actually touching the anemone. An anemone will
regurgitate what it is unable to digest. Force feeding or too large of
portions was likely the cause of it regurgitating. Start out with tiny
portions and never feed anything bigger than the anemones mouth.>
So
has anyone tried to feed liquid foods into a delicate anemone's mouth?.
Do they accept it this way?
<I’m not aware of anyone force feeding
liquid foods.>
I blame their deaths on the fact they were rather
large and never ate.
<Anemones are considered difficult to keep. This
anemone is considered most difficult to keep. Collection and shipping
alone can be deadly for this species. It is probable that they wouldn’t
eat because of the stress caused from the collection and shipping. Many,
including myself, believe this anemone should be left in the ocean. This
anemone is dieing at a faster rate in captivity than it is reproducing
in the wild. I hope this helps! Brenda>
Feeding new Ritteri
anemone
I apologize for sending this as you have so much
information already on your site, but I'm finding some conflicting
information from other sources.
<no worries>
I recently ordered a
Ritteri anemone from Flying Fish.
<a beautiful anemone, but rarely
to be recommended (poor import and captive survivability... never to be
mixed with coral or other anemones either). This anemone, after proper
acclimation over days/weeks... needs brighter light than even the most
demanding coral. Metal halides for aquaria over 20-24" for this species>
It arrived and is beautiful and appears healthy. It quickly climbed to
the top of the tank, where it has stayed for several days.
<very
typical Ritteri behavior... they starve for bright enough light>
It
is a large specimen 8-9 inches across.
My question is what to feed
this beast. Your site references finely shredded marine meats in
several places, but I find other sites that say pieces of shrimp or
squid the size of the anemone's mouth.
<no harm in feeding the
minced pieces... possibly (likely in time) damage from tears with too
large chunks>
Could you clarify what types of food would best support
this new addition to my system?
<Mysis shrimp, Pacifica plankton,
shredded raw food shrimp, minced krill>
Thanks much as always, Scott
<lighting is most important here bud. Very bright and maintain water
clarity (weekly carbon, water changes, etc). Anthony>
Re:
Feeding new Ritteri anemone 2/5/03
You mention that this species
should never be mixed in a tank with other corals.
<correct for all
anemones essentially. As an added fact (ironically an exception with the
ritteri) very few anemones are found anywhere near corals naturally on a
reef. A gross generalization... but true for most>
Unfortunately,
this is a 120 reef with several varieties of coral.
<it is commonly
where they go in captivity, alas>
That's what not enough research
before making a purchase gets me. Why should this species be kept away
from corals?
<they are motile stinging animals (the anemones) being
kept among sessile ones (the corals)... its a recipe for disaster in
time. You've already watched yours promptly crawl up the reef to the
top... they move at will and sometimes frequently. Its Murphy's Law
too... it will stay in place until you go on vacation... then get into a
fight with a coral... one or both will die... and the rotting body can
corrupt water quality and kill the entire tank for it. Other than that
<G>... Heehee. My very string advice for this and all anemones is to
keep it alone and as a delightful focal point in a species tank. How
about a 60 hex by a window for sunlight and keep a dozen small
aquacultured clowns swarming about it? If left with the corals... there
are still huge issues with cnidarian allelopathy between such unnatural
tank mates in the confines of an aquarium. Wherever you choose to keep
this anemone, please be sure to protect this motile creature from pump
intakes and overflows/drains/strainers. Too many die this way. Best
regards. Anthony>
Heteractis magnifica anemone
Good
morning!
<Howdy>
I have a 65G with 4x36" VHO lamps (4x95watt).
75lb of LR and a few corals, but growing. The water quality is very good
(no ammonia,
nitrites, nitrates) and I add the SeaChem supplements
(Reef Plus, Reef Complete, Reef Calcium, Reef Advantage Calcium, Reef
Builder). I have a
"happy" pair of Amphiprion ocellaris clowns and I
would like to add an anemone.
<I almost hope that you do not.
Anemones generally do not fare well in captivity for hosting clowns and
the are sure to fail if you also keep other corals or anemones in the
tank. They generally require more lighting to survive than a full blown
reef tank and most people are not willing to spend that kind of money.
If you are truly endeared to the thought of keeping these cnidarians...
then please set up a species tank with only the anemone and these clowns
IMO>
The only reason I want the anemone is so I can watch my clowns.
<again... most anemones in captivity suffer for so many reasons... not
the least of which is the unnatural feeding of large foods by you and
the clowns to the host, the lack of light (halides needed here) and the
repetitive contact. Field studies show that there are fare more anemones
living in the wild without guests than with>
My understanding is that
this type of clown does not always "take" to an anemone.
<correct...
have you read through our archives here? Many pages of articles and
FAQs. Begin here:
http://www.wetwebmedia.com/marine/inverts/cnidaria/anthozoa/anemones.htm
and notice all of the links for this group down the page here:
http://www.wetwebmedia.com/marine/inverts/index.htm >
My first
choice for an anemone would be a Heteractis magnifica, but specifically
either a blue or purple one. I've read that there are 3
anemones that
ocellaris clowns prefer: Stichodactyla gigantea, Stichodactyla mertensii
and Heteractis magnifica. Here's my question: Is
the Heteractis
magnifica a good choice for my clowns,
<it is compatible... but one
of the most difficult anemones to acquire healthy and keep healthy in my
opinion. A brown carpet anemone would be a much better choice>
will
the color affect the chances of them "taking" to the anemone,
<nope>
and how do I encourage them to "take" to an anemone?
<in will come
naturally or not. No tricks needed>
Thank you in advance for your
help.
<with pleasure and hope that you succeed>
I saw on your site
that you recommend reading Dr. Ron Shimek's pamphlet called "Host
Anemone Secrets".
<just one of many references to consider>
Where
can I find it?
<numerous places on the web. Some of our sponsors on
wetwebmedia.com carry it... but have you also simply tried a keyword
search on a general search engine for [buy "Host Anemone Secrets"]? Be
resourceful bud. Amazon.com also sells it I'm sure.>

Ritteri Anemone Not eating
Hello
Again,
I purchased a Ritteri Anemone 2 weeks ago, I have been trying
to feed it silversides, Krill Mysis, and other food. It will not eat for
some reason.
<Mmm, something important to impart to you re: other
animal groups and subjectivity of reality... You are very likely
familiar mainly with other warm-blooded animals... e.g. birds, dogs,
cats... Anemones are different in a fundamental aspect... in their rate
of reactions, acclimation to new settings... Your addition is just
starting to settle in... I might've used the comparison between your
referent to time going by, with that of a Galapagos tortoise and a
hummingbird...>
There are a pair of clowns that made it their home.
<Oh, and these are likely feeding it... foods, scraps, their solid and
liquid wastes... many anemones actually need very little offered "food">
It's in a 29 gal tank, 0 ammonia, 0 nitrite, 30 nitrate...
<This is a
very dangerously small volume of water... the changes that take place in
little bits of water/aquariums, the changes that anemones and other
cnidarians effect in their immediate environments (greatly diluted by
larger systems, the seas) can create a deadly, unstable, toxic
situation... in short order. I would NOT keep this animal in less than a
hundred gallons of water.>
Water changed every week. I add all trace
elements, 130watts PC lights. I spoke to the LFS they stated they do not
know why it will not eat. Another strange thing is, I had one before and
it moved all the way to the top of the tank, But then I only had about
80 watts lighting. The mouth is tight and good color, the toe has no
signs of rips, tears or any damages. It looks healthy and tentacles are
all out. Do you have any Ideas? Thanks. Kim
<Lots... sorry for Anthony to see the Steelers go down in flames... but
re your anemone, you have a bit of studying and soul-searching to do...
its husbandry is too difficult in the present circumstances... You would
do well to read over our archived materials, starting here:
http://www.wetwebmedia.com/marine/inverts/index.htm scroll down to
"Anemones, Actinaria"... and read my friend. Bob Fenner>
Ritteri Anemone
Hello Mr. Fenner, <James here for Bob>
I
addressed this to you because my wife wrote you a while back ago about a
Ritteri we purchased. It is still alive and of course did okay for
awhile. The anemone is in a 29 gal with 2 Maroon clowns at this time. I
am putting finishing touches on my 300 gal.
(Let it cycle). I
change water every week. Parameters are fine. There is 130 watt P.C. on
it right now. It has attached to the side of the tank (Which I know this
is normal) but it never did climb to the top like they do. It stayed in
the main flow of the pump which is about 400gph. When purchased, it Had
a good looking toe. No rips or tears or signs of healing from tears.
When purchased It was on a flat rock. I wouldn't take it with out it.
The mouth was tight and closed, no gaping. The mouth is still in great
shape. I tried feeding it , it eats once in awhile for me, but the
clowns spit Mysis, and Spirulina flakes in the middle. It closes up and
digests and then opens up. Now here is the problem, The toe started to
turn whitish, on the part that sticks to the glass. Then it got concave
like ( In the middle it is detached from the glass, but the ends are
still attached to glass). The past dew days it has not fully opened and
falls almost all the way off the glass. (Here is the funny part- not so
funny) At night 30 minutes after the main lights are out, moon lights
on, it re- attaches to the glass all the way. It stays there until the
main lights go back on during the day time. It is almost like the light
is too much for it, I did not think that was possible. Ammonia 0,
Nitrite 0, Nitrate 20. I do add Iodine,<you need to test for levels of
iodine. Too much can be harmful. It is hard to know how much of this
the animals absorb.> Vitamins (To water) and Iodide. I have a sump rated
for 180 gal. and a protein skimmer. I do notice the Maroon clowns,
especially the female, really is very rough with it, but boy you stick
your hand in there for cleaning and forget it. She broke my plastic
spoon, and before she laid eggs last month she re-arranged the tank
moving rocks 3x her size. I called my local fish store and they have no
clue. They told me when it dies they could get me another one. That's a
real great response!, how does that help this one. Anyway do you have
any suggestions, I have never seen a anemone act like this. <I do think
your lighting is borderline for this anemone. They do require strong
lighting and water motion. They generally do poorly in the home
aquarium but with care and proper conditions some have lived for
years. What I would start doing is a 10% water change with an enriched
salt mix such as Reef Crystals, make sure that iodine level is safe and
keep the light on for 12 hours per day. Cut out direct feedings for a
while since it sounds like the clowns are giving it enough. The anemone
does provide a great deal of it's own food by photosynthesis providing
the lighting is intense enough. What type of filtering are you
using? James (Salty Dog)>
Thanks, Scott
Ritteri Question
Hi!
<Hello! :D>
Could you explain why my 3 percula clown fish keep
knocking and taking the pieces of cockle I place in my anemone out of
it?
<Simple - they want the food!>
I had a magnifica anemone which
I only had for a month before it suddenly died and have just bought
another similar anemone 2 days ago which looks great.
<Problem with
these guys is they require extraordinary amounts of light (I know of
several specimens that have parked themselves directly under 400w
halides) and require tons of flow (in the thousands of gallons per
hour). They're very difficult to keep in captivity and I usually never
recommend attempting one without years of anemone keeping experience>
The clowns took to it within minutes of it attaching to a rock in the
tank but keep knocking any cockle it has in its tentacles out. Should I
leave the feeding of it solely to them and it's reliance upon whatever
it gets floating in the tank or
persevere with trying to hand feed
the cockles?
<Definitely not - keep the fish away from the anemone
while it eats, and feed it well while it's acclimating>
I also have a
problem with feeding my white blue-tipped Malu any cockle etc, before it
gets chance it's whipped away by my coral beauty angel fish-any
suggestions?
<Scare the fish away with a net or your hand while they
are ingesting their food. Please read our archives regarding Ritteri
(magnifica) anemones, and see the sticky posted under the anemone &
clownfish forum at reefcentral for more info>
Many thanks in advance
<You're welcome, good luck!>

Moorish Idol
Survivability (Poor), feeding a big Ritteri anemone - 10/12/05
Hello All,
<<Greetings>>
I want to try to get two topics for the
price of one.
<Alrighty>>
All is well nothing sick, just general
questions of curiosity.
<<ok>>
The first is my Moorish Idol.
<<Mmm...>>
I have had him for about 6 months. When I bought him he
was a little under weight and had a cut on him. He is doing awesome.
<<For now maybe.>>
His color is vibrant, cut has been gone for
months. He is about 6-8" so he is good size.
<<agreed>>
He is
eating, Seaweed Selects, frozen Mysis, live worms, alga wafers, you name
it he eats it.
<<Sadly, this usually still proves to be insufficient
with these fishes.>>
He is the first one in line when I feed, also
eats flakes. When I first got him all he would eat is wafers. My
question is, I was reading a article that stated no matter how good they
do, they will perish. Something about a enzyme they eat in the wild,
that we can not produce in an aquarium. Is this true?
<<Not familiar
with the "enzyme" theory, though it does go with what I've heard/read as
far as not being able to accurately reproduce the dietary requirements
for long-term health/vigor. I've been in this hobby a long time and
tried; albeit unsuccessfully, to keep Zanclidae more than once (has been
more than 10 years since my last attempt). They all would eat, seem to
be healthy...but then one day, two or ten months down the road, you come
home or get up to find it dead in the tank for no "apparent" reason. All
you have to do is look around you...how many Moorish Idols do you see on
display, or in other hobbyists tanks (long-term)? It's not because they
don't have appeal/are not available to the trade. I wish you luck, but
this is another specie best left in the sea.>>
Secondly, about 2
months ago I purchased a Heteractis magnifica. It has a extremely deep,
colorful purple base. Never have seen one like this. It is about 24"
wide. It is huge!
<<And will likely get bigger.>>
I have read
conflicting articles on FAQ's and others. Some say to not feed it at
all, let the clowns do it (They do but not much).
<<Mmm, nope...needs
to be fed.>>
Some say to feed it chopped silversides 1-2 times per
week.
<<Not the best diet...do provide some variety...chopped table
shrimp/fish.>>
Others say once a day.
<<Maybe more like 2-3 times
a week.>>
Due to the anemone being so large, I have been feeding it
chopped silversides and shrimp daily. It seems to be doing well.
<<This might be fine (small portions). Let the anemone's health/appetite
be your guide.>>
I just am trying to be pro active and not reactive.
<<Does pay dividends.>>
Thank you for your valuable time.
<<Happy
to assist, EricR>>
