Anemone? 07/20/2008
Dear WWM:
<Kevin>
My tank is a 72
gallon saltwater FOWLR but has a couple isolated corals.
Single
protein skimmer and several powerheads. Only four fish at present (a
waste, for sure). (Also seems to have a fair amount of Cyano but
that is a story for another day!) I have had extremely little change
to the tank over the last three years, except for the introduction
and subsequent death of a few small fish.
<Mmmm>
This very
slow-growing presumed anemone is about 2 inches across. I haven't
been able to find a photo of a similar specimen and I don't trust my
LFS for this kind of info. It looks like none of the aiptasia I
eradicated a few years ago, but I just wanted to be sure it is OK
for my tank. Thank you for
your help!
Kevin
<Looks more
like a Zoanthid or Corallimorph to me:

Thanks a lot. I never would have figured it out.
I'll
research it to find out how to care for it.

Ghost shrimp/jewel anemone hlth/ID - 07/19/08
I can't seem
to find an answer for my questions.#1 I bought some ghost shrimp
from my LFS and I noticed they had some white dots on their body, is
this normal or some sort of disease?
<Mmm, likely more the
latter... not communicable though. These sorts of markings show up
in specimens that have been kept in poor conditions>
#2 I have a
large colony of jewel anemones
<There are a few species that go
by this name... Is this a Corynactis? Which do you have?
and
can't find any info on them any where can you tell me or give me a
link to some information on them? Thanks for any help!
<Bob
Fenner> Re: Ghost
shrimp/jewel anemone 07/20/2008
Wow I didn't think I would
even get a reply yet alone a reply so quick!
So then it would be
safe for my fuzzy dwarf lion to eat said ghost shrimp his health is
of great importance to me. #2 yes my jewel anemones do resemble
Corynactis and now I have their scientific name I'm finding a lot on
them. I saw tanks full of them at Chicago's Shedd aquarium that's
were I got the jewel name from. thank you very much. I'm sure your
words of wisdom have prolonged the lives of many of our aquatic
friends!!!
<<Yes, the ghost shrimp are fine for the lionfish.
Really glad you found the correct name for your anemone, all helps
towards providing a better environment for them. Thanks for the
follow-up, hope this helps. A Nixon>> |
It looks and swims like a jellyfish, could that be? 6/19/08
Hi Crew,
First I want to apologize for the quality of the
picture. This thing is Tiny! Maybe I could send a better one in a
few weeks when I get my new camera. I have 2 of these things
swimming around in my molly tank. They seem happy, the mollies leave
them alone. I should mention my mollies are kept in a full marine
environment, with a salinity of 1.024-1.025. They're (the mollies)
are kept in their own tank and not with my other marine fish and
corals . The tank has been set up for over a year, with just a
smidge of live rock that I've moved over from my marine tank. My
daughter starts yelling about jellyfish in the tank about a week
ago. Though I've seen these things many times a day, they swim like
jellyfish, (flapping their dome tops up and down), they look like
jellyfish,( domed top and a couple tentacles). That doesn't mean
it's a jellyfish. Do you have a clue?
<The picture is far to
blurry to say much of anything sure. There are "pest" anemones that
can "swim" like jellyfish. This would be my guess. I'm sorry I don't
know the proper Latin name/classification for them. But I've seen
them many times, and they do look a lot like jellyfish when they
"swim.">
I've tried to research them but I don't know what I'm
looking for. Some sort of egg that hitched in on some rock I
suppose. I'm not worried about if it was indeed a jelly, maybe they
would keep the fish population under control in there. I do supply
that tank with phytoplankton and keep the parameters in check as I
do with my main saltwater tank (except for nitrates, the mollies
don't care so I use tap water in that tank only for water changes).
<I wouldn't worry too much about them unless they reach plague
populations. I also would avoid touching them. Depending on a
person's sensitivity, they might sting or cause a rash... as all
hydroids/jellies and/or anemones/stinging celled animals have the
potential.>
Thanks for your help,
Rochelle Lee

Please identify this 6/1/08
HI, I was hoping you could
identify something for me. It totally defies anything that I've read
about and I'm stumped. Attached are two pictures one of the 'thing'
open and one of it closed. It came attached on a piece of rock about
6 months ago. It only opens when the lights are out and has clear
tentacles with balls on the ends that are sometimes white, when the
lights come on it closes up and the outer "casing" is red, it also
closes up like this when agitated (usually by shrimp feet) or when
its gotten hold of food. It has stayed the same size since I got it,
probably from lack of food (since I feed when the lights are on and
its closed then). thanks! Sadie
<Is a stony coral
(Scleractinian) of some sort... perhaps a single polyp species
Caryophylliid... Bob Fenner> |  |
Please ID this
Hi, all. I have searched endlessly on your site
and can find nothing resembling what I have on a piece of rock in my
soft coral tank. First off, This came on a piece of rock that had some
mushrooms on it about mid March. These two creatures you see were hardly
noticeable when i brought the Shrooms home. I did see it, however and
cut the rock to have this as a separate specimen.
<Good move>
The
larger of the two was about the size of a small Zoa when I noticed it.
The other was hardly able to be seen. There are a total of 5 of these on
the rock and they seem to be localized on this small piece. They do not
have a mat and are not connected.
<A good clue>
The largest one
that you see is about the size of a penny, now and the other is catching
up. They remain open like you see them almost all the time and will
catch mysis to eat. I have
seen no sweeper tentacles and they have
not physically moved themselves. I feel like I can rule out anemones.
There is no hard skeleton that I can see, either.
<Mmm, I do>
Can
you help?
<Likely these recruits are Fungiids:

perhaps Cycloseris sp.>
Thank
you

Coral ID 03/30/2008
Hi everybody,
This is Sam from India...
<<Hello Sam, Andrew today>>
Hope all are doing great out there!
Well, I recently got this soft coral shipped, which was in the box for
two nights, but has made it quite well, was a bit wounded, but seems
fine now.
I know that it is a leather coral, but I wanted to get a
proper identification from the experts.
Can you ID this coral's
genus, species would be even better!
As, then I will have better
understanding of its needs.
Please see the attached picture, the
coral had come three days ago, when it came in it was totally shirked
and dark in color, now it is a
little larger and turgid.
Basically, I don't know how it looks when the polyps are fully extended.
So, knowing the species will help compare images for indication on
health!
Also, looking at the image what do you feel about its health
and condition, how large does it extend it polyps?
Also, how much
time does and average soft coral take to molt?
<<Ahh yes, a leather
finger coral by the name of Lobophyton. Looks in a nice condition, and
will look even better when it extends out>>
Thanks in advanced!
Cheers, Sam
<<Thanks for the question. A Nixon>> |

Hairy Mushroom [not] 03/25/08
Hello,
I purchased a large
mushroom shown in the attached pictures some time ago, it is in my Red
Sea Max. I assume it is a hairy mushroom but not exactly sure?
<Oooo,
no, not a Corallimorph. It is a leather coral, looks like a Sarcophyton
sp.>
As you can see it is budding (if this is the correct term) a new
mushroom from its base which seems to be doing really well. As I
understand it, it will move further out from the shade and grow full
size. What I am not sure of is if it will detach itself
<likely>
and how long will it take?
<It just depends on how fast it grows.>
I was also thinking of propagating this 'fledgling' and I am not sure
how long to leave it before I do this?
<Leather corals are very easy
to frag. You can do this at any time you like if you don't want to wait
for it to detach on its own. Please see here:
http://www.wetwebmedia.com/softcorpropfaqs.htm>
You can also see that
my Maroon Clown has 'moved in', it seems to act as if it were an
anemone, is this normal?
<This is quite common.>
I do have a sand
anemone (but it usually only opens up at night) which the clown ignores.
Any ideas?
<Not really. It's difficult to "force" these things. The
only "trick" I've heard of that might work for helping anemones and
clown fish "bond" is to put the two in a small bucket together for a
little while (but not long enough for the water to spoil). I don't know
if this works, but Rod Buehler says it can sometimes. You might also
read through some of the info here on WWM,
http://www.wetwebmedia.com/clwnfshanefaqs.htm
http://www.wetwebmedia.com/clnanemfaq2.htm
...and other pages.>
Thanking you in advance for any help you can give.
