Creature ID/FAQ Direction...
Oculinid Resurrection! -11/25/07
Top of the morning WWM Crew,
I have browsed the site looking for some assistance with an ID. I originally
purchased 2 pieces of Live Rock that were barren at the time, and since they
have literally sprouted with some interesting anemone looking creatures. The
first two attached are of the darker rock, upon which 15-20 tiny purple based
with greenish tip organisms have appeared. They do not appear to have mouths
like an anemone would, but they seem to be of the same consistency based on how
they move with the water flow in the tank. The second set of pictures of are the
lighter rock. I was unable to snap a picture of the backside of this rock, but
many completely clear more pointed organisms are starting to emerge out of these
'chambers'. Any assistance would be appreciated, I would like to read more about
these organisms, get up to speed on whats in the tank!
<Haha, that's not just live rock my friend, that's coral! Apparently, whoever
sold it to you thought the coral was dead and so sold it to you as "rock." But
the coral (a Galaxea sp. from the looks of it) is now coming back (and
spectacularly so). Congratulations! :)>
Happy Holidays, -j
<Gracias, y tu tambien,
Sara M.>
Re: Creature ID/FAQ
Direction -11/25/07
Ahhh Excellent! Thanks so much for your assistance I will read up ASAP.
I did not think my 2-t8 32 watt bulbs would be sufficient to foster
coral growth (55 gal tank)
<Well, actually, Galaxea sp. don't need much light.>
But they seem to be multiplying rapidly!
<It's pleasantly surprising to me too. Especially since, if it was sold
as live rock, there must not have been much more than a few bits of live
tissue left. We know that, theoretically, corals can come back from even
just a tiny "drop" of live tissue. But it's exciting to see it actually
happen (especially when you're not even trying or don't even know it's
there! lol). May I ask, what do you feed the tank? It might be helpful
for people attempting to revive such dying corals to know more about
your system. And please don't be shy... if your nitrates are through the
roof or something, please share anyway. It's always interesting, when
someone has this kind of great, unexpected success, to know all about
the conditions under which it happened. :)>
Diligent research incoming, thanks again! -j
<Very good, but before you think about changing anything, please keep in
mind that whatever you've been doing, it's been working for this coral.
Best,
Sara M.>
Re: Creature ID/FAQ
Direction 11/26/07
Haha! Yes, I found both pieces in a live rock bin at a LFS, walked out
with both for under $20. The darker rock has propagated quite a bit in
the short amount of time it has been in the tank (1 week). The lighter
rock is beginning to sprout the clear organisms I spoke about. Is the
lighter rock a Galaxea Coral as well?
<Well, it was at one time. It's hard to say if there's anything living
left on it. I'm sorry I was unable to see the "clear organisms" you were
referring too. It *could* be bleached out coral tissue. But I honestly
don't know without a better picture (and preferably with the unknown
thing circled).>
Nothing to be ashamed about, I'll post the stats. I also attached a
picture of the tank. I don't see anything out of the ordinary with my
setup, is it normally difficult to "revive" these type of corals?
<In my experience, it can be a difficult thing to do when you're
deliberately trying to do it. But, as you can see (and as has happened
to me too), sometimes they just come back without much aquarist effort
at all. Corals are just weird that way sometimes (or they seem so
because of how little we really understand about them).>
55 gal
2 t8 32 watt bulbs (actinic and full spectrum)
Fluval canister filter with activated carbon.
3 Maxi-Jet 1200 Powerheads
Inhabitants - O. Niger Trigger, Maroon Clown, Longnose Butterfly.
Assorted Hermits and Snails. Cleaner Shrimp.
Tank parameters
Gravity - 1.023
PH - 8.3
Ammonia - 0
Nitrite - 0
Nitrate - 0
Temp - 78
<Your salinity and temp are a little low (1.025 and 80-82F would be
better). But like I said, whatever you're doing is working so I wouldn't
change anything too quickly.>
I feed defrosted Mysis shrimp once daily soaked in Selcon.
<Hmmm... maybe the Selcon is helping? The strong water flow certainly
doesn't hurt.>
I was not planning on changing anything (if its not broke....) but I was
curious if I needed to supplement feedings/care requirements of the
coral. Will research the FAQs. -j
<Here are some links to help you out:
http://www.wetwebmedia.com/oculinidae.htm
http://www.wetwebmedia.com/galaxycfaqs.htm
http://wetwebfotos.com/Home?actionRequest=articleView&articleID=299
http://www.asira.org/galaxea
They're actually not considered "easy" corals to keep. They feed on
small particle food and, when healthy, can be extremely aggressive.
If/as this coral continues to grow/thrive, it will probably need to be
feed more and maybe given some space. But as they say in AA... best to
take it "one day at a time." :-)
Good luck and thank you for sharing about your coral/system,

Live rock, White Squiggles...
Possibly Spiral Tube Feather Dusters (Spirorbis spp.) 11/17/2007
Hey there,
<Hi there, Mich here.>
I noticed some white "worms" imbedded in my live rock when setting up salt water
tank and now, 5 months later, they have what looks like very faint, very tiny,
light pink "flowers" coming out of each "worm". These white "worms" are
hair-like and 1/4 inch long. The worms don't seem to move and are still imbedded
on the rock. The "flowers" seem to retract when a fish touches them. They are
mostly on one or two rocks. What are these? Are they baby feather duster worms?
<Likely so. Sounds like spiral tube feather dusters (Spirorbis spp.)
You can see one not terribly clear image here:
http://www.wetwebmedia.com/snailid12.htm >
And a better pic here:
http://calphotos.berkeley.edu/cgi/img_query?query_src=photos_fauna_sci-Invertebrate&enlarge=0000+0000+0805+0709

I have a polyp growing on the same rock, I hope they are friendly to each other.
<Should be if this ID is correct.>
I am looking forward to watching these grow!!!
<Yay!>
Thanks! Tara

Help With
Identification of Something Growing on Rock... A Sponge 11/9/07
Hi,
<Hi Carlos, Mich here.>
Thanks for the great web site...
<On behalf of Bob and the crew, you're welcome!>
it has been a great source over the last year with my reef thank.
<Glad to hear!>
My tank is doing quite well and appears healthy, but I have had this
rock with mushrooms on it for about 9 months. I have noticed over the
last few months a yellowish green substance filling some of the
crevices. It is semi-transparent almost gel like in appearance. I tried
to scrape it off a couple of weeks ago while cleaning the tank but it is
actually quite hard to the touch. I have enclosed a photo and outlined
it in blue. As you can see there is a tubeworm that is being covered by
this substance. Any ideas on what it might be?
<Yes, is a sponge. Impossible to identify much beyond this without
microscopic analysis.>
My tank is about a year old.
36-gallon corner tank.
65 pounds of live rock
30 pounds of live sand refugium with Chaeto and two small rocks with
zillions of Mysis shrimp and pods. <Yay!>
2 Montipora
1 Acropora
1 small hammer coral
1 frogspawn
pearl bubble coral
xenia sp
open brain
plate coral
3 Ricordea mushrooms
tube worm...going on a year
2 small percula clowns
1 Royal Gramma
1 Randall goby with pistol shrimp
<Lots of potential for allelopathy in such a small system! Hope you're
doing frequent water changes!>
pH 8.1-8.2, temp 79-80, ammonia, nitrite at 0, nitrate fluctuates
0-15, Calcium at 390-420, Alk at 4.0, sp grav approx 1.027 <A bit high>
Thanks for your help.
<Welcome! Mich>

White powder
on live rock 10/2/07
Hi,
<Hello there>
I have a 55 gallon tank with sump and remora skimmer, 50 lbs LR, newer
tank with only 6 snails, two percula clowns, and a banner cardinal.
Water parameters are Amm-0, Nitrite-0, Nitrate-2ppm, phosphate-0,
calcium-460, dKH-7, sp. gravity 1.024, ph 7.8. I have been using oceanic
salt with I think explains the high calcium and low dKH.
<Not unlikely>
I perform 20% H20 changes per week. I recently had a diatom bloom, which
began to subside.
<Will in time>
I noticed that green micro algae and even small amounts of pink
coralline algae started to grow on rocks previously covered in brown
diatom. However, today I noticed white powdery substances covering
portions of live rock where algae growth was previously noted. Could
this be die-off occurring on the live rock.
<Yes... and growth of other organisms... that are whitish>
The live rock was fully cycled when initially placed in the tank.
<Mmmm, okay>
The tank instantly cycled without ever having any measureable ammonia or
nitrite, so I didn't think this would happen. The white material easily
blows off
the rock when a powerhead is aimed at it. Any ideas what this could be?
Photos are attached.
Thank You,
Sean
<Is largely a mix of biological and physical "settling" of materials
from processes to be expected in a new system... I would increase
circulation, "blast" the bulk of it off with your pumping device/s...
and not sweat its presence for now... It too will pass. Bob Fenner> |

Live rock... life IDs
8/18/07
I am just interested what might burrow into live rock. Recently I have found
several holes in my live rock that all have a pile of sugar fine rock particles
below the hole. Thanks.
<Mmm, all sorts/phyla of organisms... likely crustaceans, worms or bivalves of
some sort here. Bob Fenner>
LR hitchhiker ID...
Pseudocorynactis sp. – 07/23/07
Hi!
<Hello again to the (fermented?) Jedi Master! Mich here.>
Can't seem to find an id for this guy. It looks like an anemone, with a
white center, pink around the center, translucent tentacles, and white
tips. Please help!
<The force is with you small green wise one! You have a Pseudocorynactis
sp., likely an orange ball Corallimorph (Pseudocorynactis caribbeorum).
They are generally nocturnal (like me) and not much is known about their
care requirements. But they are quite pretty and I have been fortunate
enough to have several survive in my tanks for a number of years. I wish
you the same!>
Thank you very much!
<You are quite welcome! Mich> |
