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.

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.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, Sara M.>

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
<Welcome! Mich>
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.

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.

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> |
