Something in my liverock
>Hello.
>>Greetings! Marina this afternoon.
>I am new to your site and it was recommended to me by Mike
at FFExpress.
>>Excellent, our thanks to Mike, though I was under the impression
that FFExpress is now defunct/bought out by the Dr.'s (Foster &
Smith). In any event..
>My name is Tom and I have just recently (in my 4th week) set up a 65
gal salt water tank. I have Live rock, mushrooms, green stars, green
polyps, green bubble, leather coral, a cleaner shrimp, algae eating
snails, and two clowns. I plan on getting a little more live rock and in
time more coral and a couple more fish and crustaceans.
>>Right, just be sure to go very slowly, and quarantine ALL new
additions, 30 days is protocol.
>MY QUESTION is a center live rock piece I use for a shelf has some
organism that emits a little cloudy substance about every 20 minutes or
so.
>>Boring clam. No, not uninteresting, boring as in
mining. Completely harmless and nothing to worry about. Actually,
it means that your conditions make it quite happy.
>it has done this for about two weeks now and although it doesn't seem
to be hurting anything I am just curious about what it could be and if it
could hurt my tank down the road. I paid close attention to where this
little cloud came from and it appeared to come from either the red growth
in the rock or something underneath it. It must be something small as I
tried to use the turkey baster to suck it out or remove it and nothing
would budge. The cloud is a quick short burst as if being blown out. It
appears almost like a little slimy and milky emission that disperses in
the water then dissolves away. I cant explain it any better than that.
>>You've explained it very well. You have one of the
goodies people hope for with good quality live rock, and hope not to lose
during the curing process.
>Like I said it has done this for a couple weeks now and I have tested
my water taken my water in to be tested and so far so good. What do you
think about this or do you know what it could possibly be. Thanks for your
time. Sincerely Thomas East
>>Right, I really think it's a boring clam, and certainly nothing to
worry about. Have fun with him, they're odd little beasts! Best
of luck with your new endeavor, it appears that your setup is looking very
good (a bit unusual for many newcomers AND such new setups). Marina |

Culturing the Thorny Oyster? How about Keeping it Alive? 7/18/04
Hi, great site. I read everything you had about the thorny oyster, and have
been searching the internet with only limited success.
<there is not much info known/published on them for aquarium use... they are
extremely difficult to keep alive and most responsible aquarists leave them in
the ocean, or at least don't buy them>
I have become a great fan of the thorny oyster and have decided I would like to
have a crack at spawning and/or culturing the animal.
<keeping them alive for even a year would be a great feat in itself. Most hang
in for some months (a few over 6 months) before finally succumbing to
attrition/starvation>
I was hoping to find a source of spat or small oyster seed and/or instructions
on how to induce spawning.
<do look into the fisheries data (use university libraries/databases for this)
on Tridacnid clams and other better studies bivalves. There is much info there
to be assimilated I'm sure. Gerry Heslinga is a pioneer here and did some great
papers on the sub-family Tridacnidae. Temperature, salinity shock were used at
times... also serotonin infections as well as other hormonal treatments. Some
bivalves will simply spawn just by the sensation of an egg in the water
(sacrificing a ripe specimen for eggs top disburse). This all presumes that you
can even rear your oysters to be sexually ripe/ready, and frankly... no-one can
clearly say what it is that they eat in captivity or how to provide it. Bottled
phytoplankton is unlikely to be a solely adequate staple>
I have three oysters from local fish stores. I have read everything I can find
on Husbandry of the Giant Clam, and a bit on Cultivating popular eating
oysters. Can you direct me to a source of oyster spat/seed for the Thorny
Oyster, and/or groups doing oyster raising locally in the US. Thanks, Kevin
Meade
<I share your admiration for this animals... but as my third query of the hour
from a person that bought an animal that they do not know how to keep (what they
even eat or if they can provide it), you have honestly bummed me out mate. No
hard feelings. but please do consider the seriousness of the matter. If you are
the one man that knows how to feed and keep Thorny Oysters in captivity for a
full lifespan and not just a few weeks/months from purchase, then you need to do
the industry and science a favor by telling us how (with all due respect here,
sincerely). If not, I assure you that yours will be dead inside of 12 months. I
have no wisdom to share other than above here. Anthony>
