Fragmentations 7/31/05
Dear Bob,
<Keith>
I just recently found your web site, and have been reading through many... many
of the FAQ's. I have a few questions of my own I hope you will be able to
answer. Before that, I will describe my current system (running for 5 years now
but I have had a reef tank for 12 years now). I have the following system:
a.. 240 gallon (all Glass Tank) - predrilled in rear corners for water flow
to/from wet dry
<Ooof! Please don't call me if and when it's moving time!>
b.. 2 400W 20k metal halides
c.. 4 6' VHO's (IceCap 660)
d.. Venturi Skimmer (can't remember the mfg. but it is about 2 feet tall)
e.. 60 gallon wet-dry (I currently only have live rock in sump with some
carbon bags - no other bio media)
f.. Aquatic Lifestyle Systems CR-250 calcium reactor
g.. IWAKI power head (22.4 gallons/min)
h.. 1 sea swirl (center of tank)
I.. 24gal/day RO unit (this fills a 100 gallon mixing tank in the basement and
also tops off my wet-dry sump (I have it dialed in using needle valves)
j.. 200 LBS of live rock
k.. 38 types of corals (mainly LPS and SPS)
Other nice features include plumbing from my sump directly to a drain tub in the
basement and my 100 gallon mixing tank. this makes water changes a snap and
ensures I never have a overflow problem in my living room.
Over the past 5 years I have slowing added functionality to my tank to make it
more maintenance free (or at least to a level that makes me happy). I am at a
point now where I am taking large coral fragments every month to the local reef
shop for credit. I have been thinking about creating 2 or 3 400gallons
propagation tanks in the basement to harvest and sell corals. I did read your
articles on this subject and was wondering what you though about a web based
business of coral fragmentation.
<I have a few friends that have/operate these... have built out such facilities>
I have not put a business plan together yet but plan to very soon.
<Ah, good>
On another subject, I have read about the refugiums and was wondering what
benefits it would provide over my current system. I have seen these systems at
the local store on the display tanks and do not see a great difference between
their corals and my own. Could you please provide me with some more detail on
these systems and any recommendations you might have.
<Mmm, this is all posted on WWM... a worthwhile addition to what you have, the
propagation tanks you may add...>
Finally, I would like to know what I could do to promote better base growth of
my SPS. They grow quite well currently but only seem to produce minimal bases to
support their structure.
<Provide slightly excess calcium, magnesium (check on the relative proportion
here) and alkaline earth minerals... "melt down" (in your reactor) proper
matter...>
All my Acroporas are thick and show signs of rapid growth on the branches but
not at the base. I am worried that if I try to fragment these particular corals
they may not produce adequate platforms from which to grow.
<This does happen... a valid concern>
I have learned that improper CO2 flow from my calcium reactor can stunt their
growth and cause excessive algae growth as well as improper lighting & water
flow.
<Yes>
Any information would be appreciated.
P.S. I primarily fragment out the following rapidly growing corals: Frogspawns,
Hammers, trumpets, torch corals, horn coral, pineapple corals, cactus corals,
birds nest coral, Pocillopora damicornis, and Staghorn Acropora (only for my
tank right now).
<Look into some high selling, fast growing varieties of alcyonaceans for your
new facilities... lordhowensis for your existing... Oculinids if you have
room... make adjustable trays in/for the new tanks, so you can have the colonies
near/er the surface... make a deal with your utility company to run your lights
at night... Bob Fenner>
Oz coral and fish farming 6/29/05
G'day Bob!
<Cheers, mate... Anthony Calfo in his stead>
I was hoping you could help me out. I live in Queensland, Australia and have
been propagating corals for a year or so now on the side as a hobby. I live
near the ocean so its quite easy. I've tried mostly Acropora, Sarcophyton,
bubble coral, and elegance coral. Also "trying" to breed mandarin fish with
mixed success! I've decided that I may start a small business raising awareness
on coral propagation and hints and tips to people in Australia on how do to it.
<Fabulous to hear... please let me know if/how I can help with this. I have run
a small coral farm of my own for more than a few years... have a look of it,
"Book of Coral Propagation" and have traveled to see. consult coral farms and
public aquariums on the matter. I do hope to see/help you succeed if I can>
Basically my question is do you happen to know any good Indonesian, Fijian,
Solomon islands or even Australian coral/fish wholesalers that you could
recommend?
<There are indeed some fab places... but what is the legality of you importing
them into Oz? >
I've been scouring the internet for ages and come
up with nothing ( which seems silly seeing as we have the barrier reef just
north of us!!).
<Indeed. But I do believe that Australia has a very conservative protection of
its resources... nothing in or out. As aquarists do yo not only have access to
Oz species?>
Any contacts you could give me I would be very grateful. It seems the whole
aquaculture/reef aquarium industry in Australia is very new and not as large as
the USA.
<Agreed>
Every online coral and fish mail order company seems to operate out of the
states but yet there's maybe one or two online retailers here in oz.
<Yes... reasons for this>
Any info you could give would be awesome - I'll shout ya a beer. None of that
weak American beer tho :P
<Heehee... a German friend of mine says that we do not have beer in America,
only yellow mountain spring water <G>. We actually do have some fabulous
microbreweries>
Cheers big ears, Steve - Sunshine Coast, Australia
<I'm wondering if you would not do best regardless to focus on unique Australian
species. You have some of the most amazing and sought after reef creatures in
the world in your seas. Do consider, mate. But regarding contacts... you may
want/need to get out once or twice per year for a proper investment in your
business education to see some conferences like AQUARAMA (Singapore) or InterZoo
(spring 2006 Germany). At such world trade shows, you will see all of the
biggest dealers of livestock, drygoods, etc all in one place. Very easy
networking. kindly, Anthony>
Oz coral and fish farming II 6/29/05
G'day Anthony!
<cheers, mate>
Thanks for your advice and help. I think you're right about me
concentrating on Australian species instead of trying to propagate
corals from the other side of the world. Seeing as I have the Great Barrier
Reef on my backyard I think that it could use a helping hand so it survives many
years into the future.
<Yes, indeed my friend. It is good business, good for the hobby and good karma
IMO>
I've actually ordered your Book of Coral Propagation as you can never have too
much advice, and you seem to be the pro in that area :)
<Ah... thanks kindly!>
Is this the best email to contact you on or do you have your own so every now
and then I can ask you propagation related questions?
Thanks for all your help!
<I spend most of my time here on such message boards. My personal e-mail is
badly neglected often so... so that we can keep up with the flow of mail from
folks in need>
Cheers big ears, Steve Wilson
<Rock on... Anth->
Removing propagated corals
Hi crew,
I hope you are all well.
I have recently added 3 cultured corals, a Xenia (Red Sea?), a millepora, and
an Acropora. All are thriving. Except for the Xenia, all are placed in
their permanent areas in my tank. I cannot stand the appearance of a "placed"
coral. The Acro and millepora are on rocks the size of half a fist, and have
spread onto the rock well. The Xenia (acquired last night) is skewered with a
plastic toothpick, floated slightly above a branch rock with elastics.
I would like to have these corals grow onto my own rock, as it looks more
natural. Is there any safe way to safely remove the entire colony from their
current small rock? I am letting the Xenia( my LFS owner said he has had
trouble propagating them) attach itself to the branch rock, for its own sake.
I appreciate this site, it has helped me for years. Since this is viewed by
the general public- Id like to plug two books. "Conscientious Marine
Aquarist" by Robert Fenner- an excellent book for starting reefers. "Book of
Coral
Propagation" by Anthony Calfo- I just started reading it-so far, so good-
great information( guess I'll be building a greenhouse!!).
Thank You! James <James, I've been in contact with Anthony Calfo on this. I
will paste his comments for your information. Thanks, James (Salty Dog)>
<Rubber bands are really a less than ideal means of
fixing corals. At best, some tolerate it. But for most
there is a better solution like gluing or epoxying
stony corals, impaling heavily mucous corals
(Cladiella colt, mushroom corallimorphs, etc)... and
in the case of most soft corals... stitching them (or
impaling them - toothpicks are fine).
In the case of Xeniids, the rubber band can be a
risk/danger. Xeniids have such tiny spicules and
integrity to their mass that the slightest infection
wipes them out fast (hours). And rubber bands or other
means of constriction (zip ties, crushing between
rocks, etc) stimulate excessive mucus which in turn
invites more bacteria, etc.
Other than a single stitch (with plastic
thread/fishing line)... simple natural settlement of
cut or loose divisions in a cup of rubble is fine
(cover with bridal veil temporarily if needed.>
