- Breeding Harlequin
Shrimp - Hey WWM crew, it's me again... <JasonC here...> umm... I
was wondering, since you don't have info of harlequin shrimps, except
for the FAQs... do you know any good site that have info on them? <This
is one of the only ones I've ever found:
http://www.sihawaii.com/sydkraul/harly.html > sites that talk
about breeding and all... thank you Sokha <Cheers, J -- >
Harlequin Shrimp Update 8/3/07 Hi there, <Hello Syd> I was
reading your information page on harlequin shrimp
http://www.wetwebmedia.com/clnshrpfaqs.htm I am raising and selling
these shrimp ( you refer to me when I did this at Waikiki Aquarium, but
I now have my own farm). Your answers to people seemed good to me. I
can assure you that the shrimp eat pieces of frozen starfish, and seem
to do fine on dried starfish. I use only crown-of-thorns stars, for
political and cost reasons. Because they are large, it is not good to
stick the whole star in the shrimp tank. It is ok to do that with small
stars. Anyway, if you want to use any of the info on my website, feel
free to do so. <Interesting, and thank you for sharing. Will post for
others to see. James (Salty Dog)> Syd Kraul

Re: Question on Harlequin Shrimp... Price Gouging... No, Supply and
Demand... What the Market Will Bear... Future Breeding Efforts... A
$A350 Purchase! More breeding thoughts... 9/5/07 <Ray, my
friend! Mich with you again.> WOW .... what a wonderful resource
to get started with. He certainly provides some valuable knowledge
that would only otherwise come by doing it yourself firsthand. I
think that if I can get my guys to produce eggs, I will be "up
there" very quickly. He mentions several things that I had already
guessed at, but he provides infinitely valuable info that would
otherwise take ages to figure out on my own. So thank you (and
thanks to Brenda too), for such a great page. <You are welcome!
Must credit Brenda here, was her find, she though it would benefit
you.> I didn't realise you had such an adverse reaction to
Harlequin feeding habits, and I promise not to mention it again.
<Yeeaah... I've gotta couple of issues... perhaps about same number
of issues as National Geographic...> I used to live in an area
right on the coast, with coral gardens only a short walk from the
beach at low tide, <Ahh... heaven :D > but I have since moved
too far south, and the reef flats I used to frequent are now 1000
miles away. <Now why would ya go and do that?> I still live
just a short drive from fresh seawater though, so collecting fresh
water and copepods is no problem there. <I think this will be a
great benefit to you and your new babies!> My new little
companions lack the large luminescent eyes of cuteness,
<Heehee!> but they have much greater appeal to me than that.
<Ahh, good!> I find myself sitting and watching them for hours,
totally awed by their graceful beauty <The underwater world
holds some amazing things... can hold ones attention for hours if
allowed.> (and the fact that I can't believe I have them).
<I'm pinching you! You are awake!> I do water quality checks
daily, but I am sure that will settle down when I finally get used
to seeing them every day. <Heehee! A bit of an overprotective
parent are we?> I'm still in shock ... but it will pass.
<Heehee! Yes undoubtedly.> The journey has already been
thrilling, so I can't imagine how good it will get should I be
successful in breeding, and raising even a single one. <As I
said before can be a journey of highs and lows, but hopefully more
success than heartbreak.> I think there is much joy to be had in
the successful accomplishment of each step, <Assuredly!> and
if I can do something small to contributing of captive bred species
around the world, then I will have paid my dues for all the wild
stocks I've kept in the past. <Each step makes a difference.>
Here's to hoping. <Cheers! I'll toast to that!> Ray.
<Wishing you all the best my dear friend! Michelle>

A $A350 Purchase! More breeding thoughts... 9/10/07
Lovely Michelle - <Precious Ray> Glad to know I'm not annoying
you too much. <Nope! Not at all.> Charles contacted me and we
have e-mailed a few times since I wrote you last. <Oh, Terrific!
I am glad to hear this!> He says that I am the only other person
he knows of that is attempting to breed these creatures.
<Really!?!? I am quite surprised by this, perhaps there are others
who are just not "vocal". Have you searched other forums,
ReefCentral etc?> No one else has contacted him through his page,
<This I can believe. Was a challenge to find his email on his site.
Perhaps better email placement may encourage more contact.> and
we are going to keep in contact regarding our efforts, <Very
good!> and see if we can figure it out. <Often two heads are
better than one.> The biggest problem we face it seems is feeding
the larvae. <From what I've read, does seem to be a challenge,
finding appropriate and small enough foods. Not knowing the natural
diet is a challenge.> Once we crack that, we will be world famous
breeders of Harlequins... <Hey, ya never know! Could be your 15
minutes of fame! You should at least be able to get published! I
want an autographed copy! ;) > I am trying to condition my guys
by providing a completely stress free environment (including stress
by less than perfect water quality), <Good.> and plenty of
their favourite food (which I won't mention). <Heehee! Thank
you! Much appreciated!> Also, I am taking into consideration
other factors often overlooked such as temperature range (and/or
variance) plus water movement, as these sorts of things are often
triggers for breeding behaviour. <Yes and the phase of the moon
is often quite an important breeding queue as well.> I will get
more information from Charles, regarding conditions on his tanks, so
that should go a very long way to getting them producing eggs.
<Yes, to have someone who has had some degree of success will be
most helpful. You should be able to help each other quite a bit.
There are others out there who may be able to assist.> Once I get
them happy enough to produce eggs, half the battle will be won,
<Yes.> but the most challenging part will begin. <Absolutely.
Raising the fry is challenging to say the least!> I have no
delusions of getting it right straight away, but if I can have even
limited success before they get too old, I will be happy. <Ahh,
good.> Tons of gratitude to you once again, <Glad I could be
of help! Please continue to send updates.> and if you were close
by, I would hug you. <I always appreciate a hug! Michelle>
Ray. Re: question on
Harlequin Shrimp – 09/05/07 <Hello Charles and Linda, Mich
from WetWebMedia here.> Thanks, it was very nice to see the
effort I put into that page was of use to someone. <Likely more
than you know! I thought you might enjoy seeing. This will be posted
on the www.wetwebmedia.com website which averages around 20,000
unique visits per day, more than www.reefcentral.com so hopefully
more will find their way to the wealth of information you have
provided. Thank you for your work here. Mich> Charles & Linda

Darling Michelle - <Sweet Ray> I really, really love to write
to you, but please let me know if I am wasting your time. I don't
wish to become a burden on your time, so you must tell me if you are
too busy. <Not currently...> I just wanted to let you know
that I have e-mailed Charles and Linda to thank them for their page
on Harlequin breeding, <Very thoughtful of you. I'm sure your
kindness will be meaningful and appreciated.> and thank you and
Brenda for sending me there. <You are quite welcome and I have
informed Brenda as well.> You asked me why I moved so far away
from my coral world ... The answer is life. I needed to get out of
the small town I lived in, and find a life with better
opportunities, so I move to our state's capital. <Ahh, yes, I
can very much relate and am making strides toward such a move
myself... but hopefully towards the octopus' garden, not away.> I
can tell you that had I not moved, I doubt I would be e-mailing you
now ... so it's all a progression, <Yes, I understand, growth
and change are indeed good.> as it will be with breeding "my"
Harlequins. The first thing to do is set up a tank to raise the
larvae in while mom and dad are settling in properly,
<Acclimation and time is good> and then try to condition them to
produce eggs. <And just how you gonna try to condition them to do
that? Heehee!> So .... here goes ... <Are you ready?> It
all begins ... <Excellent! As Confucius said: "A journey of a
thousand miles begins with a single step."> *Hugs and Gratitude
for your support* <Thank you very much Ray, been a while since
I've received much of either and they are appreciated. Michelle>
Ray.
Re: question on Harlequin Shrimp – 09/14/07
Beautiful Michelle - <Dearest Ray> My little Harlequins seem
to be very shy. <I'm sorry. Makes it more difficult to enjoy
them.> They rarely come out of their cave, so observing them is
often difficult, <perhaps more time to acclimate will help these
guys get more comfortable.> but they seem happy enough, and
feeding well. <Oh good!> Water quality is spot on, so all I
can do now is wait. <Time and patience...> I've only had them
a week and a half though, so I may have to wait a while yet.
<Yes, Hopefully they will become more secure and outgoing with
time.> I don't think the food issue for the larvae is the biggest
problem. <No, I didn't think so either from what I had read on
the DIBS board, the unexplained deaths are more concerning in my
opinion.> Charles seems to think that his water quality has been
to blame for all the losses of larvae, <Again from what I read,
this does seem like a reasonable/logical conclusion.> because he
has observed them feeding ravenously on copepods in his rearing
tank, but he just can't get them to live longer than 7 days.
<Could be something else as well.> The water quality issue may
well be true, <Yes.> but he is awaiting a new batch, due to
hatch any time now, <Excellent! Please keep updating.> so it
will be a big leap forward if he can make it work this time, even if
it's just a few. <Oh! Yes! Most definitely!> I intend to do
things a little differently to Charles, <Trial and error...
doing things slightly different is called experimentation ;) and is
often how we learn and at times succeed. Just document what you do
and how you do it.> but he has found a suitable food, <A
large obstacle to overcome!> and I'm hoping he has more success
this time. <Me too!> The challenge is worth it, <I'm glad
you feel this way.> and I'm just excited to have mine produce
eggs at this stage, but who knows if and when that will be. <One
hurdle at a time.> You know a little about what makes me tick, so
what's your interest? <After many years of longing I was
recently certified to SCUBA dive and I have much enjoyed doing this,
though I'm not doing it as much as I would like. It is wonderful to
see so many of the creatures I am familiar with, in their natural
setting... and the "tank" maintenance is so much easier ;) I am also
quite a passionate above and underwater amateur photographer. I have
much to learn in this area. I enjoy traveling and have been quite
fortunate to do quite a bit this year and hope to continue this
trend. Perhaps making it to your country at some point in the not
too distant future, I would really love to see the GBR. My father
spent over 33 month in the South Pacific including Australia, New
Guinea, the Philippines and I believe he made it into Japan as well
fighting in WWII. So I grew up hearing many stories about the
wonders of your country. My first "research" paper (in 6th grade
mind you) was titled The Marsupials of Australia. I also enjoy
interior decorating; swimming, actually diving more so; hashing,
running of sorts; spending time with friends; helping and sharing
with others; and philosophizing, laughing, and chatting with
interesting people.> Do you keep marines yourself? <Barely...
my tank is more of a nuisance algae farm at the present moment. I
hope to be relocating soon so it has been rather neglected....
Michelle, hanging her head in shame...and grateful that no one can
see her tank.> Ray.
Re: question on Harlequin Shrimp 7/21/07 Dearest
Michelle - <Hi there Ray of sunshine!> It's always so nice to
hear from you, <And you as well... brightening up my day!> so
I thought that I would include a small picture of myself for you to
put a face to the letters. <Ah, yes, thank you. It is indeed nice
to put a face with the name. We, the crew, are familiar to many, as
most of us have our pictures posted on the meet the crew page. I am
just returning from an international conference, MACNA, which was
held over the weekend and it is always surprising to meet some of
the people who I have heard about or corresponded with on-line. You
never know what to expect.> Bad news about Charle's Harlequins
I'm afraid. <Uh-oh!> He did a too hasty transfer to his
rearing tank and they all died from not being acclimatised properly.
<Darn. A shame.> Sad news, but his Harlequins have eggs every 3
weeks or so, so he won't be waiting too long to try again. <This
is good. Charles's name came up a couple of times in presentations
at the MACNA conference over the weekend. Took me by surprise. I
actually saw some pictures of some of his tanks! How funny is that?
I was like wait, I know that name! Also attended a lecture on
breeding and micro-foods. You and your little shrimp were first and
foremost on my mind.> I on the other hand have not had so much
luck as yet ... (not that I was expecting any mind you). <Yes,
sometimes low expectations can protect our wellbeing.> One of
them did shed for the first time though, and I suspect it was the
female because she has been hiding completely out of sight for 2
days now, and didn't even come out of hiding to try to grab the new
food I put in their tank today, but left the little male up to the
task. She got involved only when it was safe in the hole they live
in. <Well at least she had a safe molt.> I hoped that she may
have been protecting new eggs (as I have read they will do), but she
isn't carrying any yet, so I suspect it is because she still feels
too "soft" after shedding to come out. <Likely so.> Thank you
so very much for the personal info. It's great to know something
about you, and I think we are very similar with regards to our
diving history. <Oh, I only wish. You undoubtedly have many,
many more dive than I do, likely several magnitudes more.> I
learnt when I was just 19 (geez ... that's 20 years ago now), and it
was about a year and a half to two years after I started keeping
marines. <With over 20 years of experience keeping marines why
aren't you writing on WWM?> Ultimately, I learnt to dive because
I wanted to see what I was keeping in their natural environment, so
I could better take care of them, <I actually wanted to dive
before keeping an aquarium. If anything, I started to keep an
aquarium as a means to satisfy this urge.> plus I just wanted to
experience the thrill of diving a coral reef, <Initially, I
would have been happy just being able to be underwater for a
prolonged period of time, just to see what I could see. Now I'm a
little more spoiled. I want to be in warm, clear water, with a
camera.> and I got hooked like I never thought I would. <I'm
hooked, but I can't say I'm surprised. I have always loved being in
the water.> I spent the next 8 years in the diving industry,
<How awesome!> eventually becoming an instructor (though I
haven't taught for a long time now), but it still thrills me to get
wet and see what's under the water. <It's a whole different
world. I love it! Though, I can hardly bear to go without a camera.
I love seeing what images I might capture.> Some of my happiest
memories are the times I sunk to the bottom of the reef after a few
weeks away, and looking around, feeling like I was home again. <A
wonderful feeling.> My mum (sorry ... mom) always said that one
day I would find a mermaid and never come home again... Well... I
never found a mermaid, but I still keep my eyes open for one...
<You may still find her.> It would be an experience of a lifetime
for you to come out here and see the GBR. <I would absolutely
love to. Is one of my life goals.> I can definitely tell you the
best places to go, and who knows ... I might even come with you to
see the places I love and haven't seen for so long. <That would
be wonderful! This is the best way to do it, with an experienced and
knowledgeable friend.> Much hugs. <And to you!> Ray.
<Keep updating! Mich>
Re: Question on Harlequin Shrimp – 10/04/07 Michelle :
<Hello my friend> I hope you get this in time ... <I did, but
just barely! I leave in 3 short ours from now!> I write, feeling
very much like an amateur. <Uh-oh!> I went out last night
(Wednesday) and got back rather late. I used a flashlight to check
on my shrimp before I went to bed, <Tuck them in!> and the
tank was a mass of larvae. <WOW! YAY! I'm so happy for you!> I
couldn't figure it out at first, because I didn't even know she had
eggs, but after a closer examination, I found them to be shrimp
larvae. I was both gleefully surprised and pitifully ashamed at the
same time. <Heehee! Mixed emotions indeed! But a fantastic
discovery!> I check the female nearly every day for evidence of
eggs, but I never saw them. How foolish I feel, but how excited for
the future. <Heehee! Great that they are reproducing so soon!
Well, it would likely help to know exactly what the eggs look like,
which I doubt you've seen before and you may not really know what
you're looking for until your little guys have had a couple of
spawnings. Pictures help, but until you've seen such with your own
eye... But this is wonderful news! I am much looking forward to your
updates! Feel free to write as I'm gone thought I won't be about to
respond for a while. > It looks like those links will be coming
in handier sooner than I thought. <I guess! Glad I could get them
for you!> Enjoy your trip, <I sure hope to! I am very much
looking forward to being in the warm, clear, water with a camera!>
and please take care, and be safe. <Thank you Ray. I appreciate
your concern. Looking forward to hearing about the future
developments! Hugs, Michelle> Ray. |
