A source for Brachionus rotundiformis for feeding pearly
Jawfish larvae.
- 10/06/2009
Hi,
I have been searching for a source for Brachionus rotundiformis, the S-
Type rotifer strain. All of the online vendors seem to only sell the
L-Type strain (Brachionus plicatilis). Do you happen to know a place
I could order the S/SS strain from?
<Mmm, yes:
http://www.seahorsesource.com/cgi-bin/shop/search.cgi?&category=Foods-Live>
I am using them to feed Opistognathus aurifrons (pearly/yellowheaded
Jawfish) larvae. Also, would you suggest any particular enrichment to
feed the rotifers?
<Do ask the folks at Seahorsesource re... I would do a bit more looking
about in the scientific literature if this is an important project>
I lost my first batch of larvae either to fact that L type rotifers are
to big for them to eat, lack of nutritional value, or rotifer culture
contamination/crash.
Thanks,
Landon

Mandarin keeping- 2/27/04
Oh, thank you so very much for the
quick response. I did find some copepods in the Eheim filter and took
that out and tested the gunk and it was just as good as the tank, no
nitrates, no nitrites, ph, salinity everything just fine. <Great> So we
put that in the tank and the live copepods that seem pretty big into the
"breeder tank" I got a light on it, could only find a 10 gal size but it
will do. Will test water frequently for poor water and water change.
<Keep the water quality high, mate> Do you think I should clean up the
live rock by scrubbing some of the dead stuff off then? <Not a bad idea,
then siphon it out> I am not sure if the fish can wait until the rock is
cured as well as the time it takes to culture and obtain the copepods
which I hear is about 6 weeks. <Gonna have to!!> Can we buy already
raised copepods on line for a quick fix until ours are growing? <Sure.
Check out www.aquaculturestore.com (tell them Paul Mansur from
wetwebmedia.com sent you or try www.seafarm.com> Funny how the LFS
stores in town all sell these beautiful fish yet no one sells copepods
or culture kits. <Well, the fish likely eat frozen foodstuffs except for
the Mandarin. Some will except frozen foods though> The one my son
works for is giving us the stuff in the skimmer hoping that will contain
copepods. <Stuff I the skimmer???> They have 1 mandarin in their reef
tank, he is not for sale! But is apart of the permanent creatures they
care for in this reef tank that has coral for sale in. <Lots of stores
do this. Annoying ain't it?> We need food for the mandarin now any
suggestions to help him hang on until we can get the copepods growing, I
hear it takes about 6 weeks from the time you receive the kit. <Or more.
No guarantees either. Try frozen foods like mysids, Cyclops-eeze,
Artemia etc> The kit is for the 10 gal tank size, do you think it will
matter for the 5 gallon as long as we have enough food. <Limiting but
likely fine> Do copepods need to be fed phytoplankton, zooplankton and
such? <Yes. Also can be found at www.seafarm.com. Let Randy know I sent
you from Wetwebmedia.com>
Boy, this is a ton of work, it will be
worth it if the fish can come through however, anyone purchasing a
mandarin is nuts. <Agreed. I am not a supporter of keeping mandarin fish
in captivity> Unless they have everything it takes to grow copepods!
Again, I cannot tell you how appreciative to have your response, so
helpful, and so quickly. <It's what we do>
Thanks so very much.
<Thanks for being part of it all. ~Paul>

Plankton supplies 11/22/03
Hi guys, does anyone know where to
purchase a net for collecting wild plankton? I'm talking about one of
those long nets you tow or set in a drift. Thanks- D
<do try
Florida Aqua Farms (do a net search, or look in the bibliog. of our
books)... a fine place for such supplies. Else try biological supply
houses (like those used by science educators). best of luck. Anthony>

Growing and feeding pods
- 4/20/04
I wanted to start by saying that your site has saved me
hundreds of dollars and hundreds of hours of head ache...thank you!
<We appreciate your kind words and thank you for being here>
I
currently have a relatively new 46 gallon bow front reef setup. <How
new?>
Substrate = Aragonite
Live Rock = 50 lbs
Corals -
Alveopora, Star, Button, and Yellow Polyps, a Hammer and a Favites?
(Looks like a brain) All of the corals are small but I'm hoping that
they will grow with the proper lighting and feeding. <Will likely> My
goal is to do everything as naturally as possible. <Mine as well>
In
my new setup I used new Aragonite, but used the live rock from my
previous aquarium that had at least marine ich and probably
Brooklynellosis as well. <Hmmmmm> I want to run the new tank fallow as
long as possible to rid the rock/substrate of any lingering ich. <OK> In
the mean time I would like to be building up zooplankton and/or
microplankton for the corals and future fish to feed on. <Will come in
time without predation and a good source of live sand, live rock, and
maybe even an addition or two of copepods, amphipods and the like> I
have seen additives like PhytoPlex, but I can't imagine that plankton
bottled on a shelf for 3 months can be alive. <A really poor food
additive. I use and highly recommend any of the Reed Mariculture
products, DTs, BioPlankton for live phytoplankton sources.>
If
hatching brine shrimp and adding them, will they eventually reproduce on
their own within the tank? <Not likely. Usually need higher salinity and
no predation> I know that brine shrimp are the equivalent of potato
chips for fish, but that's all I've seen as far as live plankton in my
LFS. <Time to look to mail order, my friend> What can I do to provide
naturally reproducing plankton within the tank? <the above are good
choices for phytoplankton but be sure that the corals you currently have
in your aquarium (and the ones you plan to add) actually utilize the
food types you plan to feed. For other plankton and zooplankton sources
I highly recommend:
Sach's Aquaculture
www.aquaculturestore.com/index.html <rotifers, copepods,
feeder fish, live mysids, and much more>
Reed Mariculture
www.seafarm.com (rotifers, live/frozen phyto, copepods, and
live mysids>
Cyclops-eeze, frozen baby brine, and Golden Pearls are a
great form of zooplankton that most fish will take to. Give it a try as
well. We use these to raise seahorses and other hard to feed small
zooplankton feeders
A great question and I thank you for coming to
WetWebMedia with such a great question. ~Paul>
GETTING COPEPODS
TO THRIVE - 4/21/04
Thanks for the great leads on the stores. I
was looking to order "occope - LIVE Ocean Plankton - 500 ml.s - A
mixture of ocean plankton skewed towards copepods. Organisms from 50
microns - to 1000 microns in size." from
http://www.aquaculturestore.com/swinverts.html . <A great family run
business. As far as copepods go though, they don't typically do well
(reproduction et al) in the captive environment. I would lean more
toward the amphipod and Mysid population packs he offers. They are
omnivorous, prolific breeders, and generally hardy. The copepods are
intended more for either feeding to certain specialized animals or for
school science projects. They require regular feedings of phytoplankton,
and a steady and medium current. I feel that the amount of phytoplankton
required to keep copepods alive just long enough to feed to corals is
expensive and overly difficult. I feel it is not worth your time,
effort, or money> Live Mysis
Hello, <Hi again Scott>
I forgot to add on my last email but do you
know of how I can collect or purchase some live mysis or copepods. I
live in Canada so most places don't
deliver here.
<One place
that comes to mind is
http://www.inlandaquatics.com/. I know I've had a lot of success
buying this type of creature from them but there are many others I am
sure. One thing you might consider. If you have a local pet store or
friend who has some mysis or pods. Put a small piece of pvc in the tank
where they are and the Mysis or pods will use it to hide in. Then you
can collect it in a week or so and get some pods. Simply close off the
ends and dump it into a bag. Good Luck, MacL>

Mysid Shrimp
Hello there. I finally ordered the Conscientious
Marine Aquarist today. I have no idea what took me so long. Anyway,
about a year ago you guys pointed me to a website in Florida that ships
live mysids and other amphipods via Priority Mail. I searched the FAQs
for 2 hours and could not find the site (It isn't Aqua Farms). Do you
know of the website in Florida that ships live copepods and amphipods
via Priority Mail? It saves a bundle on shipping.

Culturing of sea urchin larvae - 02/16/2006
Hi Bob,
I accidentally found your webpage and hope that you might
answer some of my questions. I really would like to do some research
with sea urchin larvae.
<Gosh... a stock process/experiment back in
college...>
At my institute they have some experience in
reproduction of sea urchins (Psammechinus miliaris). And I also have
support from a technician who has lots of experience in culturing marine
organisms. I myself worked with fish - quite different stuff indeed.
Nonetheless, I really would prefer to work with larvae instead of
embryos. Indeed, I was told that larvae culture is quite laborious. Do
you have any experience with invertebrate larval culture????
<A bit>
How elaborate is that? What equipment do you need?
<Mmm, some brood
stock, mechanism to bring on gametogenesis, spawning... rearing tanks
(sometimes specialized) and "good" water... new/natural or
recirculated/filtered>
And what about the feeding?
<Very
important... Often the single largest "stumbling block" in invertebrate
culture. A computer search here saves much trouble>
I won't be able
to maintain an algae culture as feed for my cute larvae. But I heard
that there are commercially available microalgae. Indeed, I read a
publication that larvae don't reach the same growth rate with a
commercially available diet compared to a control diet with Dunaliella.
And do you know anybody who could give me more tips???
<Sea Biscuit
in the Seventh... Actually, there is much written/recorded re many
species, groups... time to go to "the library"... and ask specifics
later>
Thank you very much!
And best wishes from a future sea
urchin culturist! :-)

Fish stuff... in the biz? Fish foods,

Please do not reply to
this email address.
<Okay>
Greetings,
I have been reading a
lot about live foods recently and find lots of places that are willing
to talk about cultures and how to harvest but few if any that sell
cultures - or better yet have a way for me to create my own cultures.
<There are a few... look at the back of current hobby magazines...
Tropical Fish Hobbyist, Aquarium Fish Magazine... and the "Biological
Supply Houses"... e.g. Carolina... offer such... or ask about at a local
large college that has a biology department... Often these folks will
give out such>
My wife and I have a small fish farm with about a
dozen different varieties of fish and have been doing fairly well in
breeding and
growing babies but are at a loss as to where we can get
live food supplies.
<! You're in the trade? Do contact Randy Reed
(Reed Mariculture... .com) re help here... San Francisco Bay Brand and
SaltCreek re Artemia... Argent Chemical re Cyclops... Piscine Energetics
re Mysids...>
We do much of what we see others do simply because
what works works and we don't have to trip over our own stupidity .....
as much.
<... Time to encourage you to get help with searching the
literature... not hard to do... And no need for you to "re-invent the
wheel"... much information of use is available...>
However, it is
difficult to find good food for fry, good food to feed those getting
ready to breed and in general good food.
<Mmm, not really... just
takes a bit of searching, contacting the folks who can/will supply this>
Currently we rotate through several dry foods and frozen
bloodworms/brine shrimp which keep the fish pretty healthy. The problem
is that dependant on species we need different types of frozen or live
food and some of those are hard to come by.
Any suggestions on food?
Also - we run several different types of filtration and I am
contemplating do a cross between individual tank filtration and
everything going through a central system by simply doing it by species.
<Lots of benefits...>
Right now our under gravel filters work great
and I have no problem with them except for the amount of power needed.
Thoughts on this?
<...? Posted on WWM... Start here:
http://wetwebmedia.com/AqBizSubWebIndex/cntfiltbiz.htm
and the
linked files at top...>
Lastly - any ideas on the best way to
increase business?
<You're not joking? Please see the Business
Sub-Web that's part of WWM>
We have a few pet stores and a few
individuals lined up as buyers but as every business owner will attest
to - there aren't enough customers in the world. Any way, I ask this not
for reasons of advertising, but rather trying to market towards a fish
interested market (and I haven't found that small magazine ads work).
<They don't in the short/er term... Best to establish local to further
outlet relations, and build on these... Minimum orders, arranged
shipping schedule, rates... Contacts through word of mouth, visits...>
Ideas? I know what I think but always looking for a sounding board.

Amphipods For Free...Too Good To Be True? 6/23/06
Hi
there,
<Hi there! Scott F. here today!>
I have a quick question.
A while ago I had to treat my 29 gal. for saltwater ick. During the
isolation there were no predators for the pods that I had and they
flourished. There were hundreds of them everywhere swimming around.
Because of this I had thought it a good idea to purchase a mandarin
Dragonet. Unfortunately, with the reintroduction of the fish, the
numbers of pods have gone down significantly. I'm now afraid that the
Mandarin might starve. I was wondering, since money is a little tight,
are cold water 'pods similar to warm water ones? I was thinking it would
be easy to just capture some of these guys and set up a breeding tank
for them. Would it be alright to feed these guys or not? From what I
remember they look almost identical to the pods in my tank now. Any feed
back would be appreciated.
Shawn
<Well, Shawn, you ask an
interesting question. I'm sure that the temperate amphipods are similar
in nutritional value to the tropical ones, but I have another concern:
Introduction of wild-caught amphipods (tropical or otherwise) is
potentially a vector for disease introduction. Personally, I'd rather
seek out a captive source (such as Reed Mariculture or Ocean Pods- do an
internet search), where you're assured captive-propagated, pathogen free
creatures. As an alternative, 'pods collected from a fellow hobbyist,
who's healthy tank has a well-established population, would be a better
source. Hope this helps! Regards, Scott
Rotifers... cult. 11/29/06
Hello again,
<Hey Tom, JustinN with you tonight>
I have been reading on your site
and other sites about what the best things to feed clownfish fry are,
and one thing that keeps coming up is rotifers. I was wondering if you

Frozen Rotifers as a Replacement for Live Cultures? - 09/09/06
Hello Ladies and Gents.
<<Hey Amanda!>>
Hope whoever gets this
is having a fine day/night.
<<So far so good <grin> >>
It seems
I have yet another question that I'm hoping someone there has an answer
to.
<<Let's find >
For a bit of background. I've been breeding
my pair of black morph of Amphiprion ocellaris for about three years
now. I have had great success doing the age old green water rotifer
culture then feeding the rotifers to my hatchlings.
<<Okay>>
Never really thought about how much time I put into maintaining these
cultures, until my fiancé gave me a colt (as in a little baby horse).
<<What?! Another hobby/interest that's not aquatic related!!! Just
razzing you Amanda... What you say is true...my wife tells me I spend
way too much time with my reef, and not near enough doing chores/working
around the house. Hmm, maybe that's not quite the same...>>
No
don't get me wrong, I was tickled pink when he gave him to me, and I
love him right to death, but I just don't seem to have enough time in my
day anymore.
<<I do understand>>
(Just in case you wanted to
know how my day goes) I get up at 5:30, walk the dogs, check on and
generally potter about with all the fish tanks, shower, drive to work
(this all happens before 7:30). Work from 7:30 to 4 usually skipping
lunch to try and get everything done so I can make it home to potter
about with the green water/rotifer cultures.
<<Hee-hee!>>
Pick
the fiancé up from work at 6 drive out to the property, feed brush and
train my colt, get back home round about 8:30ish and pick up some nasty
disgusting fast food on the way (I HATE FAST FOOD). Walk the dogs, wolf
down my now cold nasty disgusting fast food, and if I'm really lucky I
make it to bed by 11:30. This has been going like this for about 2
months now and I'm EXHAUSTED!!
<<Mmm, I think I see the
problem...you need to find a fiancé that can drive and cook!>>
Just
in case you thought I could sleep on the weekends, oh no, I can't.
<<But of course not...>>
My weekends are just as full. So now that
you know more then you ever wanted to know about my life I'll get to the
question.
<<Thank you for sharing <grin> >>
It got to the point
where I was going to stop my clownfish breeding. I just couldn't find
enough time in the day.
<<Mmm, yes...decisions>>
Then it hit me
FROZEN ROTIFERS!!!!!!
<<Indeed! I feed these to my reef tank
daily>>
And I want to know if my plan might just work. My clownfish
larval tank is circular so there are no dead spots,
<<Ah yes, and no
sharp corners for larvae to be trapped in...smart>>
I have a slow
pump (fine filter mesh over the outflow so I don't lose my little fish)
emptying the tank from the bottom going through all the filter media
pumped up into a trickle filter resupplying the tank diagonally from the
top so as to produce circular turbulent flow.
<<I see>>
Now if I
rigged up a slow drip container with bubbler filled with frozen rotifers
(that was surrounded by a sheath which could hold ice to keep the
rotifers from going off) that dripped into this tank would the larval
clownfish hit the rotifers or do they feed on a motion response.
<<Mmm, a good point/question...but one I think you'll only answer with
some experimentation>>
And if they feed on a motion response would
the circulation in the round tank keep them suspended for long enough
and provide enough turbulence to give the rotifers a semblance of
swimming to entice the larval clownfish to strike?
<<Is
possible. You may also want to consider adding a bubble-wand along the
bottom of one long side of the tank. This would provide a "gentle" flow
pulling water (and rotifers) off the bottom and pushing to the top where
it "rolls" across and down the other side to be pulled back across the
bottom and then back up again. This is a method used on DIY "Kreisal"
tanks>>
Is it possible will they take the frozen rotifers so I won't
have to maintain my green water and rotifer cultures anymore? Or is it
bye-bye to baby clownfish??
<<Hard to say...but worth a try I
think. The only real downside I see to this is the possible fowling of
the larvae tank from an excess of frozen (dead) rotifers in the system
due to the high rotifer-to-larvae ratio required for successfully
raising the fry. Maybe turning off all flow will allow the rotifers to
be drawn to/collect on the filter screen for easier removal>>
Thanks,
Amanda
<<Happy to assist. EricR>>
Re: Frozen
Rotifers as a Replacement for Live Cultures? - 09/11/06
Hey
EricR,
<<Hey Amanda!>>
Hope you had a better/more relaxed
weekend then I did.
<<Mmm...cleaning 1800sqft of deck in preparation
for staining...still...better than being at "work"...>>
I hadn't
even thought of a bubble wand. It certainly would add that extra
current to keep the rotifers suspended for longer.
<<Indeed>>
I'll have to work on getting it all set up this afternoon and give the
frozen rotifers a try.
<<Excellent...worth the
time/experimentation>>
I'll let you know how it goes if you want.
<<Ah yes, please do...and of course will post for others' edification>>
After this weekend the green water is gone. Spent all weekend fighting
a bush fire, didn't sleep much, all my rotifers died :( and I lost a new
batch of clownfish :(
<<My condolences>>
And just to add in a
bit of a rant. People who purposely start bushfires SUCK!!!! They need
to be tied out with all the poor animals, wild and domestic, to get
scared, scorched and possibly burned to death right along with
them. DON'T START FIRES. FIRES ARE BAD.
<<Is sometimes hard to
fathom what motivates people...>>
Oh, and the Fiancé does drive,
it's just at the moment neither my car nor my bike is working, so we're
down to just his Ute. As for cooking, he's done that once or twice, I
very politely ate it, then ran to the bathroom gagging. Cooking is not
his strong point.
<<Hee-hee! Obviously he has other redeeming
qualities <grin> >>
Thank you
Amanda
<<I look forward to
hearing about your results. Eric Russell>>
Pod culture 6/21/07
Hello, crew.
<Hi Dan, Mich
here this morning.>
No question today, just some feedback.
<Always appreciated.>
We have a psychedelic mandarin in too-small an
aquarium (three-year-old 46-gal with perhaps 50 lb live rock). It was
fine for a while, but has slowly gotten skinnier (over the course of
months). We investigated buying "pod cultures" online, but they are
pricey. Then I ran across this gem on WWM:
"Can I encourage you all
to start a marine "pod farm". It is very easy. I have a 5 litre mineral
water bottle with 4 litres of my tank water in. I bought two inoculums
from www.reefworks.co.uk and stand the whole thing on my south-facing
windowsill in my workshop. 3 weeks later I had a mass of pods all
zipping around like mad. They are very un-demanding, I give then a level
teaspoon of plain flour each week to supplement their diet of algae and
detritus. Put an airline in and let nature take it's course. Now, each
week I give the bottle a gentle shake and pour two litres of the mix
into my tank and replace it with two litres of pristine indo-pacific
from the tank. A week later the pods have made up their missing numbers.
I do this at night so the pods can get established without the Chromis
getting in on the act - they love them too."
I have done this using
an EBay pod culture as a "seed". The explosion in their numbers is
astounding (my two-liter bottle has many thousands of pods after a few
weeks). We are going to upgrade to a larger "culture container", and I
am confident that we will be able to fatten up our mandarin and provide
it all the food it could possibly want.
<I am very happy to hear/read
this. Your Mandarin thanks you, and we, WWM, thank you for being
conscientious.>
FYI -- we keep the "pod farm" in our stand, next to
the sump. The temperature is "stable enough", and they certainly don't
seem to mind the low light under there. Just a pump with air, and
changing half the water every week. Easy as 3.14.
<Heehee! I love the
math geek reference!>
Dan
<Dan, thank you for sharing your
experience here. Others will benefit from this. Life to you and your
Mandarin! Mich>
Re: DSB
move? Mysid culture 10/22/07
Hello again,

I need to clarify my DSB move question. I want to move this DSB into

Also on the Mysid shrimp question, which way would be better to

are more nutritious, cost-effective>

Breeding saltwater feeder shrimp – 5/3/08
WWM Crew Member,
I have searched all over the internet to find info
on breeding the Saltwater Feeder Shrimp, Penaeus sp after reading this
on a seller's website:
If kept in sufficient numbers and fed well (a
mix of flake food, frozen Brine, and Spirulina should do fine), they may
begin to breed. Females carrying eggs should be transferred to a
different aquarium (or a partitioned section.) Basic fry food may be fed
to the newborn shrimp. These tank-bred shrimp are USDA certified to be
free from potential diseases and pathogens.
Unfortunately, I can't
find any more info than that or have found anyone that has tried or been
successful with it.
<Mmm, has been done many times, places... and the
family (Panaeidae) are a HUGE fishery/aquacultured world-wide...>
This is what I've been considering so far: 10 gal tank with air bubbler
critter keeper or enclosed area for shrimp with eggs (not sure how to
enclose area so water moves through, but fry do not)
<See the site of
Aquatic Ecosystems... for fabrication ideas or purchase of such...>
I'm not sure about algae to keep with them or food for the fry. Would
crushed flake, phytoplankton, rotifers, or Cyclopeeze work?
<...
likely so>
I really appreciate you taking the time to answer. Thanks!

Matt Wittenrich/Microcosm-TFH... There is much written on the topic of
use... but, you can also employ trial and error... Bob Fenner>
Culturing Live Food, 7/9/08
I am looking for guidance on
culturing live food. Doing such is driven by interest rather than a hard
requirement from my tank's inhabitants. I have a 24 gallon nano-cube
(which I wish I had never gotten since it provides no flexibility
whatsoever. A little bit bigger system with a sump/refugium would have
definitely been the way to go. but I digressed).
<I think many people
find this to be true once they get their tanks going.>
The tank has
been running for 2.5 years, and it houses 2 Percula Clown fish, 1 small
Pipe Organ coral, 1 small colony polyp, and a couple of dwarf crabs and
snails.
The clown fish readily accept flake foods and seem happily
fed. On rare occasion I have fed them newly hatched baby brine shrimp
which they loved.
Also, the tank does have copepods that came in from
the live rock. The clown fish hunt the copepods, but the copepods mostly
hide in the live rock and substrate. The copepods are also very small,
being barely visible to the naked eye. Usually it requires a 30x eye
piece to get a good look at them.
<Eye strain for sure.>
There
seems to be a couple of choices of easily cultured live foods: brine
shrimp, copepods (larger Tiger pods and smaller Harpacticoids pods),
rotifer's, and Mysid shrimp. The live food(s) would be cultured in a
dedicated vessel. My questions are as follows:
1) Is anyone of the
cultured foods listed above more useful than the others given my tank's
inhabitants?
<The pods and Mysid by far.>
2) Would introducing any
of cultured foods 'live' be harmful for the current tank's population of
copepods? It is my understanding the Mysid shrimp are voracious and
would likely not only consume the current tank's population of copepods
but also would likely consume each other. I want to feed the tank, not
establish a new biological order.
<More likely it would strike some
sort of balance eventually, but how many Mysid could survive long term
is hard to say.>
3) Culturing brine shrimp to adulthood would require
that they be enriched before feeding them to the tank. would this be
worth the effort?
<Not in my opinion, easier to just feed the fish
the food directly, the brine itself adds almost nothing.>
4) Should
brine shrimp eggs be de-capsulated before hatching them? Asked another
way, can adult fish eat them with the shells still attached or is
this just a concern for fish fry?
<Mostly a concern for smaller
fish.>
5) Would the soft corals benefit from the addition of any of
the listed cultured live foods?
<Probably marginally.>
Thank you
much for your guidance.
<I highly suggest checking out the works of
Dr. Adelaide Rhodes, she gave a great presentation at this year's IMAC,
and is an expert on what you are trying to do.
