Breeding Amanos + intro

Dusko · Post by **Dusko** » Mon Jul 03, 2006 1:54 pm

Hi everybody,
and thank you Mustafa for such a great site

.
I was around for a while just reading your articles and forum topics, and I am impressed. I like your idea about preserving shrimp population and saving them from extinction.
Amanos are my first shrimp experience. I keep them since February this year. 5 of them, 1 male and 4 females. They had eggs all the time until now.
The reason for not spawning is probably my big re-aquascape. I removed all the C. thalictroides (Water sprite) and the gravel mulm was disturbed, probably releasing some gases trapped in the roots (with possible ammonia). All the shrimp stopped eating and would be on one spot for almost a week. One of the females was on her side, me thinking it's dead. But after a 30% water change they started acting better.

Any way, all the shrimps are back to life and behaving as usual again

.
The only thing is...they carry no eggs any more.

Recently, I tried, first time, to breed Amanos (Caridina japonica).
I failed

.
I am running a blog of my breeding attempt and I will link you to it (excuse me for not posting the whole thing but there is lots

)
http://caridinajaponicabreeding.blogspot.com/
I will rest on that subject for now, but am preparing a 10 gallon Red Cherry shrimp tank. I hope that my (in)experience in raising Amanos will help in future.

One more time, I am very happy we have such a site on the net

Kind regards, Dusko.

I just ordered a ton of amanos in order to kickstart my breeding attempts. I'll have them next week and hope to at least partly document it. So I guess we're in the same boat.

What method are you using?
I used the Heather Canderlaria method and to be honest it didn't work for me at all. Zoeas die after 4 days. http://www.gsas.org/Articles/1999/shrimp2.html

Next time I am going with the Mike Norens method that seem more realistic and has an illustrated proof http://mikes-machine.mine.nu/breeding_yamato.htm

Keep us up dated

BTW, I discovered one of my Amanos, this morning, carrying eggs again...o, man that feels good. And I was thinking that they will die on me

Kind regards, Dusko.

Dusko

Thank You for posting the links. There is alot of good reading.
Keep posting your progress.

I will soon be under taking the task of trying to breed the Amono's.

Between badflash's posts, the links you posted, and your link. This task will be alot easier.

I hadn't heard of the Heather Canderlaria method, but looking over the article I don't have much faith that she knows what she's doing.

I plan on taking advice from both Mike Noren and this person: http://caridina.japonica.online.fr/English/index.html

I haven't attempted it yet, but with all the amanos I ordered I should have ample opportunities.

Heather Canderlaria method...yeah

it didn't work for me and my shrimps.
At the moment I am busy but as soon as I can will go to get a 10 gal for breeding Amanos the way Mike Noren did have done it.
Of course I will write down my progress and illustrate it

Thanks for comments, it is a pleasure.

Kind regards, Dusko.

She obviously could not tell the difference between Caridina japonica and other Caridina/Neocaridina species. The first time she probably had C. japonica due to the floating larvae (although it could have been any other species with floating larvae) she is describing. The second time it was some other species with suppressed larval development (i.e. miniature shrimp).

This article was written in 1999 and it shows that people had no idea about shrimp back then (and many years after that). It's best to ignore this article.

That is the great thing about raising dwarf and other kinds of shrimp. It is so new and we are all involved in learning and discovering things about our shrimp. I am greatful we have the forum to share and exchange the experiences

. Have fun and shrimp on

I agree

! But what people like us should do is make our new progress available in written and illustrated form (like this web-site). Heather Canderlaria method is a myth or she had some other spp. which is more likely.
The other site that explains how to raise Amanos is this one written by Wilma Duncan. I don't think it is truthful and I will not try it but ignore it and rather put it on my "not recommended" list.
The only article I believe in, is the ones that are illustrated, like Mike Norens and the french one .
For example, there are so many old articles on the net that need update (BIG TIME). It is a problem with growing live plants also. Many articles explain how you don't need phosphates in planted tanks, otherwise you will have algae break-out. But in reality, it works the other way around

. Bring down the myths and up with the reality

.

Regards, Dusko.

Your instincts are correct. That article is worthless. Worse, I have told that person years ago that she is not breeding Caridina japonica, but she just ignored the advice and thought I was being "rude" for doubting here. Some people are just naturally stubborn. Here you can read one of my previous posts about her "article":

viewtopic.php?t=710

To this day she still has a picture of an amphipod (scud) on her website and labeled it as a "baby amano shrimp." Go figure....

Yes, those are good, realistic articles.

There are a couple people that have posted accounts of raising amano zoos using a combination of the two methods. I failed at using alternative foods, I tried to blend up some spirulina and let that go to no avail. When that female died I stopped trying. In the future, I want to cycle the SW tank by seeding GW 3 weeks prior to the zoos, use a sponge filter and carbon. I think the consensus down the road will be something very close to this.

To hatch and capture the zoos originally, I just put the pregnant shrimp in fresh water inside a 2L brine shrimp hatchery, with light aeration, one big bubble every few seconds. You have to give her a rock to sit on or she'll just go right to the bottom. I guess I got 100-300 zoos to work with about 5x straight. Reduce the water by very slow dripping (4 or so knots in the airline) and pour off the zoos, and dump female and and dont' sweat a few lost larvae back into the main aquarium.
