    Ninja Shrimps Spawn

    Hi guys,

    my ninja shrimps spawned, can see very small little fries with a sag attached to them floating around the water. I think its undergoing a planktonic change. But i guess the fries require brackish water or saltish water to survive. Thus metamorphosing into post-larvae and assuming a benthic lifestyle is more important. My tank does not have the two required conditions. I doubt the survival rate is high but just hope for the best. Anyone who has bred them can share any experience?

    I have atttached some pictures of the ninja shrimps.








    cannot manage to take pictures of the larvae, but saw an online picture, the larvae looks similar to that of yamato shrimps.

    "cherry, bee, tiger and cyrstal all have no planktonic stage , ie they release small shrimp from the egg's carried on the swimmerettes

    this makes these shrimp infinitley easier to breed as no special rearing tank is required and feeding of the young is less involved

    amano, as has been rightly pointed out, along with other shrimp have a planktonic lifcycle that requires (and there seems to be two variable schools of thought here) an increase in salinity gradual... as they would naturally drift down stream toward the sea from marshy fresh waters

    these small planktonic stages(much like brine shrimp) also need microfoods algae/bacteria etc

    after a period they moult and become shrimp shaped and swim back toward fresher waters

    obviously much more involved for the latter

    andrew"

    No wonder the high price! It is rare and breeding it might be harder than cherry, bee, tiger and cyrstal.

    Interesting website: http://caridina.japonica.online.fr/English/Elevage.htm

    The price is high, not just solely because of the conditions in breeding them, otherwise Caridina multidentata (Amano shrimps) should also be expensive by the reasoning.

    It helps when the shrimps show strong colours and has variable patterns, aquarists are more willing to fork out the money for them.

    BTW, as far as I know, C. serratirostris larvae requires brackishwater to survive. So you would probably need to increase the salinity of the water.

    However, I have not really seen any specified parameters of successful breeding, so this may be quite a difficult task.

    ACtually ninja shrimp were out long ago in singapore...and the price was not so expensive.. i believe once it droped to only less than 40% of what it is now... perhaps with the current "shrimp craze"... they decided to release it again and restore the old price.... funny...because they don't breed or can seldom succeed at breeding in fresh water...unlike CRS..
    That simply translates to an investment with no possible returns without further additional investment and efforts.

    i do not have a chiller, but i don't mind setting up a brackish water tank. Will it work?

    You can try the method used on C. multidentata (Amano/Yamato shrimp), but there seems to be some problems with Mike Noren's site.
    http://mikes-machine.mine.nu/breeding_yamato.htm

    However, as mentioned before, I have heard of many failures in breeding C. serratirostris (ninja shrimp) and have not seen any specific parameters of successful breeding.

    You would have to experiment a bit, either move them to a brackish water tank, or move the adults out and raise the salinity of the original tank.

    hey there, do you know what type of salt must one buy to increase the salinity?

    a website i found. http://badmanstropicalfish.com/brackish/brackish.html

    Yes, it has been advised that to create the saline envinronment, salt for marine aquariums should be used.

    Mike Noren's website doesn't seem to be working, not sure if it is a problem with the website or my end.

    You can try to go to http://www.archive.org and search for "http://mikes-machine.mine.nu/breeding_yamato.htm". From there, you should be able to read the contents.

    OT a little.
    Since you are already having these shrimps, is it true that they will change colours from time to time?
    Cheers and Regards,

    I'm not always dumb,
    Just most of the time...

    no problem,

    yes bro, they do change colours. Some colours i have seen, pinkish red, black like those in the pictures and transparent. Most of the time the colours are like those in the pictures i posted.

    I saw them in the shop, very small size & many are transparent. Only some have red patches.
    Did you see them changing color in your tank ?
