Shrimp ID -56k-

Hi,
Nice site here, it is great to see a webpage dedicated to this part of the hobby.
I picked up some shrimp from my LFS a while back and just tossed these guys into the wife's guppy-grow out tank. Since then they have been breeding like crazy, but I have no Idea what they are. The LFS had them labeled as "Neocaridina" I kinda laughed since that is pretty vague, no one at the LFS knew anything about shrimp in general and my knowledge was limited but I knew enough that the could be a neocaridina species, perhaps a cross between a couple different neocaridina.
Lets see what you guys think:

size: 3-4cm
breeding: Completely Suppressed: they are miniature versions of the adults
Young are a lot lighter color.

Hi dissident,

the above pic looks very similar to a so called Black Shell shrimp(number 1 algae eater) even better than yamato i heard from an experienced black shell breeder which can be found in some LFS in Singapore except yours have some distinct brown coloration.

Not sure what shrimp this is...btw is it wild caught or home breed?

Just some wild thoughts. If you combine the genes of Cherry + Zebra + black shell shrimp....you might get the form in the pictures. BTW Cherry can cross with black shell shrimp not sure about Zebra.

Or maybe its just another unnamed Neocardina sp. mutation lol

I just got a few of these so called "black shrimps". It seems that they are smaller in size compared to Cheeries. Didn't know they could crossbreed! If not, wouldn't had left them together. The shrimplets are also very tiny, had a hard time spotting them.

The variety of shrimps in singapore just seems to get more and more! :D Any pictures?

[dissident]

Thanks for the thoughts.

They tend to vary in color, mostly the tan and dark brown to black colors on the older shrimp, the adult males have a white stripe down their back. Sometimes they seem to have a touch of green in the younger ones. The very young shrimp are tiny 1-2mm (only spotted one that small once) and clear. They start to get the tan color at 5mm. Then the dark colors after 2 months at about 2cm.

They are great algae eaters and seem to love moss. They hang out on the java and Singapore moss in the tank most of the time.

I started with 10 of them in March and now I can’t even count them all. At least 6 of them have eggs now. I am planning a 55gal shrimp tank that I want to divide into 2 sections. . I may try crossing them with some of my Cherry Reds and see what I get.
One for these guys and the other for Cherry Reds. Unfortunately I can not find any Other shrimp species around here, I would love to get my hands on a dozen ninja shrimp and breed them

I searched around for ‘Black Shell Shrimp’ and couldn’t bring anything up as far as a description or image of these little critters. If anyone knows of a site that has some info on them I would like to read up on them a little and see if that is exactly what I have here.

Or it could be just as simcb said, “Or maybe its just another unnamed Neocardina sp. mutation ”

Could you toss up a few pics? Would be nice to see what you "black shrimps" look like. The ones I have are smaller then my cherry reds but not by much.

To be honest with you, I don't know. The LFS I got them at could only tell me that they were Neocaridina.

Hi Dissident,

I would love so much to post up nice pictures of shrimps, but as of now, my DC is a low end model. Macro mode is as good as none, there goes taking good photos of these small creatures! Would try my best to put up nice photos in future. All I could say now is that my so-called "Black Shimps" looks very much like the ones you had. Mine even show a tinge of blue. Cheers and do update us!

Regards,

Hi,
the description of this shrimp sounds like a another subspecies of Neocaridina denticulata or it could also be Neocaridina palmata. Both species vary a lot in their coloration which is mainly brown, black, grey etc., so the coloration is no way to determine them. A microscope would be more than useful and I guess without a closer observation of the endopod and other parts of the body e.g. the rostrum, it would not be possible to determine the morphology differences and so you cannot say for sure at the moment which species you have. You cannot even say if is a Caridina species or Neocaridina species but there are no obviuous morphology differences of these genuses which you can see with your bare eyes.

Best regards

Robert

I heard from my friend both cherry and this so called black shell shrimps came in from taiwan 4-5 years ago when we didnt even heard of CRS. Black shell shrimps is the fastest higher form breeder I ever encounter, yes even faster than cherry shrimps. Maybe I should get some to try since i got another 2ft empty tank to play around with. :rolleyes:

However only cherry shrimps got popular among singaporean hobbist but the so called "black shell" buying fever slowly melts away i guess most asian hobbist prefer red as red represents luck and black represents not a good color for fengshui. This reminds me of the louhan fever in Singapore 2 year ago and now most of the louhans ended up in reservoirs and rivers destorying our ecosystem :( where did all the mosquito control small fishes go?:shocked:

dissident,

Where are you located in the US? I have never seen the variety of shrimp shown in your pix. Thanx.

I like to hang out in the Milwaukee (WI) area. We seem to be the last to get anything related to this hobby. It took months to just get one of the largest LFS in the area to get Cherry reds. Even then I had to pay $6 a shrimp, and they only got 30 of them, and i havent seen them since. So i was supprised they got these, and like I said they knew nothing about them other then they were shrimp.

[retardo]

You're very lucky to have gotten the so-called Black Shell Shrimp then. I haven't seen anything like that around the SF Bay Area. I think we get a few more varieties around here than you do in Milwaukee, but Cherry Reds were at $6 a pop the last time I was at Octopus' Garden (lfs)... way too rich for my blood. I don't care that much for RCS tho, so I passed. I'd only pay that high an amount for a rarer species, like Crystal Reds.

Hehe.. I have shrimpus collectoritis though... I have 5 different species... one of them unknown.

Thanks to our geographicial location we have access to a large varities of shrimps from neighbouring countries.

OMG $US 6 a piece... same price as crystal red in US? :shocked:

Do you have any picture to show the unknown shrimps species you had?

[retardo]

Unfortunately, I don't have a digicam with a macro lens that would take a good enough picture of the shrimp that you could use to identify it. It for sure is not in the sames species as Caridina/Neocaridina.

And yes, $6 for RCS. They're not exactly that scarce either. CRS, assuming you can even find it, will go for much higher than $6ea, I would imagine.

on aquabid there is a guy selling CRS 6 of them for US$120 :shocked: :shocked: :shocked:
That's US$30 each! And you still have to pay shipping!

I would love to get some CRS and set up a nice breeding tank if I didn't have to spend several hundred bucks to get a good breeding population.

So I'm going to stick with cherry and this 'Black shell' and see what happens.

[dissident]

I did some web hunting on this species whatever exactly it is...

Neocaridina sp. I (redtail shrimp)
http://www.shrimpcrabsandcrayfish.co.uk/Photos/RedtailNeocaridina.jpg

This is the only image I could find on this species but it strongly resembles what the adults look like. However with my shrimp and the one pictured I can't see any red in the tail. Some of the ones i have do have a distinct markings on the sides of them. The stripe down the back is common in all the males I have, and those don't seem to have any other body markings. The Ones with the body markings seem to all be female. Other then that they look identical.

Hey I was going to get you the RCS for $1.95 remember? $6!!! :shocked:

So how are the tigers doing? I lost my babies in my new tank when the eco-complete caused a ph spike to 8.3 ( 7.6 with CO2 )....I'm sooo pissed! They are sending me replacements but what a pain! For $13 a bag I would expect it to have some sort of quality control.....sad! >(
