Guess what shrimp

Guess what shrimps these are. They are tiny shrimps of less then 2cm big and the size of eggs are like what neocaridina have.

There are many shrimps out there and this may not be a popular choice as a aquarium shrimp.

These two are caught from same location and they are identify to be of the same species

my guess

no. 1= amano
no. 2=cherry red

what do i win?

Guessing would be useless here. None of them are Caridina japonica, that's for sure. The first pic looks like a male N. denticulata, but it could be a male "anything." The second one has brown eggs, which N. denticulata usually don't have.

In other words, it's tough to tell from the pictures. If you could send me a group of these animals, I can try to identify them.

Where exactly did you catch them in south east asia? There are so many shrimp species there, you should count yourself lucky that you live there....hehe

Take care,
Mustafa

Indeed it is hard to tell. Initially i thought it was a neocaridina species, however looking at the close-up of the rostrum, some expert identify it as Macrobrachium lanchesteri

Trust me, it's definitely *not* a Macrobrachium. You don't even have to look at the rostrum for that.

Tell that "expert" that calling this species anything else but "Caridina" (or similar Atyid shrimp species such as Neocaridina...) is utter nonsense. Anyone with even half a clue about shrimp could tell you that. Macrobrachium shrimp are Palaemonid shrimp and the differences between Atyid shrimp and Palaemonid shrimp are apparent right away. The question is what kind of Atyid (in this case probably Caridina) this shrimp is. So..for now it will just have to be called "Caridina sp.".

Hope this helps.

Ben, you've to stop using different nicks in different places otherwise even I cannot identify you! must less identify the shrimps.

For clarification, the "expert" is indeed an expert, but in catfishes, not shrimps. so…

this shrimp is obtained from the forest streams of Singapore which apparently have not yet been invaded by foreign species, in that all the fishes observed there are native. presumably hence this shrimp is native to Singapore.

I will post some other pics later. size at maturity is 13mm by the way.

Hello Heng Wah!

I did not want to insult the "expert" (whoever it is). I just wanted to point out that the information is wrong. That's all.

This shrimp could very well be a native shrimp, in which case it would be great to breed them and send some of them over, so I can share in the joy of keeping native "Singapore Shrimp."

In any case...there are lots of shrimp species in that region in general. Potentially any shrimp you discover in some far away creek in the forest could be a new species. That's what's so exciting about this hobby. The vast majority of the shrimp species have probably not even been discovered yet!

Mustafa
PS: Yes, definitely post some pore pictures. If you have other shrimp species, post pictures of those guys too. I am very interested to see what kind of shrimp species live in your "neighborhood."

that's good cos he is living in the US presently and can come to NY and populate your shrimp tanks with nasty catfishes

*just kidding*

breeding appears to be quite effortless! we'll try to get up enough numbers and then see how we might send you some.

some of you may know that Singapore is a minuscule, highly urbanised island. nevertheless biodiversity is mind boggling even in the little patch of forest we managed to preserve. two endemic species of freshwater crabs were discovered in that forest in the last 10 years.

but before I show you some shrimp pics I would like to show you the hazards of fishing there! at the risk of being accused of posting non-shrimp pics

MINDEF = Ministry of Defense, and yes they are supposed to shoot people

and one Singapore Dollar is roughly equal to US$0.70 so go figure.

and since we are friendly people, here's me (on the right) and "healtheworld".

and here's the little lady herself… (apologies for the big pic but I wanted to show you her beautiful body… and eggs)

BTW this same forest yielded the tiny fan shrimp Caridina temasek which until not long ago was thought to be endemic. They have since been collected from the Malaysian state of Johore which is just north of Singapore (separated by a narrow straits).

ps: Temasek is the old name for 13th century Singapore.

Hi Heng Wah,

You can really take fantastic photographs. Would you mind sharing your secrets?

no secrets, just a good close-up filter (as I'm using a digicam, or a good macro lens if you use DSLR), lots of flash power, tonnes of patience and fortitude, and quite a bit of luck.

oh, lots of practice helps too.

--Haha...oh I better watch what I say next time then...

. That's a serious threat!

--Great! I could tell from the large eggs that they should breed just like all the other algae eating shrimp whose larvae do not need brackish water. If you actually do get large numbers of offspring, you can send them through UPS, FEDEX or any other "next day delivery" service. Of course I would pay for shipping and the price of the shrimp.

some of you may know that Singapore is a minuscule, highly urbanised island. nevertheless biodiversity is mind boggling even in the little patch of forest we managed to preserve. two endemic species of freshwater crabs were discovered in that forest in the last 10 years.

--Yes, Singapore is tiny but it's in the middle of one of the most diverse regions of the planet (south east asia). There are many more discoveries waiting to be made.

--I knew that Singapore was highly regulated and has very strict laws, so this does not surprise me.

--Haha..don't worry about getting shot. The most they will do is beat you with a stick publicly for your "offenses"....

--You look like very nice guys.

Maybe I can come and visit you guys some day and we'll go catch some fish and shrimp together. Your face looks very familiar...do you have a website? I might have seen it before.

Take care,

well first we got to get them to make more whoopies

actually they are lovely shrimps, nice speckly shell with pretty red eyes. I'm trying to get a positive ID by dunking some in alcohol and sending them to the shrimpies at NUS (National University of Singapore).

do let us know if you head this way. oh and bring US$7,000 in hard cash (refer to above signs)

we're putting up a virtual freshwater fish museum at http://www.hexazona.com which is at the moment under construction (excuses for a lousy site

) it is meant to provide positive visual ID for freshwater fishes, although I don't think our faces are in there.

you can google my name and get some surprises
