Hmmm, Red Tiger? What in the heck is that?

That "red tiger" shrimp on the picture is sick and dying. Shrimp get all "milky" colored and white and even change color (for example black does become reddish...) when they are about to die.

It would be interesting, though, to see a real red tiger. Other than that...he has some interesting shrimp on there, although he must have made up some scientific names out of thin air. For example...there is no "Caridina huananensis". However, there is a Caridina hainanensis.

Mustafa, thank God we have you
I didn't know that - it's sad but interesting information.

Names of shrimp on the market make me sick sometimes, for example "Burman Shrimp". It's supposed to be a freshwater shrimp. Didn't find any info

Hello,

One of my friends pointed this thread to me.

Well, there is Caridina huananensis, a new species described by Prof Liang Xiangqiu this year. Well, can always try following book, it's in Chinese though.

Fauna Sinica Invertebrata Vol.36 : Crustacea Decapoda Atyidae
Liang Xiangqiu, 2004

I have the book but it's useless without proper equipment and well trained dissecting skill(I doubt how many hobbyists do). So I am giving away my copy.

I made the mistake for the name and I didn't correct it in time. There are a number of "bee shrimps" in China. Some look same(at least to normal people like me) but they are different species. If I want my shrimp's scientific name to match with my pictures, I got to send the specimens to Prof Liang everytime after I take pictures. It's his interest anyway but too troublesome for me.

This shrimp in the picture is the C.huananensis. This friend of mine is the contributor of specimen when it's first being described. By the way, the specimens come from fish market in Shanghai. Shrimps come from Guangdong province.

Please ignore the file name, it's for my own convenience and there are mistakes(in the fish gallery) here and there.

I killed a number of tiger shrimps but none showed that kind of red color and lived for weeks as it did.

Cheers,

Hello Zhou Hang!

Welcome to the forum! I am glad that you can comment on some of your pictures. See below for some answers and further questions.

What's the title of the article? Fauna Sinica is a scientific Journal with many articles in it. You would have to give me the title of the article. I can find the article if you give me title.

There are a number of "bee shrimps" in China.

This is problem with common names. "bee shrimp" was just made up by someone and people are using it now. What you are referring to are probably species that belong to the Caridina serrata species complex, to which also Caridina cantonensis belongs. Also, are you sure that the "Tiger Shrimp" is Caridina cantonensis? Some people at Hong Kong University seem to think differently:

http://www.hku.hk/ecology/porcupine/por ... shrimp.htm

Scroll down all the way and you will see what *they* think Caridina contonensis looks like.

Some look same(at least to normal people like me) but they are different species.

Yes, different shrimp species can look quite similar. But the trained eye can usually tell the difference.

If I want my shrimp's scientific name to match with my pictures, I got to send the specimens to Prof Liang everytime after I take pictures. It's his interest anyway but too troublesome for me.

Who is Prof. Liang? Does he specialize in crustacean decapods? I am just asking because he might be of help in the future for identification purposes. Does he live in Malaysia or China?

This website is down...not just the link but the whole aquarecord.com website is not working.

This shrimp in the picture is the C.huananensis. This friend of mine is the contributor of specimen when it's first being described. By the way, the specimens come from fish market in Shanghai. Shrimps come from Guangdong province.

Are you saying that they sold as food shrimp there? Were they still alive when they were sold?

Please ignore the file name, it's for my own convenience and there are mistakes(in the fish gallery) here and there.

No problem. It's no big deal.

I killed a number of tiger shrimps but none showed that kind of red color and lived for weeks as it did.

When I say "it's a dying shrimp" does not mean that they are going to die right away. They can live for weeks before dying actually. I did have some Tiger Shrimp that turned reddish before they died (imported animals that were "predamaged" when they arrived here). However, if you think that you found a population of Red Tiger Shrimp, that would be great. Did you catch all of those shrimp on your website yourself? Was that Red Tiger shrimp alone or were there more?

By the way, this shrimp: http://img.photobucket.com/albums/v470/ ... nensis.jpg

and this shrimp: http://img.photobucket.com/albums/v470/ ... ed_bee.jpg

are most likely the same species. They are called Bumblebee shrimp here. I have never seen a red color form, though. Did that red shrimp stay red for a long time or did it change its colors? Again, did you catch both shrimp from the wild or did you buy them in the store? If you caught them, were there more red shrimp where you found the one in the photo?

Take care,
Mustafa
PS: By the way, I would love to come to Sout East Asia and catch some shrimp and fish with you some day. I love collecting animals myself, although my purpose is more to breed them and spread them in the hobby here in the US.

Zhou Hang is a respectable serious hobbylist who has travelled around Asia collecting fish/shrimp speciment and took good pictures of them for record.
It is good to have him to work with experts or prof to sort out the common name given by the local people with scientific name.

Thus it is best not to give him too much doubts as himself is still trying to get things right

I think I was misunderstood here. I am not trying to be antagonistic towards Zhou Hang. I actually appreciate that he is attempting to discover the scientific names of these wonderful animals. I, and some friends of mine in Europe, are also trying to do the same thing. That's why it would be a great thing to work together. But Zhou Hang has not even replied to this post, so I asume he also misinterpreted my message.

I really want him and others like him from Asia to participate here and share their experiences and knowledge. My questions above were genuine in an attempt to clarify things.

I hope this clarifies some misconceptions and confusion.

Take care,
Mustafa

i've had shrimp die on me before, and you are correct that they do turn a reddish color. i mistakenly bought an amano that was on it's way to algae heaven because i tho't perhaps it was a different variation. it died two days later. if i may tho, is it possible for a dying shrimp to exhibit that strong a red? my experience is that it's more pinkish than red... but then again, i only have amanos and tiger shrimp, and even then, it's only been a few months. so please excuse my ignorance, if that is indeed the case. =)

The intensity of the red before dying can differ. Some animals don't display any red at all actually, whereas other turn either pinkish or reddish or just lose all their colors or change to some other "weird" abnormal color. It differs from species to species, too.

Mustafa

Oh, if only I could have read Mustafa's mail a day earlier. I bought four tiger shrimps this afternoon and one of them got red stripes. It's the only red one in the tank where there were about a hundred tigers. I thought I got something extraordinary And I thought one of its parents was Cherry and one Tiger.

Not possible.

Now a pair of Cherry and a pair of Tiger are in the same tank. Then I don't need to worry about 'cross-breed'. In fact, my knowledge on shrimps is limited. I've tried to find a book on shrimps but unfortunately there is none here in my country. Fortunately, this website is extremely informative.

No, you don't need to worry about the Red Cherry and the Tiger Shrimp crossbreeding. Also, there is no usable hobby-reference about shrimp anywhere in the world, not just in Hong Kong. I get all my information from experience, exchange and reference in scientific journals. But even science does not even know about most shrimp species (i.e. most have not ben been scientifically described).

Mustafa

Thanks a lot Mustafa !

Your website is really great. I bought a bag of ten tiger shrimps last month but they died one by one. I was eager to find out what I should do before the whole batch would pass away. We have a 'fish street' here in Hong Kong but none of them have any reference books on shrimps. Then I tried to look for information from local websites in Chinese. I'm so lucky that I finally come across your website, which is the best one. Now I have two survivors (Tiger). They look healthy and happy.

I remember you mentioned you would like to get some wild shrimps. I've got this piece of information from a Hong Kong website :

Get off at May King Garden in Tsing Yi
Straight ahead to Tsing Yi Technology
10 minutes walk
Then see the second brook
Hundreds of tiny shrimps are in there

Well, that sounds like a treasure map.
