CRS dropped eggs

Hi Max,

Welcome to the forum! N. denticulata sinensis in general are very prolific and can outbreed other species easily. That is the reason you are seeing more of them. As to why you are seeing more "Red Cherries" than the wild type (I don't like "Taiwan Blue" since there is not even a hint of blue in them) is because you probably started out with more Red Cherries. However, I can guarantee you that won't have any red shrimp left after a couple of generations. The red is recessive and will disappear if you keep those two color varieties in the same tank.

By the way...Taiwan has tons of very interesting shrimp that never make it to the US. Maybe you can bring some back with you the next time you go visit family?

Btw, this is Max from San Diego. I am orginally from Taiwan, came to States for graduate school 4 years ago and now working in the pharmaceutical industry.
I have cherry red, India green and Taiwan blue(which we called 'black shell shrimp' back in Taiwan) in my 20G tank with 30+- species of plants, some pencil fish and some tiny corydoras/oto. cats.
My plants(even some Tonina) are doing ok at PH=7+, so I never bother to adjust PH. Although most people recommand PH around 6.8 for planted tanks.
Very nice to meet you folks here, it's always nice to chat with other hobbysts.

Mustafa,
Any tip on how to carry live shrimps through flight? I thought about it before, but was worried that it's easy to be found by the custom or flight security. And what species of shrimps in Taiwan are you specially interested in?

I actually have another small tank where I only keep cherry red there, so I won't lose the red type of N. denticulata sinensis. Can you recommand any article that talks about the genetics of shrimp shell color?

Thanks.

If CRS lower your PH

Well here they are

PH - 7.4
NH3 - 0
PO4 - 0.25 (I am hoping that it is not going through a mini-cycle )
NO3 - 5
NO2 - 0
KH - 50
GH - 80
74 deg F / 23 deg C

Cheers

Hi Max,

*Any shrimp* you can possibly catch in Taiwan would be great. Taiwan also has a large variety of freshwater crabs that stay small and produce miniature young (as opposed to the tiny larvae salt/brackish water crabs release into the sea). All very interesting animals.

Here is a website about Taiwanese freshwater crabs:

I guess you could put them into a styrofoam box and take them as a "carry on." That's what the German shrimp hobbyist do every time they catch shrimp on vacation abroad and bring them home. Alternatively, you could just put them into your luggage and check them in. The worst thing that could happen is that they take away the shrimp I guess.

You might also want to check with the Taiwanese authorities, to see what their requirements for personal export are if you want to prevent the possibility of losing your animals.

Another possibility is that you FedEx the shrimp to your own address in the US for next day delivery.

As to the article...I have not come across an article that discusses shrimp coloration in detail. Most journal articles are about their anatomy and identification.

Take care,
Mustafa

That's how I 'import' my plants back from Taiwan. Hmmm...I will try shrimps/crabs next time. Hope some small bottles of water are not too catchy for those security people.

Thanks.

Don't use bottles. Use Kordon "breather/breathing" bags. That way they will last for days if need be...also put some plant material in with them so they can hold on to it.

The crabs actually do not even need to be in water. You can put them in sealable plastic boxes with dripping wet paper towel or cotton-like material. Only put one per container since they tend to eat each other up in transit.

Then, of course,...send some of these animals right over to me so I can breed them and make them available more commonly in the future.

Sure. I will try to bring back as many species as I can, just hope I can find some time to go back next year.
How many tanks do you have? It must take a lot of space to do the species collecting and breeding.
