Ok I have had this freshwater shrimp for a while. He came in with my zebras and tigers a while ago . He is much more blue than i have ever seen one so i am wondering if he is a hybrid with a pale blue taiwon or anything

Well no i didnt as i had never seen them offered.

I guess trying to breed a blue with a regular is going to diminish its col0ring??

Hi Marc,

Neocaridina (e.g. "Taiwan (pale) blue") and Caridina (e.g. Tiger Shrimp) cannot interbreed. Plus...the so called Taiwan Pale Blue is not even blue under normal lighting. Some shrimp turn blueish when there isn't enough lighting but turn back to their normal, non-blue color in a lighted aquarium.

Yes, once in a while there are blue Tiger Shrimp in batches of normal Tiger Shrimp. The question is if they are naturally blue or just happened to be eating some of the food coloring that some of the so called "blue shrimp" that you see imported sometimes were eating. Those "blue shrimp" never stay blue for long and if they do (I had those too) their offspring are never blue but normal "wild type" color again.

Take care,
Mustafa

Hey Thanks for the info I have had the shrimp for 2 months approx. I was told on another forum one of the shrimp a local guy picked up has the same blue so hopefully we can get a mating pair

Not too expert on this, but kind of looks like yours is a female based on the deep body.

I have some of these blue specimens as well, and they've maintained their color for as long as I've had them (several months now). If there's a dietary coloring that is occurring, I am certainly not the one giving it to them. They survive on java moss and algae pellets. I have too many tigers in the same tank, so it would be hard for me to separate them out and say whether or not the blue can be bred. That would involve a far greater space than I have.

wwwFish-ForumS.com, I also have tiger shrimps. Some are bluish like yours and others are rather blond.

But your shrimp is not what is called blue tiger shrimp. The blue tiger shrimps have orange eyes, not black eyes.

What are the different names then dependingon the eye color?
