Yes

Yes

No. I am assuming biene is a caridina species.

hello, can you tell me if it is possible to keep:

-white pearl and biene

Yes

In general most caridina sp. and caridina sp. is a no. Neocaridina and neocaridina is a no. Caridina sp. and neocaridina is a yes.

Read over the water parameters in the shrimp variiety pages for these species. The pH ranges need to be compatible and are not. You need to be carefull about mixing alkaline and acid loving shrimp.

[Matteino^82]

yes i understand about the water parameters..in the tank with white pearl i have tap water (approx pH 7.2-7.5 medium hardness)...
so i think that biene are not able to live correctly in this water...

[zwergkrebszuechter]

Sure they can. I breed all of my shrimp in hard and slightly alcaline water. (tap water without changing anything)
There were some starting difficulties with crs and bumblebee etc, but the generations born in my tanks do very well.

Well, That is interesting.

Your post is the first to mention, success in breeding, Soft water Shrimp in hard water.

Has the life span of the Adults, been shortened ?

Do the Adult Females carry the same amount of eggs ?

All of the serious breeders of crystal red and bee shrimp (mostly in japan) breed their animals in acidic water, usually in the 6.0 to 6.5 range. In their natural habitats their wild cousins live in even more acidic waters, usually at ph levels under 6. I myself noticed that they feel much better and have a higher survival rate for their young in acidic water. It's probably not a good idea to recommend to beginners that they should start keeping and breeding their CRS in alkaline water. Many people have already lost lots of CRS partly because they threw them in alkaline water with their red cherry shrimp and hoped for the best. Their red cherry shrimp continue doing great, but the CRS die one by one. My shrimp become less and less active the more I let my ph get closer to the 7 mark. Then some start dying...slowly but one by one. When I decrease the ph again, they start becoming active and the dying stops.

So, of course, they are exceptions to any rule, but have you ever tried breeding your shrimp in acidic water to see if the rate of survival for your young is much higher? I bet it is.

On the other hand, if you really have a strain of CRS that is used to alkaline water, then that would be great. But before we actually decide that's the case, it would be helpful to know how you test your water and what your water parameters are. Do you use an electronic ph meter? If so, what exactly is your ph? What's the conductivity of your water?
