green shrimp

[skewlboy]

So in a batch of "tiger shrimp" from a little place in Tucson about 1 month ago I also received some very small babies. They were the only things to survive the 2 hour overnight mail from there (mostly belly up shrimp on arrival). Anyway, 1 month later and it comes true that whatever they sent that was mostly pink and decaying must not have been tigers since the babies in the bag are very green, small, and much resemble the green or midget green shrimp. Out of the 10 very tiny shrimp I now have 4 15mm juveniles.

My question to all of you is do you know what shrimp I can keep in this tank and not worry about hybrids? Spec page says green shrimp are a caridina but I've also seen other places that say they might cross w/ cherry shrimp (neos).

Whats up?

The other places are wrong. Caridina can't interbreed with Neocaridina.

[skewlboy]

does anyone else raise these and have they had success keeping to breeding age? If so, what is your tank setup?

[badflash]

You can keep these with Red Cherry shrimp with no issues. I do.

Check the shrimp varieties page for shrimp that share the same water parameters but have a different genus. caridinia and Neocaridina will not interbreed.

caridinia and Neocaridina will not interbreed.

Yes, and most caridina won't interbreed with other caridina either. Caridina spp. will almost certainly go through revisions in the future as there are way too many very different shrimp classified as Caridina. That includes both shrimp that produce saltwater larvae (like Caridina gracilirostris, Caridina japonica) and shrimp that produce miniature young (like the green shrimp, tiger shrimp etc.) in freshwater.

But even most shrimp that have similar reproductive cycles, such as tiger shrimp and green shrimp, and belong to Caridina cannot interbreed. For shrimp to be able to interbreed they need to be very closely related..in other words, they need to belong to the same "species complex." Tiger shrimp and bee shrimp can interbreed because they belong to the same "species complex" (the so called "C. serrata" group). Most Neocaridina can interbreed because they are all very closely related.

So, bottom line is, just because two species belong to the same genus, it does not mean that they can interbreed.

Any possibility you could update the Shrimp Varieties page to say what species not to keep a certain shrimp with? I think you do that with a few already.

I also think that would be very useful to anyone thinking about keeping more than one kind of shrimp.

I have done that with all species as much as experience allowed me to. The rest is just common sense. For example, you can be sure that a shrimp with saltwater larvae cannot hybridize with shrimp that don't produce those larvae. Also, generally, shrimp from India won't ever hybridize with shrimp from China...at least I am not aware of any so far (and neither is anyone else). If any additional information becomes available I will update this site accordingly.
