At last, eggs!

badflash, do you mean other colors or patterns? This sounds very interesting

Yes, there is a post on these elsewhere.
viewtopic.php?t=1997

I got a bad batch oof shrimp that turned out not be be red- they were hybrid wild browns and they ruined my cherry population while I sorted things out. I pulled all the adults that I could tell were reds, and ended up with a tank of mutts. Some ended up colorless, others sort of a yellow, and one group I thought were greens. The greens turned out to be color changers and took on what ever color they were on.

Unfortunately, these were all lost last Thanksgiving when the water company switched to Chloramine without notice.

Yes, I remember the post where you had pictures of green shrimp that were hard to pick out of the java moss. Thanks for the reminder. I think it would be too much work for me to give it a try at this point

Thanks.

The reds and browns are already mixed. These are the zhangjiajiensis from Germany that were sent along with some crayfish. The berried female doesn't have as much red color as the two others that have now produced babies. Although it's difficult to see in the pic, the red color doesn't extend all the way down the sides, and the back isn't solid color either. The other two are red all over, one is a darker shade than the other.

There is one male somewhat similar in markings to this female, but the red color is more striped among the transparent areas. Aside from the color resemblance to cherry shrimo, these are clearly larger shrimp, and the females carry aa larger number of eggs. I've noticed quite a size difference in the young as well. Though less than a week old, the first ones are almost twice the size of the new hatchlings.

Now, it's just a matter of time and patience to see what color/s the new young will grow up to be.

More eggs = more babies

! Congratulations. Who knows, you might have a genetically enhanced shrimp

If you have room, set up a 10 gallon tank and pull the ones that are clearly red out. Males that are mostly clear with red stripes are red males. Red ones seem to breed true. When you see red ones after that, just pull them out & add them to the red tank. The other tank will provide suprizes.

I know the berried female mated with a red male, because it's the only male on that side of the divider. The divider was placed in the tank to isolate the berried crayfish, and several of the shrimp were incidentally separated as well. I believe the other two shrimp were already carrying eggs, but the female in the pic hasn't been near a brown male for a couple weeks.

The question still remains though, is this a natural color form of zhangjiajiensis, or is the color a result of crossbreeding somewhere in their genetic past?

What would these be called when the red is established?
Jumbo Pseudo-Cherry Shrimp?

Bloody Snowballs?

Sounds like you're cursing at the Snowballs

Anyways, sounds like you are having a great success with breeding so far, so congratulations!

I vote for Jumbo Pseudo-Cherry Shrimp, but this would be a common name as you know how long it would take for a scientific name to be agreed on

Not me, but anyone who mixed these with actual snowballs might...

It would be an interesting combo, but I doubt the young ones would be white.

I have seen wild-color zhanjiajiensis being advertised as good for diverifying the gene pool of snowball shrimp stock. What would be the result of crossing red shrimp with white? (Genetics wasn't one of the subjects I ever studied.

)

hehe

Don't worry, I am not good with genetics either

Whatever you do, just don't distribute these as "N. zhangjiajiensis" as the origin of your mutt animals is obscure and crossbreeding having occured with the red cherries very likely. Just call them hybrid Neocaridina sp. of unknown origin "sold to me as N. zhangjiajiensis, although clearly not N. zhanjijiensis."

By the way...the ID of N. zhangjiajiensis itself is very suspect as this species has been originally described by using only one male specimen I believe. We might all be just dealing with a local form of N. palmata or even another Neocaridina sp..
