Mystery shrimp

[Sputnik]

Hi all

I got this shrimp with my order of amanos after one od my mature females attempted a jailbreak, leaving the other 2 heartbroken ( RIP Big Momma, sorry I did not find you in time). It is much bigger than my biggest neo but much smaller than my amanos, so I moved it into my blue dream neo tank about a month ago, and its doing well ( pH 7.4, ammonia 0, nitrite 0, nitrates 0-5, temp 75 Fahrenheit).
I only keep amano and gold nebula caridina species, but it doesn't look like any caridina I have seen, and looks too big to be a neo at almost 2 inches. Any ideas? Is it a low grade Taiwan bee, maybe?

richie.p is very good on this topic, maybe he can help.

Thanks!

I believe it's a neocaradina which morph is changing to rilli not that much different to the one in the background of the first picture saying that 2"is a monster and the rostrum looks big as well, let's have some more pictures with a bit more light and possible close to one of yours as comparison

I’ll try for more photos but this one is pretty reclusive so it may be awhile- good thing I’m trapped at home! I appeciate the input! Thanks Ritchie.P!

I'm as interested as you I think the best I've done is 1½" maybe a tad over it was like a pit pony. Yours looks female from this side I don't know what you think it'll be interesting to see some off spring

I have quite a few big females in that tank and she is the longest -she is not quite two inches though- best guess is about 1.75 or so. And her shape is just different, though I can’t say exactly why. Here are a few pics with a second light over the tank. No adults nearby but on one pic you can see a juvenile on the cholla if you squint!

Here is a photo taken about 2 weeks ago of one of my bigger blue dreams -it has a reasonably good viewp of the rostrum for comparison.

It kind of looks like a carbon rili shrimp

Yes it does, but its huge, and has a really long rostrum (which I guess some davidi do), and is much more secretive than the blue dreams. This is only the second time in a month that I could get a good look at it. Maybe its a genetic outlier rather than a caridina, but I am just guessing at this point!

Looks like a regular neo, i've had some really large females before (almost twice the size of an average neo), that didn't quite look the same as the smaller cherries.

Thanks!! Guess she is in the gene pool then!
