I picked up these shrimp today from my LFS. They were labelled "Navy Blue Caridina".

I've been trying to identify what they actually are for a few hours now, but they don't have strong striping like Blue Tigers or Blue Bees should have. Am I just comparing them to much higher grade examples of these species?

Could these just be low grade blue cherry shrimp?

Ask your LFS if they order from SunPet. They have been selling "Navy Blue Shrimp" recently and they don't even have the slightest clue what they really are. Based on the color alone, I would guess blue diamond (which don't breed true), or a darker blue velvet (which should breed true).

Thanks for the suggestions, I'll have to look at them closer.

I did specifically ask the LFS (owner's daughter actually, owner wasn't there) because I was a bit suspicious. She told me they got them from a local breeder here in NJ and that the breeder only gave them the name they had labelled there (Navy Blue Cardinia - yes, it was mis-spelled too ;)). Apparently the breeder sells them multiple species, but this is the first time he's sold them these.

they are not blue diamond. blue diamond are solid not see though. and blue velvet do not have stripes like this.
After looking at them for a bit, I'd have to agree with your assessment wicca, though either of those would have been nice for the price I got them for. :red_mouth

My main concern is my placement for them, since I had been planning on putting them in my cherry breeding tank, but with the species still fuzzy, I'm worried they might be neos :icon_neut

How big are they? try to google blue Caridina babaulti and see if they look the same.
Thanks for the suggestion shrimpo. I had looked at these earlier but had written them off as almost all of the ones I had seen were a single-shade blue without much variation except a little more darkness lower in the body and back of the head.

Though, when you mentioned this, I searched again and looked further down and found this, which, while darker and more solidly colored, seems to be the closest match I've seen yet.


As far as size goes, they seem to be roughly on par with my ~2 month old cherries.

My LFS store was selling "Navy Blues" awhile ago too, and I had them look up the species (genus) which their paperwork said was Neo. (They didn't know, or have any idea why I would care.)

If neo caridina
Maybe Variant of carbon rili or rili

Note: i could be wrong, it is based on local name and grade, seller where i buy these shrimp could be wrong with the name

Above less spot on the middle
Bottom more spot, later cover the entire body

I would be more tempted to agree if the ones I picked up were as thoroughly colored as those pictures. The possible reasons behind their blue-ness (diet/dye/etc) would also lead me to believe it would be more solid.

I shot some more pictures of them today and a number of them have darkened a fair deal since the last pictures when they were acclimating.



This one looks a bit different, though it may just be a better colored female -



And lastly, this one. Which makes it a bit harder to argue against them just being blue cherries with the similarities being so strong.


Either way, I'll definitely be moving them out of the tank they're in now tomorrow and find them a place to be on their own for now.

I also think they are pretty; thanks for the photos.
Keep us updated, especially when they have offspring, to see what the coloration does...

Where in NJ did you get these from?
Aquarium Center in Clementon, my goto place if I need anything besides the basics. Unfortunately, they don't carry that many shrimp, can sell out quick and have a wide range of grade from week to week. Some weeks cherries are almost completely clear, next week they may be high grade sakuras, etc. (which can be nice, since they don't change the price when they're higher grade).


Small update - I got them moved into their own tank yesterday. Somehow, I hadn't noticed that at least 2 of the females were already berried, but it seems they both dropped their eggs after the move :icon_frow. Hopefully they'll berry again soon and I can let you guys know how the offspring turn out!

This is a neo species. I think it's carbon something, can't really remember. They have the light blue like yours and a very dark blue version.
I know as it's pretty common in my country. I bought these before too but they died after I increased my crs population, many more than the blues.
