Hi,

Need some help to identify this shrimp. I was under the impression that Blue Pearls are really pale blue in colour but this one is very much darker blue. And it has the yellowish colour on the neck area that does not go away.5258

I'm afraid we'll need a clearer image to be able to tell for sure.
From the profile of the body, my best guess is blue pearl.

Agree with brother Navanod, but not 100% sure, as the image is blurred.

when i bought it, it was not that blue. It was having a slightly stronger shade of blue. It got darker after keeping it. Even when i introduce a male Blue Pearl to it, as i was thinking it was probably female, they ignored each other. Thus, the above question arise. I have another Blue Pearl, and i think it is a female and its colour is really pale blue and quite big in size.

I will have to grab my camera for a better shot later. Took it real fast as this critter is quick to turn. perhaps both of them. will update this post with better pictures. :D

I keep a few types of shrimps or rather variations. still trying to differentiate which are males & which are females.

Its an interesting challenge. Am still learning about it.:p

Learning new things is what made hobbies fun. I too am still learning to tell male and female aura blues apart

Wow! Just by looking at the egg saddle, can tell the type of shrimps?
Cool!lol
If you say Egg Saddle, means its a female. How long do they keep their saddle, because this one kept it like for a very long time already. say 4months, but never got berried.

Time does not matter, it is the shrimps need to mate. For shrimps to mate, the female has to molt first. And of course you need to have a male pearl blue (this one maybe just cherry blue, but named pearl blue in Singapore).

to me that the initial picture of a female, not to remove the yellow stain is that sometimes in winter tend to retain future eggs longer than normal, but also diffuse this picture, you see the pleodos very wide for a male very nice photo that sengunda jellis, have to be a teacher to take that photo, thanks for sharing

Hi,

Please, help to identify this shrimps. Are they blue perls too?
I purchased these together as Neocaridina var Blue.

Oh? They appear to be ye olde generic "blue shrimp" sold at many places some years ago. They do not remain blue and do not breed true hence they are neither blue pearl nor aura blue.

And what will be their breed? Colourless? Are they crossed whith shrimps "neocaridina heteropoda"?

They can be green, blue, black or brown or mostly a combination mix. I'm still not sure what exactly their lineage is since I had not tried to breed them

The 'blue' or 'blueberry neocaridina' is one or more type of shrimp that gets sold all over the place as a 'blue neo' but they do not breed blue or always stay blue.

They aren't even all the same species all of the time from what I gather so it is pretty unpredictable what they actually are.

Yes, the "wild cherries", "neon green cherries", "blue neo" and "malayan" shrimps sold in Singapore are such low value shrimps that no shops would be willing to waste time defining and separating them by actual species.
It's a mixed bag of surprises half the time.

Yes, my shrimps have been sent from Singapore with "wild cherries", "neon green cherries", and "malayan" shrimps.
