This shrimp finally moved to where I could take a photo. It's unique in my tank. It is dark brown with a wide yellow stripe down its back.

Sorry about the quality of the photo; my camera doesn't deal well taking photos through 10 mm glass.

That's a special iteration.

My shrimp haven't got the wide stripe look yet, but I think Im not far off

Is it a female?

 

[Essjay]

I'm not sure. When I see it, it's usually on a leaf at the back of the tank where it's too far away to see clearly. When I took the photo I was too busy trying to get a decent shot to look at the shrimp properly

 

[MaloK]

At it's size it pretty easy to have a good idea. If it has a Straight abdomen it's a male and Rounded is a female. Also the length of antenna is an indicator. the major difference is the second pleuron (2).

Is it a female?

I've just been doing a water change and the brown shrimp with the yellow stripe swam right past the front of the tank so I was able to have a good look.

Definitely female.

Some photos of the yellow shrimps I bought yesterday @seangee

Every single one of those yellow shrimps is female. It's also unusual to buy a group of neos and have not one female carrying eggs. This makes me wonder - did the breeder/shop separate males from females to stop the customer breeding their own?
I phoned another shop this afternoon to ask, and they do have yellow neos in stock. I wonder if they'll have any males?

A few questions about shrimp:
- But are there only Japonica shrimp, a medium-sized, non-aggressive shrimp that can be kept with Bettas? Are there only wild, neutral-colored Japonica shrimp?
- I saw a lot of small shrimp in a store with half red and half white bodies. Are they neocaridines?
I love shrimp, but I'd like them to be more visible in terms of size and color.

The small shrimp could have been juveniles.

There are two types of red and white shrimps.
Neocaridina davidi, variety red rili. These will stay small, the same size as the solid red variety.
Crystal red shrimps, Caridina cantonensis or C. logemanni - different websites use different names. These grow to about 3 cm but need soft water and pH below 7.

so they could go well with a betta instead of the Japonica?

 

[Essjay]

If the betta allows it. Some bettas will not tolerate any creature in the same tank.
Crystal red shrimps are less tolerant of water conditions than Neocaridinas. They must have soft acidic water.

I bought 2 more yellow shrimps yesterday, I took a magnifying glass with me and I think they were both males.
And I bought two deep blue shrimps for my main tank to add a bit more genetic diversity to the mixed colour group in there.

I also acquired a juvenile endler as they were in the same tank as the yellow shrimp and one was obviously netted with one of the shrimps. She's gone into the main tank.
