saddled Amano shrimp
When I did I saw a few Amanos and other shrimp images as well and they were very similar, so I think it is saddled, and a female from your pic, it is kind of hard for me to see it clearly.
After a few days it will just disappear and you will begin after a week probably to be able to notice the eggs - called berried shrimp if they were successfully fertilized.
On a disappointing note, they generally can not survive their birth, larval stage with out brackish water and then developing when needing fresh water. Some people have experienced living "fry" - what the baby shrimp are called.
So although VERY unusual unless they were Grass shrimp which are a large number varieties from different parts of the world, basically clearish dwarf shrimp from the Neocaridina family.
The Amanos are interesting and they can be tinted a blue, or green or even seen some which seemed a bit yellow. Sometimes it is their genetics, but also foods can cause a little coloring. And you will see the foods color in the digestive tract.
Male Amanos have little dots at their lower area of the abdomen. Females may have dots towards the top and dashes or elongated dots at the lower side. If I remember correctly...????
