Help identifying shrimp

Hello All,

To start, I have a decently planted 10G tank. I recently purchased five Amano shrimp from a local fish store (I already had two in the tank and wanted to get them some friends). However, after introducing the five new Amanos to the tank, I've noticed that a few of them don't quite look like the Amanos I've previously purchased/the ones I see online. They're more white than I expected and I've begun to suspect that they may be Snowball shrimp instead of Amanos. Could someone with more experience please help me identify them? I'm fairly new to the hobby (tank is four months old). I have attached pictures. I know that Amano shrimp tend to get larger than Neocaridinia, but at this point that doesn't help me. I've put a ruler in the shots for convenience.

They look like Amano shrimps to me.
Probably one is younger than the other one.
To my knowledge, there isn't any other shrimps that look like Amano except for the red Cherry shrimps that have a few variations and grades.

Okay thank you! I wasn't sure because the larger "Amano" didn't seem to have the characteristic dots along the side and seemed too white. I thought the Snowball shrimp I was talking about was a white variation of the red cherry shrimp. Either way thank you for the clarification!

Actually the photo of the shrimp at the back isn't very clear.
Anyway, just make sure that its not a Ghost shrimp which is also transparent in colour.
