Help identifying shrimps

[Pedro Rosa]

Hi there, I need some help from the shrimp specialists ,

I had some Amanos and Neocaridina heterpoda/red cherries on a aquarium but some of the so called Amanos i had weren't, maybe, Amanos, because i think that 3 or 4 are newborn on the aquarium (what is not possible/easy).

Thank you very much.

Shrimp 1 - about 3 cms

Shrimp nº 2 - about 2,5 cm

Shrimp nº3 - about 2 cm

Shrimp nº4 - about 2 cm

Pedro.

I think shrimps 1 & 2 are Amano Shrimp. The two middle shrimp are just Neocaridina with natural colouring I think.

For the size of each one i also think that way, but can i ask you why is that your opinion?
