Cherry Shrimp Experiment

This is my little Cherry shrimp experiment!!

Primary objective is to test these Cherry shrimps' intelligence by allowing them to find the entrance to this crystal box filled with food inside!!

This is not an easy task for animals with stupid do the obvious!

The shrimps are apparently pretty smart!

Anyone Can Help Identify This Shrimp?

My red cherry shrimps, Sakura shrimps are living happily with another types of shrimps for some time and I don't even know what to call these shrimps.

They are spotted to have black-white stripes with grey black overall with possible similarities of those from Sulawesi Shrimps..but I am not very sure.

Anyone can identify them?
