Pico invert tank

[Jmas4]

I was thinking of having a Pico tank with cool inverts that can't be in a display tank. I was thinking of having zoas, acans, and leathers in the tank. Current stock list is 6 sexy shrimp, 3 pom pom crabs, a pair of bumblebee shrimp, and 1 porcelain crab.
Any issues with the stock? Any advice? How big will the tank need to be? Jbj 3 gallon? Maybe fluval spec 5?

There is a cool invert I just found out about. The emperor shrimp. I think this shrimp aand a sea cucumber host will get along fine.
