Small Tank For Shrimp Colony

What’s the smallest tank I could use for a shrimp colony? Other than brine shrimp I would like to have maybe 2 types of shrimps with different colorations that can’t interbreed.
My little idea in my head is a small tank on my desk like a betta tank (1-3 gal) but if that’s too small I won’t do it, I don’t want to be causing unnecessary stress. Any suggestions on tank size and types of shrimp? This won’t be for a couple months

 

You can do as small as 1 gallon, but I'd only recommend one species for such a small tank.

What about a 3 gal? If I only do one species that’s fine just curious. And what species are the best

3 gallons is even better, I think in that you would do well with some neocaridinas of one color with 1-2 amanos.

Thanks- will those species interbreed to make brown shrimp or will the keep their color?

Neocaridina, aka cherry shrimp varieties interbreed, but amanos (different from ghost shrimp) are a completely different species and need saltwater to reproduce

Oh so the Amani’s wouldn’t reproduce themselves? How would I start a colony then?

You wouldn't be able to with amanos, and they get quite a bit larger than cherry shrimp so you wouldn't want that many in a 3 gallon anyways. People mostly drop a few in for hair algae control. The cherry shrimp will reproduce if in decent conditions
