Hey,
I just got 4 of your Orange Shrimp (can't find which stock thread I saw them listed in...) and I've found out a bit about them.
Upon taking a close-up look, and consulting with some FW Invert forums, I believe they are known as Mandarin Orange Shrimp (Caridina propinqua).

They require a saltwater phase in their egg development cycle, and go through a benthic stage, so they're more like Amano Shrimp, which, to my knowledge, are not widely bred by hobbyists.
Still though, they are reported to be a very good scavenger and algae eater, and gosh darn they're pretty!
But... so much for thinking to try and breed them.
