I saw a post for blue glass shrimp on a certain online fish selling site and wondered if anyone else had seen them or even purchased them? I was pretty certain the only time glass shrimp go red or blue is stress induced. And when I looked at the supplied photo the shrimp appears white bodied under the blue. Is my suspicion on the health of the shrimp correct?
You can cross breed them with any other Palaemonetes species.
But it's not worth it. They are generally clear bodied and the result will be the same, a clear bodied shrimp.
Trying to cross breed them with Caridina or Neocaridina, will result in rather bland looking shrimp as well.
So not much reward for the effort.
