I recently pulled a female out of my breeding tank because she wasn't as colorful as i would have liked. Im trying to keep only the ones that are the deepest red in the tank. I put her in one of my other tanks thats pretty empty at the moment. I thought maybe she didn't make it because i didnt see her for a week, but i finally saw her today. It was like seeing a diffrent shrimp. She was so red you couldn't see the eggs unless you looked really close. Water paramaters for the two tanks are nearly identicle, temp is withing a degree or two, and they are on the same maintanance schedule. Has anyone else seen the colors change when they are seperated? The diffrence is day and night. She is a stunning deep red now instead of the light/clear colored red she was before.
The only thing diffrent is the new tank has rock substrate instead of bare bottom, and it has a small piece of driftwood.
The opposite happened to me, went into a bare-bottom for 2 weeks nad turned solid red. It's like looking at a different shrimp.
