Hi all,

I suspect that population density plays a part in shrimp coloration. Perhaps a shrimp with fewer neighbors has less stress and colors up better? My main CRS tank is quite crowded now (hundreds of CRS in a 25 gal cube tank) and very few of the shrimp look as good as the shrimp in a different tank which is sparsely populated (12 shrimp in a 20 long) and consists of shrimp originally from the main tank.

To add what I had said in the first post, here is a current pic of a SSS I pulled from my main tank a few months ago. At the time his white coloration was really poor, like cull tank poor. I suspect that stress from being in a crowded tank causes poor coloration/loss of color.

Now after spending a few months relaxing in the sparsely populated CPD tank his coloration is decent. Sorry I don't have a "before" pic. There's only one shrimp + reflection in the picture.

Interesting. I may have to try this too. My CRS's white became paler over time and I couldn't figure out why. I thought it was because I moved them to a different tank but you may be onto something.
