Cherry Shrimp Changing color

[zodiak245]

Is it normal for cherry shrimp to lose its color when put into new tank? Does that mean they are going to molt? I put them in 12 hours ago and when I woke up some lost its color.beforeafter

They do change color a fair bit. Lighting, water chemistry, lifestage, food, stress . . . all of these are factors. When they multiply, young shrimp do not always have the same level of vibrancy as adults. In time, some color up very well. Others tend to lean towards wild-type colors over a few generations. Cull if you want color!

If you just put them in they usually  molt shortly after and it takes a bit for their  color to darken after the molt.

Yeah ^^ It probably means they recently molted.

On my amano's, they go from the translucent color to a little bit of a foggy white, then a foggy yellow, then they molt.

Along the same lines - we recognize the shrimp lose color if conditions change, but besides culling what can be done to bring back the vibrant color?  IS it just culling the line or selecting out the best to start out a new line of more vivid colors?  Can you aid this process with additives or food?  My line of Cherry's has dimmed over generations and I am wondering how to bring them back.

Other than culling, the best method I'm aware of would be to introduce superior stock from another source.

I had an odd thing happen. I bought low grade color red like lowest speckled red. Over time I started seeing deep red in a skittles tank where even the legs were solid red. I put some photos in my journal of them but can’t find them atm.
