my marble turn blue?

[Mr.Kiet]

So recently, my new batch of baby marbled-crays are blue... and a few adults also turn blue after they molted (some turn blue on the head, some on the claws, and some on the legs, although, 1 turn completely blue). Is this bad? Something I should be worried about? Also, have this happen to anyone? BTW, water parameters and diet remain the same... although the weather kinda dropped a bit because it's starting to get cold around my neck of the wood and my furnace is broken but will get replace soon. HELP!

My marble is turning blue as well. All her legs, both claws, and part of her carapace are now blue. More blue is visible with each molt. Most likely related to diet, nothing to worry about. As of now, her first batch of babies are all brown.

Nothing to be scared of. Procambarus crayfish (Alleni, Clarkii, Mamorkreb) all have different color morphs. I've noticed my Alleni' changing color after molt too, they will do it from time to time and vary in different shades of blue or brown.

Curious though, what colors were the parents?

 

[Mr.Kiet]

The parent is brown.

There are both brown and blue marbled crayfish. I bought baby blue and brown ones yesterday at the TCA auction.
