We have a a beautiful new adult White Claw Crayfish in our tanks. She is bright blue in colour which is very rare and thought to be a recessive genetic trait.
As part of their life cycle between May and October Crayfish need to moult their shell to grow. Overnight our crayfish has shed her exoskeleton which is left in the tank and she is an even brighter blue than normal.
The photo is from yesterday before she moulted.
