Blue Crayfish Molting Timeline

Yeah, it would have been hard not to notice the size difference after mine molts. So far she has gotten at least 1/3 bigger after every molt....2X bigger for the first three or so. Maybe your water is too cold...I've heard that can cause problems with shedding. It really depends on what species you have though. Do you know what kind it is??

Well its definitely not too cold in your tank. I don't think they ever stop molting altogether so maybe he is just older and only sheds once in a blue moon. I just read that particular species usually grows to a max length of about 5".

I bought my cray for pretty much the same reason. At the time I didn't know blue crayfish even existed and I thought it was cool, so i bought her. I got lucky IMO though cuz she turned out to be an Australian cray that gets really big.
 
Any updates on this time line? This could actually be a fairly good way to age a cray, see how long it takes between moults...
 
My C. Quad hasn't moted again yet but I did notice something different about her last night. She's guarding a whole clutch of eggs under her tail. I've had her since she was only about two inches long or so and her only tankmates have been feeders and a bgk, so no mating has occurred for sure. Is it normal for them to produce unfertilized eggs?
 
BTB, I know this thread started awhile back but I've enjoyed reading it. I've got 7 Crays now and have a list tacked to the wall with each of their names and the dates they moult. I love peering into each tank every morning to see if there was any midnight moulting going on while I was asleep :-) I've got a male C. quad about 6"-7" (without claws) I've had him a couple months, he's only moulted once so far.
I don't know if it's normal for them to produce eggs without a male present but I'd guess it is. Fish can lay eggs even if there's only female fish in there.
