Ghost Crayfish Not Molting

HI everybody,

Ive had a ghost white crayfish which when sold to me the guy insisted was a freshwater lobster which led me to conclude its a Australian Yabby - Cherax Destructor but now I'm believe it is more likely a Procambarus clarkiI but anyways ive had him(or her ) for a bout a year now and he had molted about 4 - 5 times in the first 2 months I got him felt like rapid fire molting I couldnt believe how quickly he was growing but now it seems its been more then 9 months and I have yet to see him molt again ( ever since his "adult' claws came in). Is this something I should be concerned about or is this normal ? And is there anything I can do to encourage a molt ? Finally here are some pictures !

Before final molt ( still has juvie claws)



Just After final molt ( adult claws)

It's totally normal for their molting to slow waaaaay down once they're fully grown. There's not anything to worry about.

 

Alrighty thank you ! full grown as in reach maturity? Because I was under the impression he still had a good 6 inch of growing to do was it just kinda of a fluke that he molt so quickly intially then ?

Yeah, it seems like your crayfish is fully grown. Procambarus clarkiI doesn't normally get too much larger than three inches from nose to tail. It's normal for them to grow rapidly when they're young, but once their adults, it can slow down to even once a year.

 

Oh really eh ? Good know I was under the impression he was going to reach 12 in + and was worried about scrounging together a bigger tank for him, good to know definitely, thank you again !

 

You're welcome!
