I've had crayfish for about 2yrs now. I've bread my crays and everything. Now all of a sudden I have a case of shell rot in my tank 
. I have it on 2 of my female marbles..... What should I do? And how can I treat it? 
Side Note: This is my display tank.... So I have allot of crays in the tank.... My Blue breeding pair is in the tank....
Should I be worried.... Allot of blues are in there.....
