Thanks for the reply Marie.
As far as I have seen, they aen't rolling ont he floor or anything but the male is showing a LOT of interest in the female especially sniffing her cloacal area which she has a MASSIVe problem with

The noises are pretty much a mix of crabbing and hissing but I have also noticed the female is making a barking call type noise too after about an hour of them waking. This isn't a "feed me" call as they already have thier food in for them when they wake up so I am unsure if she is maybe teaing the male if that is something they would even do!
The male is slightly larger than her and doesn't appear to be acting aggressively towards her but is just showing a larger amount of interest.
Is there anything I should be keeping a eye out for? Obviously, I checkt hem daily just inc ase they have actually fought and someone is hurt but other than that, what can I do?
