She's in the same 33 litre RUB rack as all my others, temps 32-34 degrees C. I've been misting her daily this week as she's had a really bad shed. With the mites I've treated all my snake tubs/hides/bowls several times with a hardcore mite spray and given her a good a few good soaks, though it's taken a couple of months to get rid of them (every time I think they're gone, I check on her and they're all over her again, a real pain).
Had a few bad weeks where all but a couple have not eaten - figured maybe it's the recent temperature drops (I'm in London). I might try her on a few live feeds to get her started again and see if that helps...
