Nice Gex Gav! her tail is rather unusual imo, not alot of spots, looks intresting. can you get a closeup?
Make sure theres plenty of cool space, heatcord should be like just in under one corner. Im not even using any heat here now myself.
Might be ness in winter here you are though. make sure you have a hide at each end, one above the warm spot and one elsewhere.
see how they go next spring having spent winter with a warm spot,
general temps there will likely still be cool enough over wnter.
im going to cool ours this winter, no heat, see if production/fertility rate increases.
how do you find the mulch substrate? no problems with catching food/finding food with it? is it easy for cleaning with them?
Ive found ours all use the exact same corner for popping in, like a toilet spot, makes cleaning easier.
Keep us updated mate.
