looking good, the only thing id change is put big white pebbles and leaf litter over teh gravel u have, you'll find they dont aim all that well and end up with a big mouth full at feeding time, my guy spat most of them out but i did find the small stuff in his poo. got worried, hence the substrate he cant swallow.
mine lives on a snake enc so his water is naturally heated a bit anyway, just a thought if u have snakes.
mine is in our lounge room so the house is heated and the tank keeps temp of around 25 degrees they seem happy enough and im going to go and get some bigger pebbles , thanks for the input , much appreciated
