exactly.

At the minute, mistakenly we bought a faunarium (is that right?) through pet shops (money grabbing) advice.

Its small, 13 inch by 7 inch. Snake is only 12 inch. Anyway, we are learning and I wouldnt put the snake in without the temps being right. So, if the heatmat doesnt heat it properly, we will move it into the bedroom where room temp is around 20c (68f). However, Our 3ft viv arrives tomorrow. We can use Over head heating for this. So we will be ok either way. Just trying to do this right.
