k cause (I know they are diurnal) every night when I turn the lights off about 2 mins later I hear a chatter like call from their tank and I am wondering what it is. I switched their light back on and one male (?) is perched wide awake on top of a rock all puffed out like he may of just been singing. Maybe he's practising and getting it all wrong
