I had mine in a simple set up. Around 6" sub with a washing up bowl as a water dish. They don't really move apart from eating. I ended up putting my male in a 2ftx2ft tank as he really didn't use the larger tank I had him set up in.
Mine could happily eat 15-25 adult dubai roaches in a single sitting. I'd also give him morio worms and the occasional rat/chick. They need to be mainly fed inverts for a happy and healthy life.
You need dechlorinater for the water and vit/calcium dust for the feeders.
I fed Rancor in a separate rub when feeding him inverts to stop him ingesting large amounts of substrate.
. Well not really. But they like to crawl and chew on bark and sticks. Those fake plants are full of small nymphs. If I mist the tank it turns black with babies. I only mist for their drinking. They are fun to watch.
