Hi Hobbo,
They're great little lizards. Substrate is a matter of debate for Angle-Heads. Some use newspaper, others use gravel, others still use astroturf. I use astroturf - the main criticism against it is that it can harm the male's hemipenises. I've never had that problem myself. Ideally they requre an enclosure that is taller than it is wide. They will spend most of their days perched on vertical branches. I actually keep mine now in a 18 x 18 x 24 Exoterra. They don't need any heating - except maybe during the winter months. Certainly I wouldn't be letting the temp get much over 28 at any time of the year. I give mine a spray once every couple of days and they seem to enjoy that. They are almost wholly insectivorous in my experience; will readily take wood roaches and crickets. They can be very tolerant of handling with persistence and of all the lizard species, have one of the brightest and most intelligent personalities. I've often likened them to the 'nosy neighbours' of my herp room...
