Substrate = Washed Sand to a depth of around 3 inches
Diet = insects (any) will also eat meat products though many are low in calcium so stick to insects for the most part, whilst growing feed constantly, 1-2 times a week once adult.
Breeding = the hard part is wroking out the sexes, once you have a pair, and they are willing to live together, never seperate them... they will breed and females lay 4 - 6 eggs every 30 days through the warmer months. Best way is to buy 4, raise them up together, as they mature split the fighters and hopfully 1 pair will start laying eggs..
Housing = I keep mine in a 2 x 2 foot tank, though you could go smaller if you wish, large plastic tubs are fine, heat 1/4 of the floor space. NEVER expose them to temps over 30 deg.
