I feed mine crickets, 10-15 crickets 2-3 times a week, dusted with calcium powder every other feeding. Mine was $15, ive never seen one for higher than $20. I house mine in a 20 gallon tall exo terra terrarium, the ones that open in the front (the enclosure in the pic is smaller than a 20 gal im about to get a bigger one)
Mine was aggressive in the beginning, but i bought a pair of gloves and took it out once day (You don't have to use gloves if it's a baby) and handled it with the gloves on. When she no longer was bothered by me handling her, I decided to take the gloves off and handle her, and everything went fine! So now I handle her gloveless and she's not aggressive at all.
