I have the exact same enclosure as that one above! they're great.
Other wise feed a few crickets every night when young and a little less when adults.
Make sure you feed by tweezers, as if you have enclousers like the one in the video above they will drown. Never use hot water from the tap as it contains iron and is bad for their skin.
Don't handle them, if you do try not to touch their backs and keep their enclosure very clean at all times, make sure they dont dry out.
