you don't even need a glass tank just use something even a wooden box or a plastic box... buy some of the the biggest ones you can (most if not all will already be pregnant) and put them in the box with some cardboard egg cartons. put some cut open potatoes in it as they're water source or just dampen the egg cartons. also you can feed them otmeal.
i gave some of these full size crickets to my baby monitor lizard and i guess he didn't eat them all and i ended up seeing baby crickets aroud his tank!. Also on ocation i give some to my turtles and when they bite them the eggs fall out.
to get the breeding going quicklybe sure to get the largest crickets you can'
good luck
