well mine are only about an inch to 2 inches long each so they are tiny....and what substrate is best....bed a beast ..soil ...moss..wood chips...
also you said food bowl ..how do i ge tthe crickest to stay in there....cause they dont eat the crickest for about an hour after i put them in there...no matter when i put them in i have even tryed puting them in at different times and the crickets are there for about 30 -45 minuts befor they eat them its strange
also i have found that they will not eat dead crickets mixed with baby food and they wont even touch it
