It doesn't look like my roaches are eating.. I have an orange slice , a tiny cup of chow, and some turnip green stalks with some leaves left on them that I had left over from my beardies salad.. The temp is good.. Warm side is in the 90's.. Cooler side in the 80's.. That's where the food is.. Should I have the food on the warmer side? Or are they eating and maybe I'm just not able to tell..
