I have removed the 60w moonlight bulb and replaced it with a 25w day bulb. I've also added a lucky reptile heat mat to the side the viv attached to a on off thermostat. There is currently no night time viewing bulb. I have added the bowl... But no joy last night. Should I remove the uneaten crickets or just leave them at the bottom of the bowl and chuck some food in for the them so the crickets don't die.
