I have a colony of Novemessor Cockerelli with a queen and about 20 workers with a low 5 wattage heater underneath to generate a little bit of heat/humidity for the queen . They're doing great, but I've also decided to add a ceramic heater from above, as recommended to me. I have it all set up and bought a 100 watt ceramic heater bulb, but I'm wondering if that's too strong. Any suggestions on heat wattage I should use? FYI, I"ve attached a photo, and in it, the ceramic heater is about 4 inches from the top of the foraging area, which is about 8 inches from the main part of the formicarium.
FYI I had to convert the photo to pdf to upload.
