My lateralis & my glass dubia tank have a infrared heat lamp on them at night. During the day they are at current room temperature, but with temperatures dropping I have been leaving the heat lamp on all day. My worms & my other dubia bin are sitting on top of my 75gal monitor tank. They are each next to one of the heat lamps on top of the tank, but they are only on during the day & have room temp at night.
I am hoping to get some flex watt heat tape for them soon so I can maintain a steady temperature for them. I think that would work best.
I am getting ready to do this and was going to just use the zoomed 8 watt UTH I have on a 10 gallon tank. I would think it would be ok since it never could get the 10 gallon floor above 85....
