I have a 7.5 gal upstairs for weekly feeders and I have a UTH that is stuck to the outside on the side of the glass, and seems to do just fine. I would try taking the cardboard off the bottom, you have egg flats standing on their sides right? if the heat is enough it should rise up thru the glass and "thru" the egg flats.. If not you need more heat.
Yeah the egg flats are standing upright. So is it ok for the roaches to be directly on the glass?
They will crawl up into the egg flats so its ok. You will know if they are cold if they are closest to the heat source. If they are nicely spread out then they are happy, but if they are all crammed near the heat it needs to be hotter.
Yeah that makes sense. They were all crammed together literally on the floor. If the glass gets too hot what do I do about food? I have all the food on one side on the floor, will they be able to get to it?
Put the food furthest from the heat so it doesnt rot fast or dry up to quickly
Yeah I know that but would the hot glass stop the roaches from going to the food?
Because my heat mat covers the whole bottom of the tank
That I don't know because I've not had this situation. I know Dubia can tolerate high temps but I don't know what is too hot.. You could cut a piece of cardboard to put down under food and over enough to reach egg flats. The thing you would then need to be aware of would be is the little spaces between the cardboard the nymphs could fit in..
I’ve decided to just move my colony to a Rubbermaid bin haha. I think I’m overthinking this way too hard and everyone’s using bins so that’s what I’ll do. It just seems way easier. I don’t have to worry so much about what to do with the flooring.
