Hello and Welcome. How old is Dexter?
That disc for temp etc, needs to be replaced with a digital and placed lower, at tortoise height. Those disc ones are unreliable and not accurate.
First they should not be kept in a pair, ever
Second, they need to be in a closed chamber enclosure with 80% humidity.
Short time outside daily, about 1/2 hour for now more as they grow.
Your post reads like you are asking if what you cut up and is left on their plate can be saved and frozen.
So yes, the extra cut up, but not what is left over on their plate.
Depends on what it is. I don't know if I would save what is left on their plate as their food should be left out for the day so they can graze on and off as they please. But left over that you didn't feed would be fine. Greens however will turn to mush.
How old is the tort?
A closed chamber is needed for hatchlings up to about 3 years of age or so and 80% humidity. The humidity will not get high enough with an open top enclosure.
Also spraying will not do it
Dampen the substrate by pouring warm water into the corners and pack the substrate...
Might be old and new enclosure but nothing looks big enough for that age leopard. I had to rehab a leopard kept in too small enclosure. He couldn't walk and was way under sized. This leopard needs much better than any picture shows!
OMG, he needs a much much bigger enclosure than that. That's a hatchling size enclosure.
Temps should never go below 80F day and night all over except the basking area.
Basking 95-100F
Please get him into a large, at least a room size enclosure, 8x10 or 10x10 a dedicated room to him or rehome...
First they need to be seperated ASAP never kept in pairs
They need a basking temp from an incandescent flood bulb that reaches 95-100, a tube florescent for uvb and ceramic heat emitter for night heat and any added day heat needed.
Day temps should range 75-80 and night temps not lower than 70...
Two pack on Amazon for like 14 bucks. Not sure what your cost would be.
Not necessary but most likely won't reach the temps for basking that is need with all the heat going up.
The ones with the plastic sockets should be cheaper. Also don't shop pet stores for them, but hardware stores or home improvement stores, like what a Home Depot is. Even Amazon might be cheaper.
But seriously. Turtles and tortoises are slow. Unless you try to feed them with fingers in the way or are talking about the actual snapping species and they are picked up incorrectly, tortoises and turtles are very non threatening.
I always get a kick out of the threads, my tortoise keeps...
It looks like the right kind. But I agree, it needs to be in a dome. The dome can have either the ceramic or plastic socket. Most other types of reptile heat lights should be in a ceramic socket.
How big exactly would each section be?
You would have to separate with a solid non see thru material
@Tom can answer the other part, he has or had many adult Sulcatas housed near each other.
If it's an adult, you can put the orchid or fir bark over top the coir. In my opinion, this gives the best of both worlds.
And, don't forget to hand pack it lol
@ZEROPILOT can help for a proper size enclosure.
I would cover the enclosure with fencing so the dog can't get into it.
As for flooding, either bring him inside when it rains or make the enclosure higher than the yard
Misters or sprinklers would be a better way to get the humidity up. Set them...
You will have to build an enclosure as you won't be able to find a proper one at the pet store. You can try looking for a raised garden bed container to use, a large animal stock watering tank to use or a pop up greenhouse to use, all to be used indoors
Some people will use the ceramic heat emitter like you have. But place it right by the light of it isn't. They bask in the wild by the sun so they look for lighted heat to bask in
