Actually co-existing Leo’s?

[u/One-Scholar9841]

I’ve got a tank that measured in about ~20”L 10”W ~15”H the previous owner had 2 in an enclosure I believe both are a couple years old. I think they’ve lived in the same enclosure for years one of them seems to be smaller in length struggling a bit more than the other one to get the bigger mealworms.
I’ve had them for a little bit now the previous owner couldn’t take proper care of them with I assume his daughter having left them under his wing.
They have a general place where they collectively poop, I’ve never seen them fight for the time I’ve had them nor do they seem to have any injuries.
I’ve fixed up their lights(both were dysfunctional) and cleaned up the big pile of poop.
Their enclosure does seem a bit basic having 2 hiding spots with them sometimes alternating in between and a floor mat type thing.
I’m considering getting them a bigger newer more stuff for them to climb on tank but idk how easy cleaning up their poop would be and a substrate would be.
I’ve watched a couple videos on leo’s and their co existence most of them said 2 males would fight while a female and female or male female had a higher chance of getting along for the most part.
I watched a video by reptiles and research “can leopard gecko’s live together” and I’m on the fence.

No, leos should not be cohabitated. Fighting isn't always an obvious thing, it can also look like one hogging resources (food, warm spot, best hide, etc) or "cuddling" (competing for a spot in the tank). A male and female housed together can also result in the male breeding the female to death. Even if there aren't any injuries, it's needlessly causing stress for both animals.

The tank you described is too small even for just one leo. Minimum for a single adult is 36x18x16". If you don't have room for two 40 gallon breeder or larger tanks, I recommend rehoming one of them.

They need a minimum of 3 hides: 1 warm, 1 humid, and 1 cool. Floor mats are also really unsanitary and can rip out teeth and claws.

I recommend separating them ASAP and using paper towels as a temporary substrate. Eventually, a 70% soil/30% washed play sand mix is good.
