I wouldn't add anything that's not needed. It doesn't look very big and he needs to be able to walk around. I had to rescue a leopard that couldn't walk because he was kept in too small of an enclosure so he couldnt build up muscle strength. Hard to tell though by a pic what the true size is.
I don't see a water dish or a food tile.
I did find what I think is the water dish. Looks too small for him. It needs to be big enough for him to get into it and self soak if he wants. A low sided clay saucer works the best.
Yeah the dish I have is temporary. I've been soaking her daily but will get a bigger one. It's a 40 gallon on a shelf. I know it's also going to need to be bigger. I'm just thinking about right now. I'm able to hold humidity roughly to 84 and temp at 78 degrees all night without a heat source on. Just thought maybe a way to hide her more or things to explore.
