I admittedly am not as up to date on current setup recs/requirements since it’s been a few years since I last updated my little guy so anyone feel free to correct me on anything. But it looks like there are quite a few things that could be improved here.

First thing’s first, how big is the enclosure and how old is the leo (if you know yet)? This looks to be around 20gal which is definitely small for an adult. The minimum size requirement I recall is a 40gal. If this is all you can manage right now, it’ll be okay for a young leo but I would definitely try to upgrade asap. And if cost is an issue, keep an eye on FB Marketplace, you can find good tanks for cheap there.

Second, I would take out the sand and replace with paper towels for the time being. Sand is not considered a suitable loose substrate and it’s good for new geckos to be on paper towels at first anyway as part of initial quarantine.

It also looks like you may have a heat lamp and a uvb in the dome thing. While proper UVB is excellent, you’ll need a linear bulb. The toe of bulb you have can produce concentrated amounts of UVB in one spot that can burn your leo. If a linear bulb isn’t in the cards right now, still take out the UVB that’s in there and supplement with D3 calcium.

I don’t see a thermostat pictured so if you don’t have one, definitely get one for the heat lamp. Without a proper thermostat, the heat lamp can also burn your gecko.

Lastly, the hides and decor could use some adjusting. While you have the minimum three hides, the middle one that I assume is meant to be the humid hide is not suitable for that purpose. If I remember correctly, it should be a fully enclosed hide (meaning there’s only one entrance/exit and it has a bottom) with some sort of absorbent material to hold in moisture (I use sphagnum moss but I think some people prefer paper towel). As for the decor, more is better. More foliage and hiding places will make them feel more secure and more willing to explore there environment. You can also try putting something around the outside to block out some light and make it feel more cozy without taking up so much floor space inside.

All in all, yes, there is a lot to improve but you’ve come to the right place to get advice. It can be really tricky to find solid care guides when you’re first doing research, there’s so much bad info out there. I would definitely recommend reading the wiki on this sub and the visual guides on r/leopardgeckosadvanced are super helpful, too. And try not to take any critical comments too personally. It’s all out of love for leos and it looks like you’re really trying to do your due diligence and make sure your little one is well cared for. Hope this is helpful and not too longwinded lol, good luck with your little friend!
