One thing I just noticed is it looks like (correct me if I'm wrong) that the thermometer probe is by the water and that temp is warm. Usually, you want the water to be on the cool side. And you want at least 1 hide on the warm side. You should have at least 2 hides, one on warm side and one on cool side, but more are better. Also, some fake plants can provide ground coverage that makes snakes feel more secure. They like having lots of places to hide in. And some branches to climb would be great too.
Once again, very cute snake! Best of luck
