Suggestions for improvements and misc questions? (Crested geckos)

[Sphinx]

I have two ten gallon tanks for two juvenile crested geckos, and was wondering if from the pictures something is incorrect or could be added? The lamp is just for show and does not emit any heat. Does anyone know of a good hygrometer that won't be damaged from water? And where can you buy cork flats/do cresties like them? I've included pictures of my geckos as well

The tanks look nice and full of plants and climbing materials. I would make the suggestion of turning them on their sides so that your geckos get more height. They are arboreal and will enjoy the height over the length.
I use natural branches and corks in all of my geckos enclosures and they love to run around on them and hide behind them.
I've not recently had very much luck with the cheaper Hygrometers/Thermometers that I've ordered on Amazon. It seems that they don't last very long. It looks like I'm going to have to spend a bit more on better quality ones.

I've had good luck with the Zilla Digital Thermometer/Hygrometer, and a lot of people I know use AcuRites (although personally I don't like them because they don't have probes).
