Beautiful tank set up too. I would wait until you get the ledges to move him in, mostly because you need to be really careful with that substrate that he doesn't end up eating it and getting impacted. I was trying to make a planted set up work for a while but gave up on the project when I thought I saw my crestie eat some dirt for no apparent reason. Just a suggestion, brown paper towels would probably still be pretty nice looking and a lot safer and easier to clean.
Also wanted to mention, I saw u talking a few posts up about feeding roaches. The advice of all the breeders is that unless you are an expert in crested gecko dietary requirements you should feed crested gecko diet, with insects only as an occasional treat. Cresties have very particular requirements and most people will not be able to adequately meet them. In addition to that if you are going to feed live insects AND keep that sub, you really .must. feed him in a different tank. He could easily end up eating the sub (looks like maybe eco earth?) accidentally while lunging for a bug and getting impacted.
I have had my crested gecko Boogie Monster for 13 years and have been using Repashy Crested Gecko Diet the whole time (he's still going strong btw!). It is really very cheap, I only go through 1 or 2 bottles a year and it's the best diet on the market. You can even get it in different flavors if you really want. Once when petsmart stopped selling Repashy I tried their crummy new brand and it was CLEARLY inferior, I returned it as soon as my Repashy CGD came in the mail, totally worth the 2 or 3 extra bucks.
Also ps if you are set on insects and fruit, dont forget to dust with vitamin D3 powder!
Sorry if any of this was told to u before, I didn't read the whole thread as it is kind of long. GL w ur new pet!
