My geckos climb like it is their job
Nice pics by the way above.
I tend to feed my leos two to three insects a day depending on the size. I despise crickets and prefer dubia. Either way I dust the food once a week for nutrients. Also you can get a calcium powder to put in their. Your leos could use a hot spot in their cage as well..... be careful if buying a heat pad. you will want to go to home depot or something and get a dimmer switch. the pads get super hot and can burn your reptile. The dimmer switch allows you to control the temp. I also recommend a temp gun. (ebay) they allow you to check temps of different places in the cage as well as of your animal
