Marbled Velvet Geckos Substrate?

[KingsReptiles]

Hi, at next expo im getting a pair of marbled velvet geckos. I know they are mainly arid zone species especially NT and WA forms, so not sure if i should use desert sand in their setup like i do for knob tails, or wether coco peat or critter crumble be better, advice appreciated, thanks

A mixture of sand and critter crumble/coir peat is good as a substrate for geckos.
