Cute geckos, but you reaaaaallllly shouldn't be housing them on sand for their safety. Sand is quite dangerous as leopard geckos tend to ingest it while hunting prey. Also some as know to just lick it and flat out eat it. I really suggest switching to tile, paper towel or some other flat substrate like that that isn't ingestable. Can you tell us more about your housing and maybe even provide pictures? As a newbie to leopard geckos something's may not correct in your care/housing/temps/feeding, so we can help you correct them if so. Otherwise we can praise you for the correct things
