Can you put leopard geckos on sand once they get older
No, most gecko owners don't know this but it can cause impaction and ultimately death. Use damp paper towels or coconut fiber or the green grassy substrate
No impaction and PARASITES are majr problems with sand. U can't sterilize sand it breeds parasites. Put them on paper towels or this green carpet terrain.
Use reptile carpet or even felt. Coconut fibre and sand are very bad
