Question: is 10 gallons enough for a leopard gecko?
Answer: A 10-gallon tank should be more than sufficient for this tiny reptile. If you are going to have more than one gecko, the general rule is 10-gallons per gecko. So to house two geckos you'd need a 20-gallon tank, and so on. ... Geckos need access to a moist area to aid in shedding.
