What thala said. Part of being a responsible reptile owner is having an enclosure that will last for its entire life. A ten gallon simply will not suffice. You want to do everything right this time around to give your new friend the best life possible. Patience will pay off in the end. Don't get a Leo just to get something. That ten gallon is too small for a Leo. If you have money for a larger enclosure that is wonderful! But can you pay for lighting, food , enclosure furniture and an emergency fund for a vet trip should a problem arise? You will want to have a fecal done as well.
