good to hear you got extra supplies. I would just go down to petco or petsmart even though i despise those places for their poor husbandry techniques. but you can pick up a 10 gal for like 10 bucks that would be perfect for a baby ball. (im assuming its a baby) Then later you can go for a larger enclosure. I have all my balls in 60 gal tanks and they couldn't be happier or healthier. whatever you choose to go with later down the road is up to you a 30 long would be perfect for an adult. well good luck
