Kristen and Brian are correct. 5 gallons is too small for 1 frog let alone 2.... TEN GALLONS per frog is correct. check craigslist for good deals on a tank. a 20 gallon high would be fine for them. also petsmart is having a sale on exo-terras and they are the cheapest ive ever seen them. $79.99 for a 18x18x24. plus you wouldnt have to get it shipped
