As Eli said, they only need a small enclosure as babies because they require little space and can even be stressed by an oversized tank. Because of this, a medium or larger critter keeper is fine. Other options include sterilite/rubbermaid clear plastic tubs. For my babies right now I use a 3 stack shelf from Target modified with some holes and heating equipment. Once your frog grows some, your 10 gallon will be perfect. Hope this helps.
