What type of frog for a 5.5 gallon?

[tjtreefrog]

I think you've misunderstood my gecko is in an 18/18/24. I'm wondering what I could fit in a 5.5 gallon it's like 16Lx9wx11h. It's tiny lol

Yes, I'm sorry, that was a misunderstanding on my part.

Now, in his book, Tree Frogs, noted author and founder of Amphibiancare.com Devin Edmonds clearly states that a 10 gallon aquarium is large enough to house a group of 5 Clown tree frogs. Would it just be naive to assume that a 5.5 gallon enclosure would be large enough to house one Clown tree frog? If I am mistaken, please let me know.
