American green tree frog enclosure size

Arboreal — vertical height first. An adult american green tree frog should live in at least 18" L × 18" W × 24" H; we build toward 18" L × 18" W × 24" H (1.5 × 1.5 × 2 ft, roughly 2.3 sq ft of floor and about a 34-gallon glass equivalent).

Height matters most; a small group fits an 18×18×24.
