Arboreal — vertical height first
Amazon milk frog enclosure size
Arboreal — vertical height first. An adult amazon milk frog should live in at least 18" L × 18" W × 24" H; we build toward 24" L × 18" W × 36" H (2 × 1.5 × 3 ft, roughly 3 sq ft of floor and about a 67-gallon glass equivalent).
Height is the priority; a pair fits an 18×18×24.
