Tree frogs are often bought for their looks and then kept in a leftover reptile tank that doesn't fit how they actually live. They're arboreal, nocturnal and need a humidity cycle rather than constant dampness — closer to a dart frog's needs than a leopard gecko's.
Height over floor space
A pair of red-eyed tree frogs or White's tree frogs needs at least an 18×18×24 in front-opening terrarium, planted densely enough to give them leaves and branches to rest on during the day. Floor space matters less than vertical climbing routes and resting spots at different heights.
A nightly humidity spike, then dry-down
Mist in the evening so humidity climbs to 70-90% while the frogs are active overnight, then let it drop toward 50-60% by the next evening. Constant saturation with no dry period raises the risk of skin infections. See our misting vs. fogging guide for which approach fits your schedule.
See misting systems on Amazon →Expect nighttime activity, not daytime
Tree frogs sleep pressed flat against a leaf or the glass during the day and become active after lights-out. Feeding and most observable behavior happens in the evening — this is normal and not a sign the frog is stressed or unwell.
Live plants that tolerate constant moisture
Pothos, bromeliads and broad-leafed tropical plants that can take being climbed on and misted daily work well. See our plant guide for a fuller list by moisture tolerance.
This is a general overview, not species-specific care. Requirements vary between tree frog species — cross-check with a current care sheet before buying.
