Recommended Vivarium Size: Crowned Tree Frogs are medium sized frog and will need a larger habitat.  As a tree frog, they will want a tall enclosure.  Exo Terra Glass Terrarium 18x18x24 or 18x18x36 are good for groups up to four.  Adult Crowned Tree Frogs like being above water.  A paludarium would work best.  Make sure to include a large ground spots for feeding crickets and spots for the frogs to be out of the water.
 
Temperature: Range of 70 F to 80 F, are recommended temperatures.  Temperatures in the mid/high 80's can be fatal.

Sexing: Finn's Frog Farms sells unsexed juvenile frogs, least three months out of the water.  The females are much larger and more rounded than the male frogs.  Males will call when in a rain chamber.  
 
Color/Pattern: Crowned Tree Frogs are grey as froglets with black and gray banded legs.  The spines on their heads are not on present when froglets.  As adults the colors change to light brown/bronze and darker chocolate brown.  The spine (crown) will develop as they get older.
