My 8 year old niece wants a tree frog for her 9th birthday in sept. I've read that they need a tall tank and the white's tree frog is the best variety for kids but does anyone else have any info?
The White's tree frog is definitely considered one of the easier tree frogs to care for but they still require specialist care. So I would make sure the child does plenty of research and is fully aware of the commitment! These guys can live up to 15-20 YEARS so this is a long term commitment. So whoever is the adult overseeing care must also be prepared to look after this frog for a long time.
It is not recommended to handle them as they have very delicate skin - if your niece wants something she can handle lots then I would consider something else. Frogs are ornamental pets and handling should be kept to a minimum.
Also take into consideration, the animal itself may be relatively cheap, but the set-up costs can be quite high.
