This is a species I really want to see. I've contributed to the Manchester Museum's Lemur Leaf Frog project some years ago, but never saw it in any zoo. None of the ranariums I visited in Costa Rica and Panama kept it.
I was expected to see it at the Vattenmuseum in Stockholm last year, but this aquarium closed permanently just a few days before my arrival in Sweden... ZTL listed Lemur Leaf Frog for Köln and Antwerpen, but I guess the frogs were kept off show as they weren't anywhere to see.
@AWP As they are nocturnal they are very hard to see in a zoo exhibit. I peered into many vivaria in various collections before @devilfish pointed one out to me at Newquay.
It took me years to see my first. I’d recommend taking some time to study the undersides of leaves in any exhibit they’re in. That’s where they’ll usually be found.
@AWP as Jay said, they like to sleep on the underside of leaves. I personally like this species a lot, and hope their inactivity doesn't turn zoos off of them moving forward.
Being nocturnal isn't really a problem. For example, Artis keeps the related red-eyed tree frog in a darkened terrarium and this works quite well. Sometimes the frogs are sleeping, but often at least one of them is more of less active.
