based on the ones i have, they dont like humidity much higher than 60% and they really enjoy fresh air. Also, they do like to swim at nighttime if they have the option. Mine run around the glass quite often (i have 3 in a 55 gallon so there is plenty of room)

There isnt much information on them.

I did get a very helpful article from one of the members on here that i can email to you if you PM me your email... it has about all the info i can find

There is only 1 recorded breeding in history in captivity (that doesnt mean there arnt others...but its rare lol)

The females and males are more than happy in groups so if you have the ability to get more go for it. The frogs are considered vulnerable by the IUCN because of deforestation in Tanzania

The calling sounds like a small clack or peep... my male has done it rarely.

How large are yours right now?
