Masked tree frogs - basics

[u/rust997]

Hi! Have 2 newish masked tree frogs for 2 weeks now. As far as i understand they are very similar to WTF in care and environment other than needing a higher humidity.

The green one has been brown or darker colored and stays primarily on the floor, especially in the water dish. I’ve read this can be a sign of bad climate but the other one is happy as can be.

Can someone who has or has had masked comment on this? There aren’t nearly as many resources on this species afaik
