house tree frogs together

[DonLisk]

I wouldn't call any of them easier. It is all setup and then routine.
Setup the tank so it has the environment they need to feel secure, travel around the tank without needing to walk on the substrate, have a water source to soak in, and have the proper temps and humidity.
Routine would be to have a schedule to maintain the tank such as picking up excess waste, misting, draining off excess water, changing water dish, preparing water, and having feed on hand.

Not sure how active the Milk Frogs are but Red Eyes are rarely seen since they usually move in the dark and night lights cause them to usually retreat to hiding or their sleeping spot. Whites care about nothing when they are acclimated and use to you. Whites will trash a plant in no time, dirty a water nightly, and be very entertaining to watch.

Red Eyes are what i would call delicate movers and gently move about a tank whereas whites will dive for things and crash right through, walk over anything in their way, and miss many a cricket ending up with a mouthful of substrate. :-)
