The frogs will be better if they have branches to climb on and some leafy things to hide in. Cover the walls for their tank with a garbge bag or craft paper to help them settle in. Giving them some privacy. keep the tank darkened for at least a week preferable 2 and then remove one side at a time. Try not to handle the frogs at all while they settle. Just drop a few crickets in their tank and keep an eye out to see if they eat them
