Whites Tree Frog sleeping at the wrong time.

[EZweasel]

I have four whites tree frogs in a terrarium. Every night when I feed them all but one comes down from their perching area to eat, except one. He does not come down to eat until morning arrives. He stays asleep until about 7:00 am or so and stays awake for a while then goes back to to his mushroom cliff. He does not look unhealthy, but for some reason is awake at the wrong times. Any reason I should be concerned?

That doesn’t sound like normal behavior for a WTF. Maybe there is something going on internally, to where illness/disease is undetectable by the unaided eye. Do you know how old your WTF is, because old age may play a factor in his odd behavior.

I could be he doesn't want to compete for the food and has open tank by himself for finding crickets. I have one that will not take crickets when hand fed but the other three will. He'll even watch the others eat and stays put.
