Sleepy Red eyed tree frogs and brown spots

[Frogs1]

Hi, I have 3 Australian Red Eyed tree frogs that I've had for just over a month . Now unlike my Whites tree frogs and magnificent tree frogs, they are only active for about 1 - 2 hours a day. They wake up at 7:30pm when I feed them and they eat, drink and 1 hours later they just go sit on a leaf of or on the background untill 5:am the next day when they then move to there normal sleeping spots, but sometimes they will just go to there sleeping spots straight after eating and sleeping for almost 22 hours. Is this normal for Australian red eyes? It is Summer in Australia as well.

Also one of the red eyes has 3 brown dots on his side, I can't remember if he had it when I got him, but are these normal or are they a bruise or some kind of bit mark? The photo quality isn't the best.
