I keep my temps at 78 and use a thermostat to monitor it. The trickiest part with baby RedEyes is making sure they are eating enough. Make sure there food source is no bigger than the width between his eyes, which usually means true pinhead crickets or the largest variety of fruit flies. Feed him as much as he wants to eat. You can order pinheads from cricket suppliers by the thousand for less than 20 bucks or you can pick them up at reptile shows. A good way that you can tell everything is going well is that you will see baby frog poops everywhere. If he's pooping ...he's eating enough. Also keep three sides of his tank blacked out to help him feel comfortable. If you can post a picture of his tank.
