I'm glad that you're learning from past errors. I'm so sorry that you had to experience that.
I think that you'll be pleasantly suprised by how hardy the little Ornate is. I always like to say that it seems they are "born older" than Easterns. They're larger, faster, stronger, and grow more quickly. Your habitat looks like it has some nice humid spots, which is something that many people with hatchling Ornates don't provide...I'm glad that you're not making that mistake. Provide a very warm, dry basking spot. My Ornates go straight to their basking area every morning when the lights come on, and then again after they're fed. Feed generously, varied, and often! Keep us updated with the little guy's progress and pictures!
Good news - guess what one of my very first meals offered to hatchling Ornates is?...mealworm beetles! Hey, it may be time for you to get some sweet revenge
