Why do you have 2 heat lamps on top of the cage? Are you having trouble with keeping his temps up? Also, he'd be happier in a 24x24x48 cage, but yours looks nicely planted so kudos to you for that! He's a great looking veiled, btw!
I have a 2 1/2 feet wide, 4 feet long and 6 feet high cage for my juvenile veiled. I have one heat lamp, 75 watt and one 18" uvb linear. He hangs out under the lights when he wants them. So you probably don't need two heat lamps on a cage that small.
