Baby Bearded dragon didnt eat today and is in deep sleep?

I bought my bearded dragon yesterday with the cage already set up. The temps showed pretty good although the cool side was around 70. I have a 20 gallon long for now ( its a baby) with a 75 watt bulb and a reptisun 10.0 He ate yesterday but did not eat at all today. I know I am probably paranoid but I just want to do everything right. He seemed very tired tonight and when I put my hand in the cage I almost full picked him up without him even opening his eyes. I am not sure how deep of a sleep they go into but this seemed pretty deep. He did open his eyes eventually. I just want to make sure everything is ok. Like I said he did eat the day I brought him home and quite a good amount too. I have a digital probe thermometer that says its over 100 in the baskin. I will give it another day but I was just wondering if there were any signs I should be aware of and act upon immediately. Thanks a lot for your help
