not eating

[Killzone3265]

skittles hasnt been eating since i had to replace a dead reptisun,when i ordered a new one they gave me a 5.0 on accident, so i have to wait a day or two until i get a 10.0
i know the 5.0 wont cut it, so i've been bringing him outside for around an hour and a half to soak in the sun. i have no clue why he isnt eating, but, i noticed that the last few days he has been having small poops, even after eating a mass load of crickets. do you think he could be impacted a little?

ok so he has eaten a little, he has zero interest in hand feeding or tongs right now, i just left some crickets (i killed them so they stay in the bowl lol) and around half an hour later when i came back they were gone, i dont know what his problem is
