my leo looks really skinny?

I just bought my leo from petco. I bought 2 of them. when I got them they both looked like they were about the same size but now one looks the same but the other one is really skinny. I put crickets in there every night and have pheonix worms and there is always some left in the morning.
Is there something I should be doing??
What is wrong?!?!?!

There is also a very good caresheet that covers everything that a leopard gecko requires It's in the caresheet section.. have a read it's great

Are they in separate cages? if not then one could be eating the food.. and leaving not a lot of the other.
