Still he is a baby they will be defensive. Still keep him in as little stress as possible. He will. Calm down. I see the feistiness as a good thing. When they have strength they fight. However if your temps had not matched up I would have recommended you rechecking everything to make sure the hot side wasn't too hot. I think he's doing fine. Remember to keep things simple.
