I have two reds in separate tanks. They are the same size, but one I got 3 weeks ago and he went from the 20 quarantine tank to the 55 yesterday when in got home with my second red severum. The one I got 3 weeks ago is the biggest fish in the 55 grow out tank (3") and he pays the other fish no attention at all. He is at the front of the tank anytime someone is near. I hope the other one is just as calm and personable.
Good luck growing him out. He looks like he will be super colorful when he is big.
