My older gp seems lonely and not active?

so i bought him a 10 week old male and introduced them today there is alot of activity now my adult has come out of his shell and seems active they share food toys cage and make lots of cooing noises, there is also alot of chasing and climbing on the younger one by my adult i dont have much gp experience but im quite worried as i have been told they could fight and hurt or even worse dead. they have been together now for 3 hours and althought it look likes the little one is getting pestered by the adult there has been no agression at all. any advice would be most welcome. thank you
