Jaguar Cichlid Tankmates?

i just bought a new 125 gallon aquarium about 1 month ago and now have a 4.5 inch african tigerfish, 4 inch indo datnoid, 5 inch ornate bichir, 3 inch red oscar, two 3 inch pea b, 4 inch red bellied pacu, 6 inch silver arowana, and my old 13 inch pleco. i wanted to add a jaguar cichlid because i used to have one a while back that was about 12 inches and he was beautiful but i had to sell him because i was moving to a new house at that time. would these fish be good tank mates for a 2 inch jaguar cichlid. PS. my buddy has a 1200 gallon aquarium that he used to use that he is gonna sell me when the fish outgrow the tank.
