Thanks everyone
He's in a 75g with a Polypterus senegalus, 9 clown loaches, and one young Cuban cichlid. Oh yea he's only almost 8" TL and close to 2 yrs old.
I was able to successfully bred him to a 6" female twice in the past thru an eggcrate divider.
As for the hump is can be a number of things such as good waters, food, genetic, dominance, etc.
