With any cichlid, anthropomorphically personable has more to to with you than them, if you get them very young, and you spennd time, get them eating from or associate food with your fingers, they will react accordingly.
If you walk in once a day and toss a little food in, and walk away, I doubt that they will become more than just a fish, with a fish personality.
But a caveat, cichlids have long memories, if you decide to net them out occasionally and they associate you with that, fear, they may from then on, hide when you come around.
It is also probably a good idea for you to get cichlids the go back generations in the aquarium as opposed to wild ones.
