A club for owners of Parrot Cichlids

i can't figure out whether or not i really have a parrot fish. the store told me it was and it looks like one but i've also heard that red devils look exactly like them.

My so called parrot fish is bright orange and has white rimmed eyes and very aggressive. my sister has one too, it's orange the same color as mine but its eyes are black and its also not aggressive. i would appreciate it if someone could help me figure this out.
