PeeWee, because they're ornery yet can't defend themselves I only keep my Parrots with other Parrots. If you put them in with other cichlids they'll start a fight but can't finish it because of their mouths. If you put some sort of bottom feeder in there chances are they'll stress it to peices picking at it. It wouldn't be hurt physically but it'd be stressed to death.
I have a blood parrot in my mish mash of a tank and he does fine with all the other fish. He kind of keeps to himself and doesn't bother anyone. Also, he's pretty fast, so if someone goes to pick on him, he can get away.
Is the 16" aro in the 60g? That might be a problem.
