It's either a spotted tilapia or Mayan cichlid. Either one are good feeder fish for PB.
The spotted tilapia I catch in Miami have bars when they are small. The bars lose their outside edges and ends up with spots along the center of the body when they grow.
The mayan cichlid also have bars and a dark spot on its dorsal. They also have a dark spot on the caudal as well. Similar to PB's ocellaris but a different color. They keep their bars when they get big.
