Looks like a bream but has more scale rows (7 rather than 5) above the midline. The lips are a bit thicker than the bream, the head is a little more blunt and the body has more distinct striping.

Fortunately, I was able to spot and sneak up on a couple of large pickerel lurking on the edge of the basin.Chain PickerelEsox niger Morrison Springs ParkWalton County Florida, USAOlympus OM-D E-M5 14-42mm II Lens PT-EP08 Underwater Housing, PPO-EP01 Lens Port & Sea Life Sea Dragon 2000 Underwater Light
