That's what a wild Oscar looks like? AWESOME! The 3rd is a Guinean Barracuda. Its the 2nd largest Barracuda species and considered the most powerful. IGFA allows for a full 130 lb test line to target that species.
The oscar looks like an Astronotus orbicularis.......the regular oscar is an astronatus.... sometimes people sell the orbicularis and crassipinnis....look on www.tangledupincichlids.com in the photo gallery
