Answer

Congarts Romijee and Sushant. Yes it is Anableps anableps which have a split eyes, thus the fish is able to look above and below the water surface at the same time. Its split retina has two regions. The ventral region, enabling it to see above water and the dorsal region, allowing it to see clearly below water. For this reasons, this fish has been more commonly called the “Four Eyed Fish”
