The Perch has two dorsal fins, the first dorsal fin being spined and having a conspicuous black spot to the rear The Perch with it's colours ( greyish olive green on the back ) and markings (darker diffuse bars on its flanks ) easily camouflages itself into it's surroundings, weed beds, sunken branches and tree roots. The lower fins and sometimes the tail tip are tinged with red .These colours and markings are less distinguishable in older specimens who tend to favour deep water and solitude, their colouring being darker and the markings indistinct.
