Perch Fish are among the most common freshwater fish. There are 6000 species spread across the globe. These fish have many names depending on where they come from. For example in the Philippines, they call the silver perch “Ayungin” and the climbing perch “Liwalo” or “Martiniko”
The most common species of Perch are the climbing perch, European perch, Balkhash perch, yellow perch, golden perch, silver perch, spangled perch, and white perch.

Yellow perch have the most distinguishing appearance among all the species. They have dark stripes over their yellow or golden body.
Climbing perch have heads shaped like torpedoes and green scales. They got their name because they can climb out the water and use their pectoral fins, tail, and gill cover to move on land. It’s pretty amazing, here’s a video of a climbing perch walking, click here.
If you want to keep perch as pets, I wouldn’t recommend it. putting them together with other fish might result in fighting because perch fish are naturally aggressive. Keeping them in a tank can work but make sure to put a lot of vegetation in there.
