[Ebook] 500 freshwater aquarium fish – Miscellaneous Fish – Perch (Perca fluviatilis)

The Perch can be identified by its distinctive body markings. It has six or more bands on the sides of its body and a black blotch behind the first dorsal fin. Its pelvic, anal, and caudal fins have reddish coloration. Its back is humped behind the head, and it has a large mouth. The caudal fin is slightly forked and the first dorsal fin has up to 1 7 strong spines. However, although it can tolerate a wider temperature range than other members of its family this beautifully marked species is best reserved for the specialist.
