Manyline Perch

Manyline Perch (Plectranthias inermis) – Rare Deepwater Reef Fish

The Manyline Perch (Plectranthias inermis) is a rare and beautifully patterned deepwater reef fish prized by collectors and reef enthusiasts. This striking species features a vibrant orange to reddish body covered with intricate horizontal striping and delicate line patterns that give the fish its distinctive “many-line” appearance. Its compact body shape and subtle elegance make it a standout addition to specialized reef aquariums.

Native to deeper reef slopes in the Indo-Pacific, Manyline Perch are naturally secretive fish that prefer aquariums with plenty of rockwork, caves, and shaded areas where they can feel secure. Once acclimated, they often become more visible, hovering near rock structures and darting out to capture passing food.

These fish thrive in peaceful reef environments with non-aggressive tankmates. A varied carnivorous diet including mysis shrimp, copepods, finely chopped seafood, and other small meaty foods helps maintain their health and vibrant coloration. Due to their deepwater origins and shy nature, they do best in stable, well-established aquariums.
