Common name: Bownband perchlet

General information

The Plectranthias nanus, commonly known as the Dwarf Perchlet, is a small and colorful member of the Serranidae family. This species is appreciated by aquarists for its vibrant hues and manageable size, making it a suitable inhabitant for smaller reef aquariums. Dwarf Perchlets are relatively rare in the trade, often commanding a higher price due to their scarcity and the challenges associated with collecting them from their deep reef habitats.

Care

Caring for Plectranthias nanus requires attention to detail, as they thrive in well-established aquariums with stable water conditions. They prefer a tank with plenty of live rock for hiding and hunting microfauna. A varied diet of small meaty foods, such as mysis shrimp and finely chopped seafood, is essential for maintaining their health and coloration. Due to their small size and peaceful nature, they should be kept with other non-aggressive tank mates.

Reproduction

Little is known about the breeding habits of Plectranthias nanus in the wild or in captivity. However, like many marine fish, they are presumed to be pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs.

Habitat

Plectranthias nanus is typically found in the Western Pacific, from the Philippines to northern Australia. They inhabit deep reef slopes and drop-offs, often at depths beyond typical recreational diving limits. This preference for deeper waters contributes to their rarity in the aquarium trade.
