Description
Midnight Pygmy Basslet (Manonichthys alleni)
Overview
The Midnight Pygmy Basslet is a sleek and elegant reef fish known for its deep jet-black body contrasted by a bright yellow tail and fins. Compact, hardy, and full of character, this striking species makes a bold statement in both reef and fish-only marine aquariums.
Origin
Native to the Indo-Pacific region, particularly around Indonesia and the Philippines, the Midnight Pygmy Basslet inhabits coral reef slopes and lagoons, often sheltering in caves or sponges.
Feeding
A carnivorous species that thrives on a varied diet of meaty foods such as mysis shrimp, brine shrimp, finely chopped seafood, and high-quality frozen or pellet foods. Feed once or twice daily to maintain vibrant coloration and health.
Tank Mates
Semi-aggressive but manageable in community settings with robust, similarly sized fish such as wrasses, clownfish, and angelfish. Avoid keeping with very timid or tiny tank mates and other basslets in smaller systems to prevent territorial disputes.
Aggression
Territorial, particularly in confined spaces or toward similar-looking species. Providing plenty of rockwork and hiding areas helps reduce aggression and allows for natural behavior.
Experience Level
Best suited for intermediate aquarists. The Midnight Pygmy Basslet is hardy and reef-safe but benefits from a stable, mature aquarium with adequate hiding spaces and consistent water quality.
