Fourmanoir's Perchlet (Plectranthias fourmanoiri) – Complete Care Guide

General Information

The Fourmanoir's Perchlet, scientifically known as Plectranthias fourmanoiri, is a small, colorful fish that belongs to the Serranidae family. This species is a hidden gem in the aquarium trade, prized for its striking red and white coloration and compact size. Native to the Indo-Pacific region, it is often found in deeper reef environments, making it a rare and sought-after addition to home aquariums.

This species is named after Pierre Fourmanoir, a French ichthyologist who contributed significantly to the study of marine fish. Its vibrant red bars and contrasting white body make it a standout choice for aquarists looking to add a splash of color to their tanks. However, its rarity in the trade means it is often considered a collector's fish.

Care

Fourmanoir's Perchlet is moderately challenging to care for, making it best suited for intermediate to advanced aquarists. It thrives in well-established aquariums with plenty of live rock for hiding and exploring. This species is shy by nature and appreciates a peaceful environment with minimal competition for food.

A tank with stable water parameters and moderate flow is ideal. The Fourmanoir's Perchlet does not require a large tank due to its small size, but ample hiding spots and a well-structured aquascape are essential to mimic its natural habitat. Dim lighting or shaded areas can help reduce stress and encourage natural behavior.

Diet and Feeding

In the wild, Plectranthias fourmanoiri is a carnivore, feeding on small crustaceans and plankton. In captivity, it should be offered a varied diet of high-quality frozen foods such as mysis shrimp, brine shrimp, and finely chopped seafood. Enriched foods and occasional live offerings can help maintain its vibrant coloration and overall health.

Feed this species small portions multiple times a day to replicate its natural feeding habits. Ensuring that food reaches the lower levels of the tank is crucial, as this fish tends to stay near the substrate or among rocks.

Behavior and Compatibility

Fourmanoir's Perchlet is a peaceful and reclusive species, making it an excellent choice for community tanks with other non-aggressive fish. It is best kept solo or in a pair, as it may become territorial towards conspecifics in smaller tanks. Due to its shy nature, it should not be housed with boisterous or overly aggressive tank mates that could outcompete it for food.

This species spends most of its time near the substrate or hiding among rocks, emerging during feeding times. Its calm demeanor and unique appearance make it a fascinating addition to a peaceful reef tank.

Health and Common Issues

When properly cared for, the Fourmanoir's Perchlet is a hardy species. However, its shy nature can make it prone to stress, which may lead to health issues if not addressed. Providing a stable environment, a varied diet, and plenty of hiding spots can help reduce stress and promote longevity.

Look for active, alert individuals with vibrant coloration when purchasing. Avoid fish that appear lethargic or have visible signs of disease. Quarantining new additions is always recommended to prevent the introduction of parasites or illnesses into the main tank.

Habitat

The natural habitat of Plectranthias fourmanoiri includes deep reef slopes and rocky outcrops in the Indo-Pacific region. It is often found at depths ranging from 30 to 100 meters, where it lives among coral rubble and rocky crevices. Replicating this environment in captivity with plenty of live rock and shaded areas will help this species feel secure and exhibit natural behaviors.
