Resplendent Anthias (Pseudanthias pulcherrimus)

Overview

The Resplendent Anthias (Pseudanthias pulcherrimus) is a small planktivorous anthias species originating from the Red Sea and northern Indian Ocean. It displays a reddish-orange body with pink highlights and yellow fins accented by purple edging. This species is well-suited for reef aquariums due to its peaceful behavior and midwater swimming habits.

Key Features

• Scientific Name: Pseudanthias pulcherrimus

• Common Names: Resplendent Anthias, Tierra Anthias, Elegant Anthias

• Adult Size: 3–4 inches

• Temperament: Peaceful, schooling

• Reef Safe: Yes

• Diet: Planktivore (frequent small feedings)

Natural Habitat & Behavior

In the wild, Resplendent Anthias inhabit coral-rich outer reef slopes, swimming in small groups above substrate while relying on rockwork for shelter. Their midwater orientation and group dynamics translate well into captive systems when given adequate space and stable conditions.

Aquarium Requirements

• Minimum Tank Size: 75 gallons for a small group

• Aquascape: Rock structures with caves and shaded areas for refuge; open swimming space for midwater activity

• Water Flow: Moderate, simulating natural reef currents

Water Parameters

• pH: 8.1–8.4

• Salinity: 1.020–1.025

• Temperature: 75–82°F (24–28°C)

• Flow: Moderate

Diet & Feeding

Resplendent Anthias require frequent, small feedings. Their diet should include:

• High-quality micro-pellets designed for planktivores

• Frozen Mysis shrimp, enriched brine shrimp, copepods, and other small crustaceans

• Occasional spirulina-based or algae-enriched foods for nutritional variety

Vitamin-enriched foods help maintain coloration and overall health. Systems with a refugium may support supplemental natural zooplankton populations.

Compatibility

This species is peaceful and compatible with many reef-safe fish, including:

• Clownfish (Amphiprion spp.)

• Firefish (Nemateleotris spp.)

• Royal Gramma (Gramma loreto)

• Select dwarf angelfish (Centropyge spp.)

• Fairy Wrasses (Cirrhilabrus spp.)

Resplendent Anthias may be kept singly, but small groups exhibit more natural behavior.

Sexual Dimorphism & Coloration

Males display more intense pink, orange, and purple pigmentation, while females and juveniles show subtler yellow-orange tones. Color intensifies with maturity and stable nutrition.
