Resplendent Anthias (Pseudanthias pulcherrimus) – A Vibrant and Active Reef Fish
The Resplendent Anthias, also known as the Resplendent Goldie, is a stunning and lively species admired for its brilliant coloration and dynamic schooling behavior. With proper care, P. pulcherrimus can be a captivating additionto a well-maintained reef aquarium.
Appearance and Coloration
The Resplendent Anthias is easily recognizable due to its:
• Orange to pink body, with a yellow face and caudal fin.
• Males developing iridescent blue pelvic fins edged in red.
• Females exhibiting a more subdued coloration compared to males.
This striking appearance makes the Resplendent Anthias a sought-after species for reef enthusiasts.
Natural Habitat and Behavior
Native to the western Indian Ocean, including regions like the Maldives and Mauritius, Resplendent Anthias inhabit:
• Coral reefs at depths ranging from 10 to 40 meters.
• Small aggregations, swimming actively in the water column.
• Haremic social structures, with one dominant male and multiple females.
In captivity, they thrive when provided with ample swimming space and structured environments that mimic their natural habitat.
Tank Requirements and Water Parameters
Due to their active nature, Resplendent Anthias require a well-structured aquarium with plenty of swimming space and hiding spots.
• Minimum tank size: 265L+ (70 gallons) for a single individual; larger tanks (380L+) recommended for harems.
• Temperature: 22–25.5°C (72–78°F)
• pH: 8.1–8.4
• Salinity: 1.020–1.025
• Water movement: Moderate to strong, simulating natural reef currents.
• Aquascaping: Provide ample live rock formations, with caves and ledges for security.
⚠ Ensure the aquarium has a tight-fitting lid, as Resplendent Anthias are known jumpers.
Diet and Feeding
Resplendent Anthias are planktivores, requiring frequent small feedings throughout the day. Their ideal diet includes:
• Frozen mysis and brine shrimp – Essential protein sources.
• Enriched frozen plankton – Helps mimic their natural diet.
• High-quality marine pellets and flakes – Supplemented with vitamins and color-enhancers.
• Live foods (copepods, amphipods, rotifers) – Beneficial, especially during acclimation.
Feeding frequency: At least 2–3 times per day to maintain their energy levels and vibrant coloration.
Compatibility and Tank Mates
Resplendent Anthias are peaceful fish, making them suitable for community reef tanks.
✔ Compatible with:
• Other peaceful, reef-safe fish, such as Clownfish, Wrasses, Firefish, and Blennies.
• Non-aggressive tank mates, as they can be outcompeted for food by faster fish.
• Reef-safe invertebrates, such as shrimp, snails, and crabs.
❌ Avoid housing with:
• Large, aggressive fish, such as Groupers, Triggerfish, or large Dottybacks.
• Fast-moving, aggressive feeders, which may stress them and prevent proper feeding.
• Overly dominant anthias species, which may cause territorial issues.
⚠ If keeping multiple Resplendent Anthias, introduce them simultaneously to establish a stable hierarchy.
Behavior and Social Structure
Resplendent Anthias:
• Prefer schooling in groups, rather than hiding.
• Exhibit natural dominance hierarchies, where the largest female may transition to male if the dominant male is lost.
Their energetic swimming and social interactions make them a fascinating addition to larger reef tanks.
Health and Disease Considerations
Resplendent Anthias are somewhat delicate and can be vulnerable to:
• Malnutrition, if not fed frequently enough.
• Marine Ich (Cryptocaryon irritans), particularly when stressed.
• Bacterial infections, usually due to poor water conditions.
To keep them healthy:
✔ Feed multiple times per day to prevent starvation.
✔ Provide plenty of swimming space to reduce stress.
✔ Maintain stable water conditions with excellent filtration and regular water changes.
Lifespan and Long-Term Care
With proper care, Resplendent Anthias can live up to 5–7 years in captivity. Their stunning coloration, peaceful nature, and schooling behavior make them an excellent choice for well-maintained reef aquariums.
Why Choose a Resplendent Anthias?
✔ Visually stunning, with a beautiful blend of orange, pink, and yellow hues.
✔ Active and social, adding energy and movement to reef tanks.
✔ Reef-safe, with no risk to corals or invertebrates.
✔ Fascinating social structure, making them interesting to observe in groups.
