Pseudanthias huchtii (Threadfin Anthias)

Overview

  • Native to the Western Pacific, frequently found around reef slopes and coral-rich areas.
  • Notable for its beautiful coloration, featuring a pinkish body, vibrant red-orange dorsal fins, and elongated thread-like fin rays in males.
  • A peaceful schooling species prized for its active swimming and stunning appearance.
  • Suitable for intermediate to advanced marine hobbyists due to specialized feeding and habitat requirements.

Feeding

  • Planktivorous; naturally feeds on zooplankton and small marine organisms.
  • Requires frequent feedings of high-quality foods, including mysis shrimp, brine shrimp, finely chopped seafood, and specialized planktonic preparations.
  • Multiple daily feedings are necessary to maintain optimal health and vibrant coloration.
  • Dietary variety and regular feeding schedule essential for long-term health.

Habitat

  • Prefers moderately sized to large aquariums (minimum 75 gallons) with plenty of open swimming spaces and structured live rock.
  • Stable, mature aquarium conditions with excellent water quality are crucial.
  • Include ample hiding places and reef structures to mimic their natural environment and reduce stress.
  • Moderate to strong water flow and efficient filtration are required to maintain ideal water conditions.

Fish Care

  • Optimal water temperature: 72-78°F (22-26°C).
  • Recommended pH level: 8.1-8.4; specific gravity: 1.020-1.025.
  • Sensitive to fluctuations in water parameters; consistent monitoring and careful maintenance necessary.
  • Regular observation for marine diseases is important; early treatment ensures optimal health.

Compatibility

  • Peaceful; ideally kept in groups with one male and several females to encourage natural social behaviors.
  • Reef-safe; compatible with corals and ornamental invertebrates.
  • Suitable tank mates include peaceful wrasses, gobies, dartfish, clownfish, and other non-aggressive reef-friendly species.
  • Avoid aggressive or overly territorial species to maintain a stress-free environment.

Aquarium Behavior

  • Highly active swimmers, often seen schooling in open areas above reef structures.
  • Peaceful demeanor, making them excellent additions to community reef aquariums.
  • Social species; best behaviors observed when kept in small schools.
  • Providing ample swimming space and compatible tank mates encourages natural behaviors and reduces stress.
