Pseudanthias smithvanizi - Princess Anthias

Pseudanthias smithvanizi (Princess Anthias)

Overview

  • Native to the Indo-Pacific region, typically found in outer reef slopes and drop-offs.
  • Distinguished by its vivid pink and purple hues with subtle yellow highlights, especially in males.
  • A peaceful, schooling species often seen swimming in the water column above coral formations.
  • Best suited for intermediate to advanced aquarists due to its dietary and environmental needs.

Feeding

  • Planktivorous; primarily feeds on zooplankton and other small marine organisms.
  • In captivity, thrives on a varied diet of mysis shrimp, brine shrimp, finely chopped seafood, and specialized planktonic foods.
  • Feed small amounts multiple times daily to replicate natural feeding behavior.
  • Consistent, high-quality feeding is essential for health and vibrant coloration.

Habitat

  • Requires a mature, well-established aquarium (minimum 70 gallons) with excellent water quality and circulation.
  • Open swimming space is important, along with structured live rock for refuge.
  • Prefers subdued lighting and low-stress environments to thrive.
  • Hiding places help reduce stress and support natural schooling behavior.

Fish Care

  • Optimal water temperature: 72-78°F (22-26°C).
  • pH level: 8.1-8.4, with a specific gravity of 1.020-1.025.
  • Requires stable water parameters; fluctuations can lead to stress or health issues.
  • High water quality maintained through regular testing and water changes is vital.

Compatibility

  • Peaceful and best kept in small groups with one male and multiple females.
  • Compatible with other peaceful reef-safe species; avoid aggressive tank mates.
  • Well-suited for reef aquariums, safe with corals and most invertebrates.
  • May be shy around overly active or aggressive species, especially in smaller tanks.

Aquarium Behavior

  • Schooling fish that prefers to swim in mid-water, especially in groups.
  • Can be shy at first, but will become more confident in a stable, well-maintained environment.
  • Thrives with plenty of space to swim and shelter to retreat to when needed.
  • Displays bright coloration and natural behavior under ideal conditions.
