Cirrhitichthys Aprinus - The Spotted Hawkfish

Cirrhitichthys Aprinus (The Spotted Hawkfish)

Overview

  • Native to the Indo-Pacific, commonly found in coral reefs, rocky ledges, and lagoons.
  • Identified by its reddish-pink body covered in dark spots, giving it a distinctive appearance.
  • A hardy and territorial species known for its perching behavior on rocks and corals.
  • Typically observed resting on elevated surfaces, watching for prey.
  • Best suited for aquariums with stable water conditions, live rock structures, and non-aggressive tankmates.

Feeding

  • Carnivorous, primarily feeding on small fish, crustaceans, and invertebrates in the wild.
  • Thrives on a diet of frozen mysis shrimp, brine shrimp, and finely chopped seafood.
  • Readily accepts high-quality pellet and flake foods formulated for carnivorous marine fish.
  • Should be fed multiple small meals per day to maintain energy levels and healthy digestion.
  • A varied diet with protein-rich foods enhances its coloration and overall vitality.

Habitat

  • Prefers reef environments with moderate water flow and plenty of rock structures.
  • Frequently seen resting on coral heads or rock formations, using its pectoral fins for support.
  • Aquarium setups should include live rock for natural hiding spots and perching areas.
  • Requires high-quality filtration and stable water parameters to prevent stress and disease.
  • Providing shaded areas alongside open swimming space helps mimic its natural environment.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C) to maintain overall health.
  • Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
  • Requires routine water changes and stable conditions to thrive in captivity.
  • Not fully reef-safe, as it may prey on small crustaceans and ornamental shrimp.
  • Providing structured live rock formations supports its natural perching behavior.

Compatibility

  • Semi-aggressive and may become territorial toward similarly sized fish.
  • Compatible with tangs, clownfish, larger wrasses, and other robust marine species.
  • Should not be housed with very small fish or invertebrates that may be viewed as prey.
  • Works best in tanks with defined territories to reduce competition.
  • Providing rock formations and multiple hiding areas minimizes aggression.

Aquarium Behavior

  • A stationary yet observant species that spends time perched on rocks and coral structures.
  • Frequently seen scanning its environment before making quick, darting movements to catch food.
  • More confident when provided with plenty of perching spots and structured rock formations.
  • Providing a mix of hiding areas and swimming space encourages natural behaviors.
  • Over time, it may recognize its caretaker and display curiosity, especially during feeding times.
