Cephalopholis Miniata - The Coral Grouper

Cephalopholis Miniata (The Coral Grouper)

Overview

  • Native to the Indo-Pacific, frequently found in coral reefs, rocky outcrops, and deep reef slopes.
  • Recognized for its bright red to orange body covered in numerous small, iridescent blue spots.
  • A predatory species known for its ambush hunting techniques and territorial behavior.
  • Can grow to a considerable size and requires a spacious tank with ample swimming and hiding areas.
  • Best suited for an established marine aquarium with rock structures and tankmates of similar size and temperament.

Feeding

  • Carnivorous, primarily preying on fish, crustaceans, and other small marine animals.
  • Accepts high-quality marine pellets, frozen shrimp, squid, and live feeder fish.
  • Requires a protein-rich diet to maintain its striking coloration and overall health.
  • Should be fed multiple times a day to satisfy its predatory nature and reduce aggression.
  • Prefers live prey but can adapt to frozen and prepared foods over time.

Habitat

  • Typically found in rocky and coral reef environments where it can ambush prey.
  • Prefers stable water conditions with moderate to strong water flow.
  • Aquarium setups should include caves, overhangs, and crevices for hiding and territorial establishment.
  • Requires a well-maintained marine tank to prevent stress-related health issues.
  • Providing shaded areas and well-defined territories helps reduce aggression and stress.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C) for maintaining metabolic health.
  • Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
  • Requires powerful filtration and routine water changes to control waste buildup.
  • Needs an aquarium large enough to accommodate its territorial behavior and predatory nature.
  • Providing live rock formations enhances its environment and supports natural behaviors.

Compatibility

  • Highly territorial and best housed with larger, robust fish species.
  • Compatible with other large groupers, tangs, and aggressive marine fish.
  • Not reef-safe, as it will prey on smaller fish and invertebrates.
  • Should not be housed with timid or smaller fish that may become prey.
  • Providing ample swimming space and rock structures helps mitigate aggressive tendencies.

Aquarium Behavior

  • A dominant species that establishes a specific territory within the tank.
  • Often found lurking near rock formations, waiting to ambush prey.
  • Can exhibit aggressive behavior towards tankmates if its space is encroached upon.
  • Providing a well-structured tank with caves and hiding spots supports its natural instincts.
  • Over time, it may become more interactive with its caretaker, particularly around feeding times.
