Arothron Meleagris - The Guineafowl Pufferfish

Arothron Meleagris (The Guineafowl Pufferfish)

Overview

  • Found in tropical and subtropical waters of the Indo-Pacific and Eastern Pacific regions.
  • Recognized for its two distinct color morphs: a dark body covered in small white spots or a golden-yellow variation.
  • A large, slow-moving species that inflates when threatened to deter predators.
  • Highly valued in marine aquariums due to its unique appearance, intelligence, and interactive nature.
  • Requires a spacious and well-maintained aquarium with plenty of swimming room and rock formations.

Feeding

  • Omnivorous, feeding on small crustaceans, mollusks, coral, and algae in the wild.
  • Readily accepts a diet of frozen shrimp, squid, clams, and high-quality marine pellets.
  • Hard-shelled foods such as snails and crabs are necessary to prevent overgrown teeth.
  • Requires multiple feedings per day to maintain optimal health and energy levels.
  • A well-balanced diet promotes vibrant coloration and longevity.

Habitat

  • Typically found in coral reef environments, rocky coastlines, and sandy lagoons.
  • Prefers stable water conditions with moderate water movement.
  • Aquariums should include live rock formations, caves, and a sandy substrate for foraging.
  • Thrives in a well-established marine tank with ample swimming space.
  • Providing a structured environment with hiding areas helps reduce stress and encourage natural behavior.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C) to maintain immune function.
  • Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
  • Requires a high-performance filtration system to manage waste effectively.
  • Regular water changes and testing are necessary to maintain stable water parameters.
  • Providing a calm, stress-free environment helps prevent disease and promotes overall well-being.

Compatibility

  • Semi-aggressive; should be housed with similarly sized, robust fish.
  • Compatible with larger species such as tangs, angelfish, and certain wrasses.
  • Not reef-safe, as it may nip at coral polyps and consume small invertebrates.
  • Should not be kept with small, delicate fish or slow-moving tank mates.
  • Providing a well-structured environment minimizes aggression and encourages positive interactions.

Aquarium Behavior

  • An intelligent and curious species that explores its surroundings frequently.
  • Uses its strong teeth to crush shells and scrape algae from rocks and surfaces.
  • Capable of inflating when threatened, a defense mechanism that should not be provoked.
  • Providing enrichment such as caves and open swimming areas supports natural behaviors.
  • Recognizes caretakers over time and often becomes highly interactive.
