Arothron Manilensis (The Narrow-Lined Pufferfish)

Overview

• Native to the Indo-Pacific region, commonly found in shallow coastal waters, seagrass beds, and sandy bottoms.
• Distinguished by its elongated body shape and fine, dark lines running along its pale-colored skin.
• A relatively peaceful species that can become territorial in confined spaces.
• Has the ability to inflate itself as a defense mechanism when feeling threatened.
• A hardy species well-suited for marine aquariums with ample space and hiding areas.

Feeding

• Omnivorous diet, feeding on small crustaceans, mollusks, algae, and detritus in the wild.
• Accepts a variety of aquarium foods, including frozen shrimp, squid, marine pellets, and algae-based diets.
• Requires hard-shelled foods such as snails or clams to maintain proper tooth growth.
• Multiple small feedings per day are recommended to support its active metabolism.
• A well-balanced diet enhances coloration and ensures a strong immune system.

Habitat

• Commonly found in sandy lagoons, seagrass meadows, and reef-associated environments.
• Prefers stable water conditions with moderate flow and plenty of open swimming space.
• Aquariums should feature a sandy substrate and ample hiding spots to mimic their natural habitat.
• Best suited for well-established marine tanks with proper rock formations.
• Providing a variety of textures and natural decor encourages natural exploration and foraging behaviors.

Fish Care

• Optimal water temperature: 74-80°F (23-27°C) for maintaining a healthy immune system.
• pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
• Requires high water quality with an efficient filtration system to prevent ammonia and nitrate buildup.
• Regular water changes and monitoring of water parameters are necessary for long-term health.
• Providing a calm and stress-free environment ensures better adaptation to captivity.

Compatibility

• Generally peaceful but may show territorial tendencies, especially in smaller tanks.
• Compatible with larger, non-aggressive fish such as tangs, angelfish, and wrasses.
• Not recommended for reef tanks, as it may nip at coral and consume small invertebrates.
• Should not be housed with delicate or slow-moving fish that may be outcompeted for food.
• Providing sufficient space and a structured environment helps reduce stress and aggression.

Aquarium Behavior

• An inquisitive species, often seen exploring its surroundings and interacting with objects in the tank.
• Uses its strong, beak-like teeth to crush shells and scrape algae from surfaces.
• Capable of inflating when feeling threatened, though this behavior should not be triggered intentionally.
• Providing hiding spaces and live rock structures encourages natural foraging behaviors.
• Over time, it can recognize caretakers and exhibit engaging, personable interactions.
