Siganus Corallinus - The Coral Rabbitfish

Siganus Corallinus (The Coral Rabbitfish)

Native to the Indo-Pacific, commonly found in shallow lagoons, coral reefs, and seagrass beds.
Recognized for its vibrant yellow coloration and streamlined body, making it a visually appealing addition to aquariums.
A peaceful and social species that thrives in well-structured reef environments.
Known for its venomous dorsal spines, which can deliver a painful sting if threatened.
Best suited for aquariums with ample swimming space, live rock formations, and stable water conditions.

Herbivorous, primarily feeding on algae, seagrass, and marine plant material in the wild.
Thrives on a diet of seaweed, spirulina, algae-based pellets, and frozen herbivore preparations.
Actively grazes on nuisance algae, making it a beneficial addition to reef tanks.
Should be fed multiple times daily to maintain energy levels and support healthy digestion.
A varied diet rich in plant-based nutrients enhances coloration and supports a strong immune system.

Prefers reef-associated environments with moderate water currents and abundant plant life.
Frequently seen foraging along coral reefs and seagrass meadows for algae growth.
Aquarium setups should include live rock to provide natural grazing areas and hiding spots.
Requires stable water parameters and strong filtration to maintain optimal water quality.
Providing a spacious environment encourages active swimming and natural foraging behaviors.

Optimal water temperature: 74-80°F (23-27°C) to support metabolic activity.
Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
Requires regular water changes and consistent maintenance to prevent algae overgrowth.
Reef-safe but may nip at soft corals if not provided with sufficient plant-based food sources.
Providing an enriched diet and structured habitat ensures a stress-free and active fish.

Peaceful and well-suited for community reef tanks with other non-aggressive species.
Compatible with tangs, wrasses, angelfish, and other herbivorous or semi-aggressive fish.
Should not be housed with overly aggressive species that may cause stress.
Best kept in environments where it has access to ample grazing surfaces.
Providing multiple rock formations and swimming space ensures a balanced tank dynamic.

An active swimmer that constantly forages for algae and plant matter.
Frequently seen exploring rock formations and interacting with tankmates.
More confident in a well-established aquarium with stable environmental conditions.
Providing a structured environment with hiding areas encourages natural behaviors.
Over time, it may become accustomed to its caretaker and actively engage during feeding sessions.
