• Minimum tank size: 120L+ (preferably 150L+ for pairs or anemone hosting)
• Adult size: ~16 cm (6 inches)

Sebae Clownfish (Amphiprion sebae) – A Bold and Hardy Anemonefish
The Sebae Clownfish is a stunning yet uncommon clownfish species that is often confused with Clarkii Clownfishdue to their similar coloration. Unlike the Clarkii, the Sebae Clownfish has a more distinctive black and yellow body with a curved white band. This species is hardy, active, and semi-aggressive, making it a good choice for aquarists who want a bold and striking clownfish.
Appearance and Coloration
Sebae Clownfish have a classic yet unique clownfish pattern:
• A dark brown to black body, contrasting sharply with its bright yellow tail and pectoral fins.
• Two bold white bands—one near the head and another in the midsection (often curved).
• A yellow snout, unlike Clarkii Clownfish, which often have a more uniform brown body.
• Females are larger and more dominant than males, as clownfish are protandrous hermaphrodites (all start as males and can become females if needed).
Sebae Clownfish can darken with age, with some adults appearing almost entirely black except for their white stripes and yellow tail.
Natural Habitat and Behaviour
Sebae Clownfish are found in the Indo-Pacific region, including India, Sri Lanka, and the Andaman Sea. In the wild, they:
• Host with anemones, especially Sebae Anemones (Heteractis crispa) and Carpet Anemones (Stichodactyla gigantea).
• Are territorial and aggressive toward intruders, particularly if they are defending an anemone.
• Live in pairs or small groups, forming a strict dominance hierarchy.
In captivity, they do not require an anemone, but they will still claim a rock formation, coral, or artificial structure as their home.
Tank Requirements and Water Parameters
Sebae Clownfish are resilient and adaptable, but they require a spacious and well-maintained environment.
• Minimum tank size: 120L+ (150L+ recommended for pairs or anemone hosting)
• Temperature: 24–27°C (75–81°F)
• pH: 8.1–8.4
• Salinity: 1.020–1.025
• Water movement: Moderate to strong
• Filtration: High-quality filtration and regular water changes are essential for maintaining water quality.
If keeping an anemone, ensure stable lighting and water parameters, as anemones require excellent conditions to thrive.
Diet and Feeding
Sebae Clownfish are omnivores, requiring a varied diet for health and color vibrancy.
Recommended foods include:
• High-quality marine pellets and flakes – Provides essential nutrients.
• Frozen mysis and brine shrimp – Adds variety and protein.
• Chopped seafood (shrimp, squid, or fish) – Occasional treats.
• Algae-based foods or spirulina – Supports digestion and immune function.
Feed 1-2 times per day, ensuring portions are small enough to prevent overfeeding and waste buildup.
Compatibility and Tank Mates
Sebae Clownfish are semi-aggressive, particularly when defending a territory or anemone. They can be more aggressive than Ocellaris or Percula Clownfish but less aggressive than Maroon Clownfish.
Best tank mates include:
✔ Semi-aggressive tank mates such as Dwarf Angelfish, Wrasses, and Tangs.
✔ Hardy fish that can handle minor aggression (such as Basslets, Gobies, and Dottybacks).
✔ Reef-safe invertebrates such as shrimp, snails, and crabs.
Avoid housing with:
❌ Other clownfish species, unless in an extremely large tank to prevent fighting.
❌ Timid fish (e.g., Firefish, small Blennies) that may be harassed.
❌ Overly aggressive fish (e.g., Large Triggerfish, aggressive Damselfish) that may stress them out.
If keeping a pair, introduce them at the same time to prevent territorial disputes.
Hosting Anemones
Sebae Clownfish are naturally drawn to anemones, though they will also host corals or rock formations if no anemone is available. They prefer:
• Sebae Anemone (Heteractis crispa)
• Carpet Anemone (Stichodactyla gigantea)
• Long Tentacle Anemone (Macrodactyla doreensis)
⚠ Important Notes:
• Anemones require strong lighting (LEDs, metal halides, or T5s) and stable water conditions.
• Clownfish do not need an anemone to thrive.
• Anemones should only be kept by experienced aquarists.
Health and Disease Considerations
Sebae Clownfish are hardy, but they can be prone to:
• Marine Ich (Cryptocaryon irritans) – Often triggered by stress or poor water quality. Quarantining new fish before introduction is recommended.
• Brooklynella (Clownfish Disease) – A parasite that affects clownfish, causing heavy mucus buildup and difficulty breathing.
• Bacterial infections – Typically caused by poor water conditions or injuries.
To maintain good health:
✔ Provide a varied diet rich in vitamins and marine algae.
✔ Ensure stable water parameters with regular maintenance.
✔ Quarantine new fish before adding them to the main tank.
Lifespan and Long-Term Care
With proper care, Sebae Clownfish can live up to 10-15 years in captivity. Their bold personality, long lifespan, and unique coloration make them a great choice for aquarists looking for a striking clownfish species.
Why Choose a Sebae Clownfish?
✔ Deep black and yellow coloration with bold white bands – Distinctive and visually appealing.
✔ Hardy and adaptable, making them great for intermediate aquarists.
✔ Can live long lives, up to 15 years in captivity.
✔ Will host anemones if available, but does not require one.
✔ More unique than the common Ocellaris or Percula Clownfish.
⚠ Important Considerations Before Buying a Sebae Clownfish:
🚫 Can be territorial – Best kept singly or in a bonded pair.
🚫 Defends its territory aggressively, especially when hosting an anemone.
🚫 Requires a moderate to large tank – Needs swimming space and shelter.
