At SaltwaterReefCo, we love helping our clients create thriving aquatic environments, and few saltwater fish bring as much playful personality and vibrant color to a reef tank as the Clownfish. These charismatic marine fish, primarily from the genus Amphiprion, are adored by aquarists for their unique symbiotic relationship with anemones, their iconic orange and white stripes, and their lively demeanor.
While generally considered one of the hardier marine fish to care for, Clownfish have specific needs that must be met to ensure they flourish. Their territorial nature and need for a stable environment require a well-maintained system. Here's what you need to know about keeping these magnificent creatures:
Tank Requirements
Clownfish are active swimmers that spend much of their time hovering in and around their chosen host, whether it be an anemone, coral, or a piece of rockwork.
Minimum Tank Size: For a bonded pair of Clownfish, a minimum of a 20-gallon aquarium is recommended. Larger tanks are always preferred to provide more stable water parameters and room for other tank mates.
For a Pair: Clownfish should be kept in a pair. They are sequentially hermaphroditic, with the dominant fish becoming female and the smaller, submissive fish remaining male.
Aquascaping: Provide ample live rock with plenty of caves and crevices. While not essential, providing a suitable host anemone or a host coral (such as a torch coral or bubble coral) can be a fascinating display of their natural behavior.
Filtration & Flow: Robust filtration (sump, protein skimmer, refugium) is crucial for maintaining pristine water quality. Clownfish appreciate moderate, gentle water flow, as strong, turbulent currents can be stressful for them.
Water Parameters
Clownfish are marine fish and demand stable, high-quality saltwater conditions, typical of a healthy reef tank.
Temperature: Maintain a consistent water temperature between 74-80°F (23-27°C).
pH: A stable pH range of 8.1 to 8.4 is ideal.
Water Changes: Regular partial water changes (10-20% weekly or bi-weekly) are essential for replenishing trace elements and preventing nutrient buildup.
Diet and Feeding
Clownfish are omnivores and are not typically fussy eaters. They should be fed a varied diet to ensure proper nutrition.
Varied Diet: Offer a diverse diet of high-quality marine flake and pellet foods, supplemented with frozen foods like mysis shrimp, brine shrimp, and finely chopped seafood.
Feeding Frequency: Feeding small amounts two to three times daily is generally sufficient, only what they can consume in 1-2 minutes.
Tank Mates
Clownfish are generally peaceful fish, but they can be territorial, especially if a host anemone is present. They will aggressively defend their chosen home.
Good Tank Mates: Other peaceful, non-aggressive reef fish. Good options include:
- Cardinalfish
- Gobies
- Blennies
- Chromis damselfish
- Dartfish
- Wrasses
- Dwarf Angelfish
Avoid:
- Large Predatory Fish: Large predatory fish that could view Clownfish as food.
- Other Clownfish: Avoid keeping different species of Clownfish together unless you have a very large tank, as they can be highly aggressive towards each other.
- Fin-Nippers: Some species of triggerfish or larger wrasses may nip at their fins.
Common Health Concerns
While generally hardy, Clownfish can be susceptible to common saltwater diseases if water quality is poor or they are stressed.
Ich (Cryptocaryon irritans): A common parasitic infection causing small white spots.
Marine Velvet (Amyloodinium ocellatum): A highly contagious parasitic infection, often appearing as a dusty coating.
Stress: Poor water quality, inappropriate tank mates, or an unstable environment can lead to stress, making them susceptible to other diseases.
Prevention is key! Always quarantine new fish for 4-6 weeks, maintain pristine water conditions, and provide a nutritious diet. If you notice any signs of illness, prompt diagnosis and treatment are crucial.
