The Midnight Clownfish boasts a stunning appearance characterized by its jet-black body adorned with three bright white stripes. These stripes typically run horizontally across the fish’s body, providing a striking contrast against the dark background. The fins of the Midnight Clownfish also feature a vivid orange hue, adding to its allure.

Average Size

Like their Percula Clownfish counterparts, Midnight Clownfish are relatively small in size. On average, they grow to about 3 inches (7.6 cm) in length, making them suitable for smaller aquarium setups.


With proper care, Midnight Clownfish can live for an average of 6 to 10 years in captivity. Factors such as water quality, diet, and tank mates play significant roles in determining their lifespan.

Habitat and Aquarium Setup

Habitat and Natural Environment

In the wild, Midnight Clownfish are found in the warm waters of the Indo-Pacific region, particularly around the coral reefs of Australia and Papua New Guinea. They inhabit the sheltered areas of reef crevices or anemones, forming symbiotic relationships with certain species of sea anemones for protection.

Tank Size

For a single pair of Midnight Clownfish, a tank size of at least 20 gallons is recommended. However, if you plan to keep multiple pairs or include other tank mates, a larger tank of 30 gallons or more would be suitable to accommodate their territorial nature.

Water Parameters

Maintaining stable water parameters is crucial for the health and well-being of Midnight Clownfish. Aim for the following water conditions:

  • Temperature: 75-82°F (24-28°C)
  • pH: 8.0-8.4
  • Salinity: 1.020-1.025
  • Ammonia, nitrite, and nitrate levels should remain at undetectable levels.

Setting Up the Aquarium for Midnight Clownfish

When setting up the aquarium for Midnight Clownfish, mimic their natural reef habitat by incorporating live rock formations and plenty of hiding spots. Additionally, consider adding a host anemone for the Clownfish to form a symbiotic bond, though this is not mandatory for their well-being.

Aquarium Decor and Hiding Spots

Provide ample hiding spots and sheltered areas within the aquarium using live rock formations, PVC pipes, or artificial caves. These hiding spots are essential for Midnight Clownfish to retreat to when they feel threatened or stressed.

Filtration and Water Flow

Adequate filtration is crucial for maintaining water quality in the aquarium. A combination of mechanical, biological, and chemical filtration systems can help keep the water clean and free from harmful pollutants. Additionally, ensure sufficient water flow within the tank to mimic the natural currents found in reef environments.

Care and Maintenance

Midnight Clownfish Diseases

Common Possible Diseases

Midnight Clownfish are generally hardy fish, but they are still susceptible to certain diseases if proper care is not taken. Common ailments that may affect them include:

  • Ich (white spot disease)
  • Marine velvet
  • Fin rot

Regular observation of your Clownfish for any signs of illness, along with maintaining optimal water quality, can help prevent the onset of these diseases.

Food & Diet

In the wild, Midnight Clownfish are omnivores, feeding on a diet consisting of “algae, small crustaceans, and zooplankton.” In captivity, they readily accept a variety of commercially available fish foods, including pellets, flakes, and frozen or live foods such as brine shrimp and mysis shrimp.

Temperament & Behavior

Midnight Clownfish are known for their bold and active behavior. They are relatively peaceful fish but can exhibit territorial aggression, especially towards other Clownfish species. When kept in pairs or small groups, they form hierarchical structures with one dominant female and one smaller male.

Tank Mates

When selecting tank mates for Midnight Clownfish, choose species that are compatible with their temperament and environmental requirements. Avoid keeping them with overly aggressive or large predatory fish that may intimidate or harm them. Suitable tank mates include other peaceful reef fish such as gobies, blennies, and certain species of damselfish.

Cleaning and Maintenance

Regular cleaning and maintenance are essential for keeping the aquarium environment healthy and conducive to the well-being of Midnight Clownfish. Perform routine water changes to remove accumulated debris and replenish essential nutrients. Additionally, clean the filter media regularly to prevent clogging and maintain optimal filtration efficiency.

By adhering to these care guidelines and providing a suitable environment, you can ensure that your Midnight Clownfish thrive and display their stunning beauty for years to come.
