Black Darwin clownfish, also known as Amphiprion ocellaris, are a popular and iconic species of marine fish. These colourful fish are commonly kept in home aquariums, and with proper care, they can thrive and live for several years. Here are some basic tips on how to keep Black Darwin clownfish in your aquarium.

  1. Tank Size: Black Darwin clownfish are small fish, but they still require a sufficient amount of space to swim around. A minimum tank size of 20 gallons is recommended for a pair of clownfish. If you plan to keep more than two clownfish, you will need a larger tank.
  2. Water Quality: It's crucial to maintain excellent water quality in your aquarium. Clownfish are sensitive to changes in water parameters, so it's important to perform regular water changes to keep ammonia, nitrate, and nitrite levels in check. Additionally, make sure to monitor the pH, salinity, and temperature of the water regularly.
  3. Tank Setup: Black Darwin clownfish are reef-safe and can be kept in a reef tank. However, they do need some hiding spots in the tank, such as rocks or coral caves. Make sure to provide plenty of hiding places for your clownfish, especially if you have more than one in the tank.
  4. Diet: Clownfish are omnivores, and in the wild, they feed on algae, plankton, and small crustaceans. In captivity, they can be fed a variety of foods, including flakes, pellets, frozen foods, and live foods. It's important to provide a varied diet to ensure that your clownfish receive all the nutrients they need.
  5. Tank Mates: Black Darwin clownfish are generally peaceful fish and can be kept with other non-aggressive species. However, it's best to avoid keeping them with large or aggressive fish, as they may be bullied or become stressed.
  6. These Clownfish have a symbiotic relationship with Bubble Tip Anemone (Entacmaea quadricolor). These require a 100L system minimum, that is mature and settled. Clownfish can live without Anemones and will often host other corals that may offer the same kind of home for them such as a Toadstool or Pulsing Xenia.

In conclusion, Black Darwin clownfish are a beautiful and fascinating species of marine fish that can be a joy to keep in your home aquarium. By following these basic tips, you can ensure that your clownfish thrive and live a long, healthy life in your tank.
