Building your habitat

  • Water health - Provide proper filtration to ensure optimal water quality to help maintain health. Low to moderate water circulation, based on species, should be provided to mimic water currents found in the clownfish’s natural habitat. Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to the health of aquatic life. If you are unsure of your water quality, bring a sample to Petco for free testing. The addition of a protein skimmer can aid with maintaining great water quality and high dissolved oxygen levels. An aquatic heater should be used to stabilize water temperature, ensuring it does not fluctuate more than +/-2 degrees in a 24-hour period. The specific gravity should remain stable. Do not allow specific gravity to fluctuate more than +/-0.001 in a 24-hour period
  • Décor - Provide rock and décor for hiding places and plenty of room for movement

Things to remember when feeding your clownfish:

Clownfish care

  • Water care - Maintaining great water quality with regular water changes and adequate filtration is important to help keep your clownfish healthy
    • Daily: Check filter, water temperature and other equipment
    • Weekly: Test water quality at least once a week
    • Weekly to monthly: Change 10 to 25 percent of the total volume of water every two to four weeks, or as needed; change filter media monthly
