Understanding Hammer Coral Care:

Hammer coral, scientifically known as euphyllia ancora, is a fascinating species of stony coral that is relatively easy to care for. If you’re planning on adding this coral to your aquarium, it’s essential to understand its basic care requirements. In this section, we will discuss the key points to keep in mind when it comes to hammer coral care.

Water Parameters:

Maintaining the right water parameters is crucial for the health and longevity of your hammer coral.

  • Temperature: hammer coral thrives in temperatures between 75-80 degrees fahrenheit.
  • Salinity: it’s essential to maintain a consistent salinity level of 1. 025.
  • Ph: a ph level of 8. 0-8. 4 is optimal for hammer coral.
  • Alkalinity: hammer coral prefers alkalinity levels of 8-12 dkh.
  • Calcium and magnesium: these elements are essential for the growth and development of hammer coral. Calcium levels should be between 400-450 ppm, and magnesium levels should be between 1250-1350 ppm.

Lighting Requirements:

Lighting is a crucial aspect of hammer coral care, as they rely on light for photosynthesis.

  • Light intensity: hammer coral thrives in moderate to high lighting conditions. Intensity levels should be between 150-250 par.
  • Spectral requirements: hammer coral requires a spectrum of light that includes both blue and white light.

Feeding Habits:

While hammer coral can obtain the majority of their nutrients through photosynthesis, they also require additional food sources to thrive.

  • Supplemental feeding: feed your hammer coral a combination of phytoplankton and zooplankton twice a week.
  • Target feeding: directly target your coral with food using a turkey baster or small pipette.
  • Don’t overfeed: overfeeding can lead to poor water quality and harm your coral.

Providing the right water parameters, adequate lighting, and proper feeding habits are essential for the health and growth of your hammer coral. Keep these points in mind, and your hammer coral will be a beautiful addition to your aquarium for years to come.

Hammer Coral Placement:

Hammer coral placement:

After you have selected your hammer coral, the next step is deciding where to place it in your aquarium. Hammer corals are not picky about where they reside, but they still require the correct conditions to flourish.

Selecting The Right Location:

When choosing the placement of your hammer coral, there are a few things to consider.

  • Flow: hammer corals prefer moderate flow. If the flow is too strong, the coral will struggle, and if the flow is too weak, the coral won’t get the nutrients it needs to grow correctly.
  • Lighting: hammer corals need moderate to high lighting to thrive. If the lighting is too low, the coral will not grow, and if the lighting is too high, it will lead to bleaching and eventually, death.
  • Water parameters: hammer corals prefer a stable water temperature between 75 and 79 degrees fahrenheit. The ph level should be between 8. 1 and 8. 4. Keep an eye on alkalinity and calcium levels to ensure they stay in a healthy range.

Compatible Tank Mates:

Hammer corals have long sweeper tentacles, which can create territorial issues if placed too close to other corals. It’s important to place hammer corals away from other corals to avoid any issues.

  • Clownfish: they will host the coral and keep it clean.
  • Blennies: they won’t harm the coral and help to maintain good tank hygiene.
  • Gobies: they will keep sand stirred and bring nutrients to the coral.


When it comes to aquascaping, place your hammer coral on its own rock or on the sand bed. Try to space each hammer coral at least six inches apart to avoid any territorial disputes.

When selecting a rock for your hammer coral, choose a flat surface that won’t tip over. The hammer coral will attach its base to the rock, so it’s crucial to choose a stable option.

Pro tip: position your hammer coral to show off its unique and beautiful tentacles.

Correct placement of your hammer coral is crucial to its well-being. Consider the flow, lighting, and water parameters. Ensure there are no territorial issues with other corals and aquascape appropriately. Follow these guidelines to create a suitable environment for your hammer coral to thrive and grow.

Common Issues And Solutions:

Hammer coral is a gorgeous and challenging species to keep, but like many other corals, it can suffer from common issues.

Diseases And Pests:

  • brown jelly syndrome: this is a bacterial infection characterized by a brown sludge that covers and destroys the coral’s tissue. Remove the infected coral from the tank to avoid the spread of the disease. Dip the affected coral in a coral dip solution and then quarantine it for a few weeks.
  • white band disease: this disease causes the coral tissue to problematize and fall off. Unfortunately, there is no known cure for this disease yet, so the infected coral should be removed from the tank and destroyed.
  • red bugs: these small pests feed on the coral’s tissue and are almost invisible to the naked eye. You may notice small white spots or a dust-like substance on the coral’s surface. Remove the infected coral and dip it in a coral dip solution. The other corals in the tank may also need to be treated.
  • flatworms: these flat, worm-like pests are on the coral’s surface and can cause tissue necrosis. Quarantine the affected coral and rinse it in freshwater to remove them physically. Use a coral dip or raise the specific gravity of the tank to kill the remaining flatworms.

Coral Tantrums:

  • bleaching: this phenomenon happens when the coral loses its symbiotic algae, called zooxanthellae, which provide the coral with its food and color. Monitor the water parameters such as temperature, salinity, and lighting to ensure they are stable and correct.
  • algae overgrowth: algae can grow over the coral and compete for space and nutrients. To prevent this from happening, keep the tank’s nutrient levels in balance, and limit the light and feeding regime. You can also use algae-eating creatures such as snails, hermit crabs, and tangs to help control the algae growth.

Taking proper care of your hammer coral is key, but knowing how to deal with common issues and coral tantrums is vital to their survival. By following the solutions mentioned above, you can maintain a healthy and happy environment for your corals to thrive in.
