Feeding Corals: Best Practices

While many corals obtain energy through their symbiotic zooxanthellae, supplementing their diet with particulate or dissolved food enhances their growth and coloration.

Types of Coral Food

1. Particulate Foods

• Examples: Brine shrimp, mysis shrimp, finely chopped seafood, coral food pellets.
• Usage: Directly target corals by feeding during lighting periods when photosynthesis is active.
• Tips:
  • Use feeding tongs or turkey basters to place food close to the coral polyps.
  • Offer small amounts to prevent excess nutrients and avoid stressing the corals.

2. Dissolved Foods

• Examples: Liquid phytoplankton, zooplankton supplements, amino acid blends.
• Usage: Dose into the water column during or shortly after lighting periods.
• Tips:
  • Follow manufacturer dosing instructions to avoid overfeeding.
  • Observe coral responses and adjust dosing accordingly.

Feeding Frequency

• Hard Corals (SPS and LPS): Feed 1-2 times per week.
• Soft Corals: Feed 2-3 times per week.
• Zoanthids and Mushrooms: Feed as needed, typically 1-2 times per week.

Feeding Tips

• Observe Coral Behavior: Look for signs of feeding, such as tentacle movements, to gauge coral interest.
• Avoid Overfeeding: Excess food can lead to nutrient spikes and algae growth. Start with small quantities and increase as needed.
• Use Quality Foods: Choose high-quality coral foods that provide essential nutrients without additives that could harm corals.

Best Practices for Coral Care

Implementing best practices in coral care ensures a thriving and balanced reef aquarium. Here are essential strategies to maintain healthy corals:
