Coral Care Info Favia

Natural Habitat and Location in the Wild

Favia corals are found in the Indo-Pacific region, including Australia, Indonesia, the Philippines, Fiji, and the Great Barrier Reef. They thrive in a variety of reef environments, from shallow lagoons to deeper reef slopes, where they grow on rocky substrates in areas with moderate lighting and gentle water flow.

Why Choose Favia for Your Reef Tank?

• Hardy & Beginner-Friendly – Tolerates a range of water conditions.
• Unique Aesthetic – Forms rounded, encrusting, or dome-shaped colonies with intricate patterns.
• Moderate Growth Rate – Expands steadily under proper conditions.
• Photosynthetic but Benefits from Feeding – Gains energy from both light and supplemental feedings.

Optimal Water Parameters

Maintaining stable water conditions ensures the best health and coloration for Favia corals:

Regular water changes (10-15% weekly) help maintain stability and prevent nutrient imbalances.

Tank Size and Setup

• Minimum Tank Size: 20 gallons or larger.
• Placement: Prefers mid to lower areas of the tank.
• Substrate Considerations: Best placed on rockwork or sand, ensuring enough space for sweeper tentacles.

Lighting Requirements

Favia corals thrive under moderate lighting, which enhances their fluorescence while preventing bleaching.

• PAR Range: 80-150 PAR
• Lighting Type: LED, T5, or hybrid setups with blue-spectrum emphasis.
• Lighting Schedule: 8-10 hours per day, with gradual intensity transitions.

Water Flow and Circulation

• Moderate, indirect water flow ensures proper polyp expansion.
• Avoid strong, direct currents, which can cause tissue recession.
• Randomized flow patterns help prevent detritus buildup and enhance nutrient absorption.

Feeding and Nutrition

Favia corals benefit from both photosynthesis and direct feeding, absorbing nutrients through their polyps.

• Preferred Foods: Mysis shrimp, brine shrimp, reef roids, and amino acids.
• Feeding Frequency: 2-3 times per week enhances growth and coloration.
• Best Feeding Method: Target feeding at night when polyps extend.

Tank Mates and Compatibility

• Safe Companions: Clownfish, gobies, blennies, shrimp, and snails.
• Caution With: Other LPS corals—Favia has moderate sweeper tentacles that can sting nearby corals.
• Avoid: Aggressive fish like certain angelfish and butterflyfish, which may nip at polyps.

Growth Rate and Propagation

• Moderate growth rate, spreading as an encrusting or dome-shaped structure.
• Fragging Method: Use a bone cutter or bandsaw to create clean fragments for propagation.

Common Diseases and How to Prevent Them

• Brown Jelly Disease – A bacterial infection requiring iodine dips and improved water quality.
• Tissue Recession – Often caused by unstable parameters or excessive flow.
• Algae Overgrowth – Can smother the coral if excess nutrients are present.

Handling and Acclimation

• Drip acclimation is recommended to gradually adjust the coral to new water conditions.
• Minimize handling, as tissue damage can lead to infection.

Maintenance and Cleaning

• Perform weekly water changes (10-15%) to maintain water quality.
• Remove detritus buildup around the coral to prevent bacterial infections.

Signs of Stress and How to Address Them

• Shrunken or receding tissue – May indicate poor water quality, excessive flow, or aggression from nearby corals.
• Faded or bleached coloration – Reduce light intensity and increase feeding.
• Overgrowth on unwanted areas – Frag and relocate colonies to prevent excessive spread.

Troubleshooting Common Issues

• Bleaching – Caused by excessive light exposure; move to a lower-light area.
• Pest Infestation – Inspect regularly for flatworms, nudibranchs, or parasitic snails.
• Slow Growth – Increase target feeding and ensure stable alkalinity and calcium levels.
