Coral Care Info Sinularia Leather

Sinularia, commonly known as Leather Coral or Finger Leather Coral, is a soft coral prized for its tree-like branching structure and incredible hardiness. It comes in a variety of colors, including green, yellow, tan, pink, and brown, and can grow into large, flowing colonies that add movement and texture to a reef tank.
Sinularia corals are easy to care for and fast-growing, making them a fantastic choice for beginner and experienced reef keepers alike. They can thrive in a wide range of conditions, tolerate minor water fluctuations, and even help reduce toxins in the aquarium. However, they release chemical compounds (allelopathy) that can inhibit the growth of nearby corals, so careful placement and regular water changes are recommended.
Natural Habitat and Location in the Wild
Sinularia corals are found in the Indo-Pacific region, particularly in Australia, Indonesia, Fiji, the Red Sea, and the Great Barrier Reef. They thrive in shallow reef slopes, lagoons, and reef flats, where they attach to rocky substrates and experience moderate to strong water flow.
Why Choose Sinularia for Your Reef Tank?
- Extremely Hardy & Beginner-Friendly – Tolerates a wide range of water conditions.
- Fast-Growing & Spreading – Quickly forms large, tree-like structures.
- Natural Toxin Absorption – Helps remove some toxins from the water.
- Resilient & Adaptive – Can survive in various lighting and flow conditions.
Optimal Water Parameters
Maintaining stable water conditions ensures the best health and coloration for Sinularia:
Parameter | Ideal Range |
---|---|
Temperature | 76-80°F (24-27°C) |
Salinity | 1.024-1.026 SG |
pH | 8.1-8.4 |
Alkalinity | 8-10 dKH |
Calcium | 400-450 ppm |
Magnesium | 1250-1350 ppm |
Nitrate | 5-15 ppm |
Phosphate | 0.03-0.1 ppm |
Weekly water changes (10-15%) help dilute toxins and maintain stability.
Tank Size and Setup
- Minimum Tank Size: 20 gallons or larger.
- Placement: Prefers mid to upper areas of the tank, ensuring room for vertical growth.
- Substrate Considerations: Best attached to live rock, as it will naturally expand and encrust surfaces.
Lighting Requirements
Sinularia corals thrive under moderate to high lighting, helping to sustain their growth and coloration.
- PAR Range: 100-250 PAR
- Lighting Type: LED, T5, or hybrid setups with a full-spectrum blue-white balance.
- Lighting Schedule: 8-10 hours per day, with gradual intensity transitions.
Water Flow and Circulation
- Moderate to strong water flow ensures proper polyp expansion and waste removal.
- Avoid stagnant areas, as poor circulation can lead to bacterial infections.
- Randomized flow patterns help mimic natural reef conditions.
Feeding and Nutrition
Sinularia primarily relies on photosynthesis but benefits from occasional supplemental feeding to boost growth.
- Preferred Foods: Phytoplankton, zooplankton, amino acids, and liquid coral foods.
- Feeding Frequency: 1-2 times per week enhances growth and polyp extension.
- Best Feeding Method: Broadcast feeding ensures even nutrient distribution.
Tank Mates and Compatibility
- Safe Companions: Clownfish, gobies, blennies, shrimp, and snails.
- Caution With: Other corals—Sinularia can release toxins (allelopathy) that inhibit the growth of nearby corals.
- Avoid: Aggressive fish like certain angelfish and butterflyfish, which may nip at soft corals.
Growth Rate and Propagation
- Fast growth rate, quickly forming large tree-like colonies.
- Fragging Method: Use sharp scissors or a scalpel to cut branches and attach them to new rocks or frag plugs.
Common Diseases and How to Prevent Them
- Shedding & Waxing – Sinularia periodically sheds its outer layer to remove debris and algae buildup.
- Bacterial Infections – Can occur in poor water conditions; ensure proper flow and stability.
- Algae Overgrowth – Can smother the coral if excess nutrients are present.
Handling and Acclimation
- Drip acclimation is recommended to gradually introduce the coral to new water conditions.
- Minimize handling, as Sinularia releases mucus when stressed.
Maintenance and Cleaning
- Perform weekly water changes (10-15%) to dilute chemical compounds.
- Use activated carbon or protein skimmers to remove toxins from the water.
Signs of Stress and How to Address Them
- Shrunken or drooping branches – May indicate poor water quality, excessive flow, or lighting issues.
- Faded or bleached coloration – Reduce light intensity and increase feeding.
- Failure to shed mucus layer – Ensure adequate water flow to help with the process.
Troubleshooting Common Issues
- Bleaching – Caused by excessive light exposure; relocate to a lower-light area.
- Toxic Chemical Warfare – Use carbon filtration to absorb Sinularia’s chemical secretions.
- Slow Growth – Increase target feeding and ensure stable alkalinity and calcium levels.
How fast does Sinularia grow?
It has a fast growth rate, quickly branching out in stable conditions.
Can Sinularia be kept in a nano tank?
Yes, but regular pruning and carbon filtration are essential to manage its chemical output.
Does Sinularia require direct feeding?
While it relies on photosynthesis, occasional feeding enhances growth and color vibrancy.
How can I tell if my coral is unhealthy?
Signs include tissue recession, faded colors, or failure to shed.
Can Sinularia be placed near other corals?
It should be spaced away from other corals due to its allelopathic nature.
How do I propagate Sinularia?
Use sharp scissors or a scalpel to cut branches and attach them to frag plugs with rubber bands or glue.
