Coral Care Info Blastomussa

Blastomussa, commonly referred to as Blasto Coral, is a stunning Large Polyp Stony (LPS) coral known for its bright, fleshy polyps and easy-care nature. Available in striking colors such as red, green, purple, and blue, Blastomussa is a great choice for beginner and experienced reef keepers alike. Unlike some aggressive LPS corals, Blastos are peaceful and adaptable, making them a perfect addition to mixed reef tanks.
Natural Habitat and Location in the Wild
Blastomussa is native to the Indo-Pacific region, particularly in Australia, Indonesia, the Philippines, and the Great Barrier Reef. It is commonly found in sheltered reef slopes and lagoons, where it grows in low-light conditions with moderate water movement. This coral thrives in nutrient-rich environments, making it more forgiving in home aquariums than some other LPS species.
Why Choose Blastomussa for Your Reef Tank?
- Peaceful and Reef-Safe – Compatible with most corals and reef inhabitants.
- Low Light Requirement – Thrives in shaded areas, making it adaptable to different setups.
- Hardy and Beginner-Friendly – Can tolerate minor fluctuations in water parameters.
- Moderate Growth Rate – Expands steadily without overwhelming the tank.
Optimal Water Parameters
Maintaining stable conditions ensures the best health and coloration for Blastomussa:
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 | 5-10 ppm |
Phosphate | 0.03-0.07 ppm |
Weekly water changes (10-15%) help maintain stability and nutrient balance.
Tank Size and Setup
- Minimum Tank Size: 20 gallons or larger.
- Placement: Prefers low to mid-levels of the tank, ideally in shaded or indirect lighting areas.
- Substrate Considerations: Can be placed on rockwork or the sand bed, but ensure stable positioning.
Lighting Requirements
Blastomussa prefers low to moderate lighting, making it ideal for shaded areas in reef tanks.
- PAR Range: 50-150 PAR
- Lighting Type: LED, T5, or hybrid setups with adjustable intensity.
- Lighting Schedule: 8-10 hours per day, with a gradual ramp-up and ramp-down to reduce stress.
Water Flow and Circulation
- Moderate, indirect flow keeps detritus from settling while allowing proper polyp expansion.
- Avoid strong, direct currents, which can cause polyps to retract.
- Randomized flow patterns help mimic natural reef conditions.
Feeding and Nutrition
Blastomussa benefits from both photosynthesis and supplemental feeding.
- Preferred Foods: Mysis shrimp, brine shrimp, reef roids, and marine pellets.
- Feeding Frequency: 2-3 times per week enhances growth and coloration.
- Best Feeding Method: Target feeding ensures nutrients are absorbed efficiently.
Tank Mates and Compatibility
- Safe Companions: Clownfish, gobies, blennies, shrimp, and snails.
- Caution With: Other LPS corals—Blastos are non-aggressive, but they need space to expand.
- Avoid: Aggressive fish such as certain angelfish and butterflyfish that may nip at the polyps.
Growth Rate and Propagation
- Moderate growth rate, with polyps budding off to form colonies.
- Fragging Method: Use a bone cutter or coral saw to separate healthy polyps.
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 water 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.
- Avoid excessive handling, as its fleshy polyps are delicate.
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 closed polyps – May indicate poor water quality, excessive flow, or inadequate lighting.
- Faded or bleached coloration – Reduce light intensity and increase feeding.
- Receding tissue – Ensure stable water conditions and provide supplemental feeding.
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.
How fast does Blastomussa grow?
It has a moderate growth rate, forming new polyps gradually over time.
Can Blastomussa be kept in a nano tank?
Yes, but stable water parameters and adequate space for polyp expansion are essential.
Does Blastomussa require direct feeding?
While it survives on photosynthesis, target feeding enhances growth and color vibrancy
How can I tell if my coral is unhealthy?
Signs include retracted polyps, faded colors, or slow tissue recession.
Can Blastomussa be placed near other corals?
It is peaceful, but it should be spaced from more aggressive corals.
What is the best way to frag Blastomussa?
Use a bone cutter or coral saw to carefully separate polyps.
