Coral Care Info Micromussa

Micromussa, commonly known as Micro Lords or Mini Brain Coral, is a Large Polyp Stony (LPS) coral known for its bright, multi-colored polyps and fleshy, encrusting growth pattern. Available in red, orange, blue, green, yellow, and purple varieties, Micromussa is a hardy and beginner-friendly coral that thrives in low to moderate lighting and gentle water flow.
Closely related to Acanthastrea, Micromussa corals are less aggressive, making them a great option for mixed reef aquariums. They have a moderate growth rate and do well with target feeding, which enhances their vibrant coloration and overall health.
Natural Habitat and Location in the Wild
Micromussa corals are found in the Indo-Pacific region, particularly in Australia, Indonesia, Japan, Fiji, and the Great Barrier Reef. They typically inhabit shallow reef slopes and lagoonal environments, where they grow on rocky substrates and coral rubble, often in lower-light conditions.
Why Choose Micromussa for Your Reef Tank?
- Highly Colorful & Eye-Catching – Offers a variety of stunning color morphs.
- Beginner-Friendly & Hardy – Tolerates minor parameter fluctuations.
- Moderate Growth Rate – Expands steadily under proper care.
- Less Aggressive than Other LPS Corals – Can be placed near peaceful corals.
Optimal Water Parameters
Maintaining stable water conditions ensures the best health and coloration for Micromussa:
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 prevent nutrient imbalances.
Tank Size and Setup
- Minimum Tank Size: 20 gallons or larger.
- Placement: Prefers mid to lower areas of the tank, away from direct currents.
- Substrate Considerations: Best placed on rockwork or frag racks, where it can encrust naturally.
Lighting Requirements
Micromussa thrives under low to moderate lighting, which helps maintain its vivid coloration.
- PAR Range: 50-150 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
- Low to 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
Micromussa corals benefit from both photosynthesis and direct feeding, absorbing nutrients through their fleshy 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 tentacles extend.
Tank Mates and Compatibility
- Safe Companions: Clownfish, gobies, blennies, shrimp, and snails.
- Caution With: Other LPS corals—while not highly aggressive, Micromussa should have some space to prevent territorial disputes.
- Avoid: Aggressive fish like certain angelfish and butterflyfish, which may nip at polyps.
Growth Rate and Propagation
- Moderate growth rate, expanding as an encrusting mat over rockwork.
- 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 retracted tissue – May indicate poor water quality, excessive flow, or lighting issues.
- Faded or bleached coloration – Reduce light intensity and increase feeding.
- Receding tissue – Ensure stable water conditions and avoid aggressive tank mates.
Troubleshooting Common Issues
- Bleaching – Caused by excessive light exposure; relocate 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 Micromussa grow?
It has a moderate growth rate, gradually encrusting rockwork over time.
Can Micromussa be kept in a nano tank?
Yes, but stable water parameters and careful placement are essential.
Does Micromussa require direct feeding?
While it relies on photosynthesis, target feeding enhances growth and color vibrancy.
How can I tell if my coral is unhealthy?
Signs include receding tissue, faded colors, or lack of polyp extension.
Can Micromussa be placed near other corals?
It is semi-aggressive and should be spaced away from more aggressive corals to prevent damage.
What is the best way to frag Micromussa?
Use a bandsaw or bone cutter to create clean frag sections for propagation.
