Acropora Coral: Species and Care Guide
Acropora corals are among the most sought-after species in the reef-keeping hobby. Known for their stunning colors, intricate branching structures, and fast growth, they form the backbone of many natural coral reefs. However, their beauty comes with the challenge of maintaining stable conditions to keep them thriving.
Different Species of Acropora
There are over 150 species of Acropora, each with unique growth patterns and coloration. Some of the most popular in the reef hobby include:
• Acropora tenuis – Known for vibrant blues, greens, and purples, with thick, stubby branches.
• Acropora millepora – A favorite for its fuzzy polyps and bright pink, red, or orange hues.
• Acropora valida – Displays deep purples and blues with compact, clustered growth.
• Acropora tortuosa – Recognized for its twisting branches and striking blue or purple coloration.
• Acropora echinata – Features sharp, tapered branches with electric blue and teal tones.
Acropora Coral Care Guide
Acropora are classified as Small Polyp Stony (SPS) corals, requiring high-intensity lighting, strong water flow, and stable water parameters.
Lighting: High PAR (250-400) with full-spectrum LED, T5, or metal halides.
Water Flow: Strong, randomized flow to prevent detritus buildup and ensure proper gas exchange.
Water Parameters:
Temperature: 76-78°F
Salinity: 1.025 SG
pH: 8.1-8.4
Alkalinity: 8-9 dKH
Calcium: 400-450 ppm
Magnesium: 1250-1350 ppm
Nutrient Levels: Low but not zero; aim for nitrate (5-10 ppm) and phosphate (0.02-0.05 ppm).
Feeding: Though Acropora primarily rely on photosynthesis, they benefit from amino acids, phytoplankton, and coral food supplements.
Challenges & Tips
Acropora are highly sensitive to parameter swings. Regular testing, stable dosing of alkalinity and calcium, and consistent maintenance are key to success. Introducing them to a mature reef system with optimized conditions will increase survival rates.
Acropora corals are the pinnacle of SPS reef-keeping, rewarding dedicated hobbyists with incredible colors and growth. With the right care, they can transform any reef tank into a vibrant underwater masterpiece.
