The Best Corals for NZ Reef Aquariums
Discover the best corals for NZ reef aquariums, including vibrant options like Zoanthids and Acan Lords. Learn how to care for them effectively.
Introduction to Corals
Corals are the vibrant and dynamic foundation of any reef aquarium. They not only enhance the aesthetic appeal of your aquatic environment but also play a crucial role in maintaining the ecosystem's balance. In New Zealand, reef aquariums have gained immense popularity due to the country's rich marine biodiversity and the appeal of bringing a slice of that underwater paradise into homes and offices. Understanding the variety of corals available and their specific care requirements is key to creating a thriving reef aquarium.
Corals are marine invertebrates that belong to the phylum Cnidaria. They are primarily known for their calcium carbonate structures, which contribute to the formation of coral reefs. Corals come in various shapes, sizes, and colours, each offering unique characteristics and care needs. For NZ aquarists, selecting the right corals is vital for ensuring their reef aquariums flourish with minimal issues.
Top Coral Picks for NZ Aquariums
When selecting corals for your NZ reef aquarium, consider both aesthetics and compatibility with your tank environment. Here are some top coral choices that thrive well in local aquariums:
Zoanthids
Zoanthids are a popular choice due to their vibrant colours and relative ease of care. They are hardy and can adapt to various lighting conditions, making them ideal for beginners. Their polyps come in a range of hues, from bright oranges to deep purples, adding a splash of colour to any tank.
Acan Lords
Acan Lords, scientifically known as Acanthastrea, are another favourite among NZ reef enthusiasts. Known for their striking patterns and rich colours, they require moderate lighting and a stable environment. Regular feeding with meaty foods can enhance their growth and vibrancy.
Pulsing Xenia
Pulsing Xenia is admired for its unique pulsating motion, which adds dynamic movement to reef aquariums. This coral requires moderate lighting and benefits from stable water parameters. Although it can grow rapidly, regular pruning can help manage its spread.
Sarcopython (Leather Coral)
Leather corals, such as Sarcopython, are robust and adaptable. They thrive in moderate lighting and can tolerate a range of water conditions, making them an excellent choice for beginners. Their unique texture and growth patterns add depth to any reef setup.
Montipora
Montipora species are known for their diverse forms and colours. They can be encrusting, plating, or branching, offering flexibility in aquascaping. These corals require moderate to high lighting and benefit from stable calcium and alkalinity levels.
Coral Care Tips
Maintaining corals in a reef aquarium involves understanding their specific requirements and providing suitable conditions for their growth. Here are some expert tips for coral care in NZ:
Lighting
Corals rely on light for photosynthesis, making it a critical factor in their care. Ensure your lighting system provides the appropriate intensity and spectrum for the corals in your tank. LED lighting systems are popular for their energy efficiency and customisability.
Water Parameters
Stable water parameters are essential for coral health. Regularly test and maintain ideal levels of salinity, pH, calcium, alkalinity, and magnesium. Implement a reliable filtration system and perform regular water changes to keep these parameters in check.
Feeding
While many corals obtain nutrients through photosynthesis, supplemental feeding can promote growth and colouration. Use high-quality coral foods and target feed species that benefit from additional nutrition, such as Acan Lords and certain LPS corals.
Flow
Proper water flow is important for nutrient distribution and waste removal. Corals like Pulsing Xenia benefit from moderate flow, while others, such as Montipora, may require higher flow rates. Adjust powerheads and circulation pumps to achieve optimal conditions.
Placement
Consider the specific lighting and flow needs of each coral when placing them in your tank. Avoid overcrowding and ensure that aggressive species, which may extend sweeper tentacles, are placed at a safe distance from others.
