LPS Corals: Care, Feeding, and Best Practices for a Thriving Reef Tank

Introduction to LPS Corals

Large Polyp Stony (LPS) corals, distinguished by their significantly large polyps, hold a unique position in the reef-keeping hobby. Unlike their small polyp stony (SPS) counterparts, LPS corals feature sizable, fleshy polyps that are not only visually striking but also indicative of their specialized care requirements. Among the LPS corals, species such as Acanthastrea, Hammer, and Torch corals are particularly favored for their vibrant colors and fascinating structures.

Native to various marine environments, LPS corals are typically found in the Indo-Pacific region where they inhabit both shallow and deep reef zones. This wide range allows them to adapt to varying light and flow conditions, making them quite versatile for inclusion in reef tanks. Their distinctive appearances, often characterized by undulating tentacles and brilliant hues, contribute significantly to the aesthetic enhancement of marine aquariums.

One of the most celebrated LPS corals is the Acanthastrea, known for its chunky morphology and dazzling array of colors, ranging from deep reds to electric blues. Hammer corals, with their hammer or anchor-shaped tentacles, add dynamic movement to the tank environment, while Torch corals are renowned for their long, flowing tentacles that provide a mesmerizing visual effect.

The appeal of LPS corals extends beyond their looks; their relatively easier maintenance compared to SPS corals makes them a favorite among reef enthusiasts, both novice and experienced. Their ability to thrive under moderate lighting and water flow conditions, coupled with their hardiness, renders them ideal for hobbyists aiming to cultivate a lively and picturesque reef tank. By offering a combination of beauty and manageable care, LPS corals have firmly established themselves as an integral part of the modern reef aquarium.

Essential Care and Feeding of LPS Corals

When it comes to maintaining a thriving reef tank, understanding the essential care requirements of Large Polyp Stony (LPS) corals is crucial. Proper tank conditions play a vital role in the health and longevity of these corals. Ensuring optimal water parameters is the first step. The pH level should be maintained between 8.1 and 8.4, with ideal temperatures ranging from 75°F to 80°F. Salinity should be kept consistent at 1.025 specific gravity. Stability in these parameters is necessary to avoid stressing the LPS corals and discouraging unwanted algae growth.

Lighting is another critical factor. LPS corals generally require moderate lighting. T5 fluorescent bulbs or LED lights that provide spectrums mimicking natural sunlight are ideal. Too much light can cause bleaching, while insufficient light can stunt their growth. It’s advisable to acclimate your corals to new lighting gradually to prevent shock.

In terms of water flow, LPS corals prefer moderate, indirect currents. Direct, strong flow can damage their delicate polyps, while stagnant water can lead to detritus buildup and increased susceptibility to diseases. An adjustable powerhead can help create the right water movement.

Feeding practices for LPS corals are also distinct. While these corals obtain some nutrients through photosynthesis via their symbiotic zooxanthellae, supplemental feeding is beneficial. Suitable foods include frozen varieties like mysis and brine shrimp, phytoplankton, and specially formulated coral foods. Additionally, occasional feeding of meaty foods helps in delivering necessary proteins and fats.

For effective feeding, target feeding using a pipette or turkey baster can ensure that food reaches the coral polyps directly. This practice reduces waste and prevents nutrient spikes in the tank. Feeding once or twice a week is generally enough, although denser, more elaborate setups might require varied schedules. Monitoring coral response to feeding can also help in fine-tuning the frequency and amount.

By adhering to these essential care and feeding guidelines, enthusiasts can foster vigorous and colorful LPS corals, contributing to the overall beauty of their reef tanks.

Tips and Tricks for Maintaining Thriving LPS Corals

Maintaining thriving Large Polyp Stony (LPS) corals in a home aquarium requires a combination of strategic placement, diligent tank maintenance, and effective pest management. Understanding the placement needs of various species is crucial. For instance, some LPS corals like the Euphyllia species prefer moderate lighting and gentle water flow, while others like Acanthastrea thrive in low light and indirect flow. By positioning corals in their ideal locations within the tank, hobbyists can avoid aggression incidents and optimize growth conditions.

Regular tank maintenance is another pivotal aspect of ensuring coral health. Consistent water changes, typically 10-20% biweekly, help in maintaining stable water parameters essential for LPS coral survival. Monitoring key parameters such as calcium, alkalinity, magnesium, and nitrate levels is equally important. Stability in these parameters supports skeletal growth and overall coral vitality. The use of high-quality test kits and supplements can aid in keeping these parameters within the optimal range.

The threat of coral pests and diseases is a significant concern for any reef tank. Implementing preventive measures like quarantining new corals or using coral dips can greatly reduce the risk of introducing pests such as flatworms or nudibranchs into the main aquarium. Additionally, promptly addressing any signs of disease, such as tissue recession or discoloration, can prevent further spread and preserve the health of the coral colony.

For hobbyists looking to enhance coral growth and health, the use of coral additives can be beneficial. Products containing trace elements and amino acids have been shown to support the metabolic processes of LPS corals, encouraging more vibrant coloration and robust growth. However, it's important to follow manufacturer instructions to avoid overdosage, which can have adverse effects.

Finally, propagating LPS corals through methods such as fragging can be a rewarding practice. Tools like coral cutters and frag plugs facilitate this process, allowing hobbyists to cultivate new colonies and share healthy specimens with fellow enthusiasts. By adopting these tips and tricks, aquarists can enjoy a vibrant, thriving reef tank teeming with healthy LPS corals.
