Green Metalic Modern Coral

Cynarina lacrymalis, commonly referred to as the Green Metallic Modern Coral, is a stunning species of stony coral belonging to the Lobophylliidae family. This coral is recognized for its flat, cup-like shape and bright green, metallic coloration that can captivate aquarists and enhance any reef aquarium. Its various common names, including solitary cup coral and cat's eye coral, reflect its distinctive appearance and solitary nature, as it generally exists as a single polyp rather than forming large colonies.

Naturally inhabiting the warm, shallow waters of the western Indo-Pacific Ocean, Cynarina lacrymalis thrives in environments rich in coral reefs. These corals prefer sandy or rubble substrates where they can anchor themselves securely, allowing them to feed effectively while being protected from strong currents. The species exhibits a remarkable ability to adapt to varying light conditions, making it suitable for diverse aquarium setups.

In terms of behavior, Cynarina lacrymalis is primarily nocturnal, extending its tentacles at night to capture plankton and small fish for nourishment. During the day, it retracts its tentacles and relies on photosynthetic symbiotic algae (zooxanthellae) for energy. This unique feeding strategy allows it to thrive in both nutrient-rich and nutrient-poor environments, providing flexibility for aquarists.

Overall, the Green Metallic Modern Coral not only adds aesthetic value to marine tanks but also serves as a crucial component of the reef ecosystem, contributing to biodiversity and habitat structure. Its mesmerizing colors and unique form make it a sought-after species among aquarium enthusiasts and professionals alike.

To successfully care for Cynarina lacrymalis, it is essential to maintain specific water parameters. Ideal temperature ranges from 24°C to 28°C, with a salinity of 1.023 to 1.025 ppt. The pH should be kept between 8.1 and 8.4 to ensure optimal health. A minimum tank size of 100 liters is recommended to provide adequate space for growth and stability.

Feeding the Green Metallic Modern Coral involves a combination of direct feeding and light exposure. During the day, ensure moderate lighting to support photosynthesis, while at night, target feed with small particles of meaty foods or specialized coral foods to supplement its diet. Compatibility with other tank inhabitants is generally favorable, but caution should be taken with aggressive species that may harm this delicate coral.

Acclimation is critical for Cynarina lacrymalis. Gradually introduce the coral to its new environment over several hours by floating the sealed bag in the aquarium and slowly mixing tank water into the bag. Quarantine new arrivals for at least two weeks to prevent the introduction of pests and diseases. Regular monitoring of water quality and coral health is essential for long-term success.

Cynarina lacrymalis is suitable for shipping, but careful handling is required to prevent damage. Packing density should be low to avoid crushing, and it is important to maintain stable temperatures between 24°C and 28°C during transport. This species is not listed under CITES, allowing for easier export, but compliance with local regulations is necessary.
