Red Bright Modern Coral

Cynarina lacrymalis, commonly referred to as the Red Bright Modern Coral, is a fascinating species of stony coral belonging to the family Lobophylliidae. This coral is predominantly found in the warm waters of the western Indo-Pacific Ocean. Its distinct flat, cup-like appearance, often resembling a doughnut or cat's eye, makes it a popular choice among aquarium enthusiasts. The vibrant red coloration can provide an eye-catching contrast to the more muted tones of many other corals, contributing to the overall aesthetic appeal of reef tanks.

This solitary coral typically displays a broad, fleshy disc that can expand and contract based on environmental conditions. Cynarina lacrymalis is known for its ability to thrive in low-light conditions, making it a versatile addition to various aquarium setups. In nature, it primarily inhabits shallow reefs, often found nestled in crevices or on sandy substrates, where it can capture plankton and organic debris with its tentacles during the night.

Behaviorally, the Red Bright Modern Coral is relatively peaceful, although it can exhibit aggressive tendencies towards nearby corals if they encroach too closely. This species relies on a symbiotic relationship with zooxanthellae, allowing it to photosynthesize and gain energy from sunlight, further enhancing its vibrant colors. Its unique structure not only serves as a habitat for various marine organisms but also plays a role in reef building and ecosystem stability.

As an aquarium specimen, Cynarina lacrymalis can serve as a focal point due to its striking appearance and adaptability. However, it requires careful consideration regarding its placement and compatibility with other tank inhabitants to ensure a harmonious environment.

Caring for Cynarina lacrymalis requires attention to specific water parameters to ensure optimal health. The ideal temperature range for this coral is between 24°C and 28°C, with a salinity level of 1.023 to 1.025 ppt. Maintaining a stable pH between 8.1 and 8.4 is crucial for its well-being. Additionally, this coral benefits from moderate water flow and should be placed in areas with indirect lighting to prevent bleaching.

Feeding for Cynarina lacrymalis is primarily through photosynthesis, thanks to its symbiotic zooxanthellae, but it also appreciates supplemental feeding. Offering finely crushed meaty foods or plankton once or twice a week can enhance its growth and vibrancy. When introducing this coral into a new environment, acclimation should be done slowly over several hours to reduce stress, ideally through a drip method.

Quarantine is recommended before introducing the coral into a display tank to prevent potential disease transmission. It is generally compatible with other corals and fish but should be monitored for aggressive behavior toward closely placed corals. Providing ample space around this species can help mitigate territorial disputes and promote a peaceful community tank.

Cynarina lacrymalis ships well under stable conditions, requiring careful packing to minimize stress. A packing density of 1-2 pieces per shipping container is advised to prevent damage. This coral is moderately temperature-sensitive, necessitating a shipping temperature between 24°C to 28°C. The species is not listed under CITES, simplifying export regulations.
