Two Colour Big Polyp Blastomussa Cora

Blastomussa wellsi, commonly known as the Two Colour Big Polyp Blastomussa Cora, is a captivating species of large polyp stony coral found primarily in the west and central Indo-Pacific regions. This unique coral is characterized by its large, fleshy polyps that can exhibit a stunning variety of colors, typically featuring vibrant greens, reds, and blues. The polyps can expand significantly during the night, creating a mesmerizing display, making it a favorite among coral enthusiasts.

In terms of natural history, Blastomussa wellsi thrives in shallow waters, often nestled in protected reef environments where it can receive moderate light. This species forms colonies that can grow in size, creating a beautiful and colorful addition to the marine landscape. The coral's skeleton is made of calcium carbonate, which provides structural integrity and contributes to reef building in its natural habitat.

Behaviorally, Blastomussa wellsi is known for its relatively peaceful nature, making it compatible with a variety of marine species. However, it can exhibit aggressive behavior towards similar corals, particularly during feeding and when space is contested. This behavior is typical of many stony corals, which utilize their sweeper tentacles to ward off competitors and protect their territory.

In its habitat, this coral prefers low to moderate water movement and can often be found in areas with plenty of nutrients. Its adaptability to varying light conditions allows it to thrive in diverse environments, making it a resilient choice for aquarium settings as well. With proper care, the Two Colour Big Polyp Blastomussa Cora can flourish, adding both beauty and ecological value to marine displays.

To successfully keep Blastomussa wellsi, it is essential to maintain stable water parameters. Ideal temperature ranges from 24°C to 28°C, with a salinity of 1.023 to 1.025 ppt. pH levels should be kept between 8.1 and 8.4 to promote optimal growth. This coral benefits from moderate light and water flow, allowing for proper expansion and feeding.

Feeding should include a diet of zooplankton and micro-particles, along with occasional offerings of liquid coral foods to supplement their nutritional needs. It's vital to monitor water quality regularly, especially nitrate and phosphate levels, as high nutrient conditions can lead to algal blooms that may harm the coral.

In terms of compatibility, Blastomussa wellsi generally coexists well with many fish and invertebrates but should be placed away from aggressive corals to prevent damage. Acclimation should be gradual; introduce the coral to the aquarium slowly to avoid shock. A quarantine period of at least two weeks is recommended before introducing it into the main display to ensure it is free from pests and diseases.

Blastomussa wellsi is suitable for shipping due to its resilience, but care should be taken to maintain stable temperatures during transit. Optimal packing density should be determined based on the size and condition of the corals, ensuring they are cushioned to prevent damage. The coral is sensitive to drastic temperature changes, so shipping should ideally occur in temperatures between 24°C and 26°C. CITES status for this species is currently not applicable, allowing for straightforward export procedures.
