Blastomussa corals consist of two different species- the smaller polyped blastomussa wellsi, and the larger, fleshier polyped blastomussa merletti.Both are terrific LPS corals for beginners and make an excellent addition to any aquarium.

It is not uncommon to hear the blastomussa merletti referred to as Pineapple Coral, Branched Cup Coral, or Blasto. In its natural environment, the  merletti can be spotted up and down the wide reefs of the Indo Pacific, but very rare in the Caribbean.

The polyps of the blastomussa merletti are extremely large and wide (up to 5cm in diameter), and emerge from the body of the coral through individual tubular stems. These stems are not often seen, since the polyps sheer size covers them when opened to their full ability. The majority of merletti are usually red, or brown in coloring but I have imported, yellow, orange, purple and green.

LPS corals (Large Polyped Stony Corals, of which the blastomussa merletti is a form) are usually captured in the wild as they are generally unsuccessful to propagate in captivity. However, blastomussa merletti are an exception to this rule of thumb, and of the two species of blastomussa (wellsi and merletti), the blastomussa merletti is much easier to maintain in a home tank, since they will grow very quickly and easily given the right conditions. Home enthusiasts love watching blastomussa merlot’s under the actnic lighting of an aquarium, as its neon centers light up in glowing shades of green. Take caution when adjusting the lighting of a reef tank, as blastomussa merlot’s do not thrive under intense lighting conditions. Instead, the light should be adjusted to a dim or moderate level if at all possible. Blastomussa merletti will do best if placed at the bottom of a tank, with average water motion. If the lighting in the home tank is not ideal, the merletti will need to be moved to the middle of the tank where it can access the weaker lighting.

Many corals develop a symbiotic relationship with hard working algae- offering them a place to live in exchange for the energy they produce during photosynthesis. The blastomussa merletti is one of coral, keeping zooxanthellae underneath their surface that will allow them to survive without any supplemental food sources if necessary. The tentacles and polyps on a blastomussa merletti do work to snag and consume organic matters, or drag larger organisms through its sticky, mucus-lined flesh. If maintained in a reef aquarium, hobbyists have had success offering the blastomussa merletti small meaty portions of baby brine shrimp, fish, and squid. The portion sizes should be in line with the polyps ability to fully ingest it.

Propagation

If the blastomussa merletti is attempted to propagate in a home environment, it must be done on healthy, midsized colonies. The skeleton of the blastomussa merletti can be chipped off from the base into segments containing one or more polyps on each piece. Reproduction will continue asexually, as is practiced in the wild.

Unveiling the Splendor of Blastomussa Merletti: A Marine Marvel

Blastomussa Merletti, a captivating species in the realm of marine aquaculture, stands out for its unique attributes and mesmerizing beauty. Commonly known as Blasto Coral, it belongs to the family Mussidae and thrives in the warm, shallow waters of the Indo-Pacific region. This coral is prized by aquarists and marine biologists alike for its vibrant colors and distinctive, puffy polyps. As we delve into the world of Blastomussa Merletti, we’ll explore its habitat, care requirements, propagation techniques, and the scientific intrigue it holds. This journey not only appeals to marine enthusiasts but also educates the general public about the significance of marine biodiversity.

Habitat and Environmental Needs

Ideal Aquatic Conditions for Blastomussa

Blastomussa Merletti thrives in specific aquatic conditions that mimic its natural habitat. This coral prefers water temperatures ranging from 75 to 80 degrees Fahrenheit (24-27 degrees Celsius) and requires a pH level between 8.1 and 8.4. The calcium concentration, vital for skeletal growth, should be maintained at 350-450 ppm. In aquarium settings, moderate lighting and water flow are crucial for its health and coloration. Understanding these parameters is essential for anyone looking to cultivate Blastomussa Merletti in a home aquarium.

Significance of Water Quality in Blasto Coral Growth

The growth and health of Blastomussa Merletti are profoundly influenced by water quality. This coral species is sensitive to nitrates and phosphates; thus, maintaining low levels is paramount. Regular water changes and efficient filtration systems are necessary to keep these parameters in check. Additionally, stable salinity, around 1.025 specific gravity, is crucial for the optimal growth of Blasto Coral. These details emphasize the importance of meticulous water management in sustaining healthy coral ecosystems.

Care and Maintenance

Feeding and Nutritional Requirements of Blasto Coral

Blastomussa Merletti, like many LPS (Large Polyp Stony) corals, has a mixotrophic diet. It derives energy from zooxanthellae, symbiotic algae, and benefits from supplemental feedings. Targeted feeding with microplankton or finely minced seafood enhances its growth and color vibrancy. The frequency and amount of feeding depend on the coral’s size and the nutrient levels in the aquarium. This aspect of care underlines the balance between providing adequate nutrition and avoiding overfeeding, which could compromise water quality.

Managing Disease and Pests in Blastomussa Habitats

Maintaining the health of Blastomussa Merletti involves vigilance against diseases and pests. Common issues include coral bleaching, often a result of environmental stress, and pest infestations like flatworms. Preventive measures such as quarantine for new additions and regular inspections are critical. Effective management strategies include maintaining stable water conditions and employing biological controls, highlighting the need for proactive and informed care in marine aquaculture.

Propagation and Cultivation

Techniques for Fragmenting Blastomussa Coral

Blastomussa Merletti can be propagated through fragmentation, a process that involves carefully dividing the coral into smaller pieces. This technique allows for the sustainable growth of new colonies without harming natural populations. Fragmentation requires precision and an understanding of the coral’s structure. It’s an exciting aspect of coral cultivation, showcasing the potential for both conservation and aquaculture expansion.

Challenges and Successes in Cultivating Blasto Coral

Cultivating Blastomussa Merletti presents both challenges and successes. Factors such as water chemistry, lighting, and flow must be meticulously controlled. Success in cultivation is marked by steady growth, vibrant coloration, and polyp expansion. These successes contribute valuable insights into coral biology and aquaculture techniques, emphasizing the potential for sustainable marine ecosystem management.

Scientific and Ecological Importance

Role of Blastomussa in Coral Reef Ecosystems

Blastomussa Merletti plays a significant role in coral reef ecosystems. As part of the benthic community, it contributes to the structural complexity and biodiversity of reefs. Its presence offers habitat and food sources for various marine organisms, highlighting its ecological importance. Understanding this role is vital for conservation efforts and the study of reef dynamics.

Research and Conservation Efforts Surrounding Blasto Coral

Research on Blastomussa Merletti encompasses studies on its reproduction, growth patterns, and response to environmental changes. These studies are crucial for conservation efforts, as they provide insights into the resilience and vulnerabilities of coral reefs. Conservation initiatives focus on habitat preservation, sustainable aquaculture practices, and public education, all of which are integral to the protection of this remarkable species.
