Green Blastomussa

Last Updated on 02/13/2024

The green blasto is no different then the red, just less common. Both are rare hard coral found in the Indonesian and Pacific Oceans. They are far more common in low laying reefs in Bali, Tonga and Jakarta. Green blastomussa are sometimes mislabeled as a Green Pipe Coral- the two are used interchangeably in some journals and classifications.

The green portion of the  title comes from its neon green center that lightens to a rust or brown on the perimeter, although some types  have red or brown colorings mixed into its body. Green blasto can be found in both  wellsi and  merletti  of hard corals. I have on two occasions imported solid neon green with yellow mouth parts.

Dense and compact when opened, the green coral looks like one large mass, and their rounded appearance looks incredibly similar to a brain coral. Although one would not be able to tell at first glance, there is calcium based skeletal underneath it’s blooms, from which the green polyps actually emerge via stony tubes. These are not often seen, since the polyps take center stage when the coral colony is expanded. All blastomussa corals, including green have nocturnal polyps.

Because of its colorful coat and difficulty to harvest, the green blastomussa are a favorite among reef enthusiasts and hobbyists. If choosing between a wellsi and  merletti, the beginner aquarists will have higher rates of success with the green merletti. Within an artificial tank, the coral will spread quickly and expand over many surfaces in groups of smaller colonies. Like any coral, the green blastomussa will require optimal tank conditions to thrive. Tailored lighting, sufficient water movement, food quantities and the addition of trace minerals are a must. The coral should be purchased already attached to a piece of live rock, but if not, use a coral-safe glue to secure the specimen to similar substrate. Depending on the lighting conditions, the coral may even be placed in the bottom of the aquarium on fine sand.

If the  polyps are not expanding fully, the culprit could be that the coral is placed too close to the light source or is in too high of water flow. For this reason, place the blasto out of direct light in moderate (not direct) current. They prefer a diet rich in marine snow, phytoplankton and other organisms for its filter feeding methods.

The coral is very peaceful in nature, and does not have a history of encroaching on neighboring coral or other creatures that reside within close distances. However, it should be kept away from stinging corals that could potentially damage the green blastomussa with their far reaching tentacles.

Exploring the Vibrant World of Green Blastomussa: A Dive into Marine Splendor

Introduction

Dive into the enchanting underwater realm where the Green Blastomussa, a coral of stunning beauty, reigns supreme. Known scientifically as Blastomussa wellsi, this species is a marvel in the marine aquascaping world. Favoured for its vivid green hues and unique polyp structure, the Green Blastomussa has captivated both novice and seasoned aquarists. In this exploration, we delve into the fascinating aspects of this coral, from its habitat and growth patterns to its role in marine ecosystems and aquaculture. Join us as we uncover the secrets of the Green Blastomussa, a true gem of the ocean.

Habitat and Environmental Preferences

Identifying Ideal Conditions for Growth

Green Blastomussa thrives in specific conditions, reminiscent of its natural habitat in the Indo-Pacific oceanic regions. These corals prefer moderate lighting and water flow, mimicking the gentle currents of their native reef environments. Scientifically, they require a stable pH range of 8.1-8.4 and temperatures between 75-80°F (23.8-26.7°C). Understanding these parameters is crucial for replicating their natural habitat in captivity, ensuring their health and vibrancy.

Adaptation to Varied Environments

Remarkably adaptable, Green Blastomussa has shown resilience in various marine settings. This adaptability is attributed to its zooxanthellae, symbiotic algae that live within its tissues. These algae perform photosynthesis, providing essential nutrients to the coral. This symbiotic relationship is a perfect example of mutualism, where both organisms benefit, and is pivotal in the coral’s ability to thrive in diverse environments.

Propagation and Aquaculture

Techniques in Coral Fragmentation

Coral aquaculturists highly regard Green Blastomussa for its ease of propagation, primarily through fragmentation. This process involves carefully dividing the coral’s polyps, enabling each fragment to grow independently. This method not only facilitates the sustainable cultivation of these corals but also aids in the conservation of natural reef ecosystems by reducing wild harvest.

Challenges in Sustainable Cultivation

While propagation is relatively straightforward, maintaining the delicate balance required for the coral’s growth poses challenges. Issues such as water chemistry, nutrient levels, and light intensity must be meticulously managed. Overcoming these challenges is key to successful cultivation, ensuring the sustainability and longevity of Green Blastomussa populations in captivity.

Interaction with Marine Life

Role in the Reef Ecosystem

Green Blastomussa plays a pivotal role in reef ecosystems. As a reef-building coral, it provides essential habitat and shelter for various marine species. Its structure offers protection and breeding grounds for small fish and invertebrates, contributing significantly to biodiversity.

Symbiotic Relationships

Beyond its physical structure, Green Blastomussa engages in fascinating symbiotic relationships. The most notable is with its zooxanthellae, which, through photosynthesis, produce oxygen and help remove waste products. Additionally, it serves as a food source for certain fish and invertebrate species, highlighting its integral role in the marine food web.

Care and Maintenance in Aquariums

Ensuring Optimal Conditions

For aquarists aspiring to nurture Green Blastomussa, understanding and replicating its natural habitat is essential. Regular monitoring of water parameters, such as salinity, alkalinity, and nutrient levels, is crucial. Additionally, providing moderate lighting and water flow mimics the coral’s natural environment, promoting healthy growth.

Common Issues and Solutions

Common issues faced in cultivating Green Blastomussa include algae overgrowth, polyp retraction, and bleaching. Addressing these challenges involves adjusting lighting, maintaining water quality, and careful feeding practices. With proper care, these corals can become a thriving centerpiece in any marine aquarium.

Conclusion

The Green Blastomussa is more than just an ornamental coral; it’s a testament to the beauty and complexity of marine life. Understanding and preserving this species is vital, not only for the aesthetic appeal it brings to aquariums but for its ecological importance. Whether you’re a marine enthusiast or a casual observer, the allure of the Green Blastomussa is undeniable, a living piece of art that connects us to the vast mysteries of the ocean.
