Blastomussa Vivida

Blastomussa Vivida — known in Japanese as Otabasango — is a stony coral in the genus Blastomussa, first described as a new species in 2014. It grows as a colony whose corallites extend from a shared base and gradually separate from one another as the colony matures, giving each specimen a distinctive, evolving look. Its vivid red and green coloration is a major draw, and how those colors read can shift depending on lighting. Most recorded specimens come from Japan, making it a familiar sight among Japanese reef keepers. It suits intermediate-level aquarists, rewarding their experience with a striking presence in the tank.

About Blastomussa Vivida

Blastomussa Vivida is a stony coral prized for its vivid red and green coloration, forming a colony whose corallites gradually separate as it matures — an intermediate-level species growing to a colony diameter of over ten centimeters.

7 things to know before welcoming a Blastomussa Vivida

  1. 1A Distinctive Growth Pattern

    Blastomussa Vivida grows with corallites extending from a shared base, gradually separating from one another as the colony matures. Even within a single colony, different areas can take on distinct looks over time.

  2. 2Suited to Intermediate Keepers

    This species is considered suitable for intermediate-level keepers who are already comfortable with basic reef tank water quality management. If you're new to coral keeping, it's a good idea to build experience with hardier species first.

  3. 3Vivid Red and Green Coloration

    Its biggest draw is vivid red and green coloration, which varies from specimen to specimen. How the colors appear can shift depending on the type and angle of lighting, so it's worth observing and adjusting after placement.

  4. 4Colonies Reach Over 10 cm

    Mature colonies can grow to a diameter of over ten centimeters. Leaving extra space around the coral as it grows can reduce the need for layout changes later on.

  5. 5Give It Space From Neighbors

    Corals of various species can interfere with one another when placed too close together. When positioning Blastomussa Vivida, it's wise to leave enough distance from surrounding livestock.

  6. 6Feeding Can Support Color and Growth

    Beyond photosynthesis, target feeding is thought to help support growth and coloration. Whether and how often to feed depends on your specific setup, so it helps to observe and adjust as you go.

  7. 7Stabilize Conditions Before Adding It

    It's important to have stable water quality and lighting in place before bringing this coral home. It tends to be especially sensitive right after introduction, so watch its condition and water parameters closely during that period.
