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.

Blastomussa Vivida key facts
- Care level
- Intermediate
- Size
- Colonies to around 10-20 cm across
- Temperature
- 24〜26℃
- Diet
- Mainly nutrition from symbiotic zooxanthellae, supplemented with meaty coral foods offered at night.
- Lighting
- LiveAquaria gives moderate lighting for Blastomussa. Strong light makes the tissue contract and the colour fade, so place it low down where the light is gentle.
- Flow & Placement
- LiveAquaria calls for low flow and bottom placement. A direct stream damages the inflated tissue, so keep the flow indirect and gentle.
- Water Temperature & Quality
- Water 24-26C, specific gravity 1.023-1.025, salinity 33-35 ppt, KH 8-12. It consumes calcium and magnesium, so test and replenish them regularly.
- Feeding
- Most of its nutrition comes from its zooxanthellae. It extends its tentacles at night, so small amounts of meaty coral food after lights-out encourage new corallites.
- Notes
- The species was only described in 2014 and is often traded without being separated from B. merleti or B. wellsi. As a scleractinian it is on CITES Appendix II and international trade requires permits.

7 things to know before welcoming a Blastomussa Vivida
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.
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.
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.
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.
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.
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.
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.
