Extreme Blasto merletti colony 20+ heads

Blastomussa corals, commonly referred to as Blastos, are a popular type of Large Polyp Stony (LPS) coral prized for their fleshy polyps and vibrant colors. These corals are available in two primary species, Blastomussa wellsi and Blastomussa merletti, which differ in polyp size and growth structure. Blastos come in a stunning range of hues, including reds, greens, oranges, and purples, often with contrasting centers that make them a striking addition to any reef tank.

Blastomussa thrive in stable water conditions with slightly elevated nutrient levels, making them relatively forgiving compared to other LPS corals. Maintaining consistent parameters is essential for their health and vibrant coloration.

Calcium: 400–450 ppm

Alkalinity: 8–12 dKH

Magnesium: 1250–1350 ppm

Nitrates: 5–15 ppm

Phosphates: <0.10 ppm

Temperature: 76–80°F

Salinity: 1.024–1.026

Blastos tolerate moderate nutrient levels but are sensitive to extreme fluctuations. Regular water changes and careful parameter monitoring will help them thrive and maintain their bold colors.

Lighting

Blastomussa corals thrive under low to moderate lighting conditions, with a PAR range of 50–150 being ideal. These corals are well-suited for shaded or lower-light areas of the tank, where they can expand fully and maintain their vibrant colors. Excessive light intensity can cause bleaching or tissue stress, so avoiding high-light zones is critical.

we use advanced lighting systems such as kessil and T5 setups to replicate the soft lighting conditions Blastos experience in their natural habitats. Blue-spectrum lighting enhances their bold and contrasting colors, making them a standout feature in reef aquariums.
