Description
Blastomussa merletti is a large polyp stony (LPS) coral known as a pineapple coral, characterized by its round, flower-like polyps and vibrant colors such as red, green, purple, and orange. It is a relatively easy to keep coral, suitable for beginners, that grows in clusters and is found in the Indo-Pacific region. This species thrives in low to moderate light with gentle water flow and can be supplemented with food.
Physical characteristics
Develop into small, round, flower-like structures that can resemble mushroom corals.
Often displays a mix of bright colors, commonly red with green oral discs or a combination of red, purple, and green. Other colors can include pink, orange, brown, or dark grey with white margins.
The mantle and tentacles are often visible and extended during the day.
The surface can be continuous, sometimes obscuring the underlying growth form.

Habitat and care
Native to the west and central Indo-Pacific region. It is also popular in reef aquariums.
Prefers low to moderate lighting, and can be overexposed in very bright conditions. High-end LED or T5 lighting is recommended.
Needs a low to moderate flow. Excessive flow can be detrimental, so gentle, indirect water movement is best.
Should be mounted on stable rock or sand, with some space around it, and kept away from aggressive neighbors.
Requires stable water parameters, including Calcium 400-450 ppm
Alkalinity 8-12dKH),
Magnesium 1250 -1350ppm),
and low levels of Nitrates 5-15 ppm
and Phosphates< 0.10ppm
Optimal temperature is between $76–80^\circ$F.

Feeding and growth
-
Supplementation: Can be supplemented with LPS pellets or other small particle foods to promote growth and color, though it is not strictly necessary as it is photosynthetic.
-
Growth: Grows in tight clusters and can spread over rockwork to create colorful spots in a reef tank.
-
Temperament: Considered a peaceful coral.
