Acanthastrea echinata
Acanthastrea echinata is a striking LPS coral that forms massive and often irregularly shaped colonies. The coral's surface consists of large corallites, or polyps, surrounded by thick tissue and a distinctly structured appearance. This species is especially known for its vibrant colors and contrasting patterns.
Acanthastrea echinata corals come in various color morphs. Typical shades include green, turquoise, red, orange, brown, and purple, often in multicolored combinations. Many individuals have polyps or their margins that fluoresce strongly under blue aquarium lighting, making the coral a stunning addition to a reef aquarium.
In a reef aquarium, Acanthastrea echinata generally thrives in the lower to mid-level of the tank, where lighting is low to moderate and flow is gentle. The species grows quite slowly but over time forms thick and expanding coral structures on the rock surface.
