Overview
Micromussa lordhowensis (formerly Acanthastrea lordhowensis; family Lobophylliidae), the acan lord, originates from reefs around Lord Howe Island, Australia, and is celebrated as one of the most intensely colored corals in the reef hobby. Dense clusters of large polyps (2–4 cm diameter) display neon combinations of red, green, orange, blue, and purple in striking geometric patterns. Remarkably, these vivid colors are maintained even under low to moderate lighting (50–150 PAR), removing the high-intensity requirement typical of many prized LPS. Gentle indirect flow and standard parameters (24–27°C, KH 8–10, Ca 400–420 ppm) complete the care profile. Weekly target feeding with brine shrimp or small pellets noticeably accelerates growth and color intensity. Sweeper tentacles require adequate spacing from neighbors. Fragging by skeletal division is straightforward. While rare color morphs command premium prices, more accessible variants make Micromussa lordhowensis attainable for hobbyists at all levels.

Natural Spawning and Breeding in LPS Corals | Key Points for Juvenile Coral Rearing and Parental Stock Selection
Natural spawning in LPS (Large Polyp Stony) corals is a biological event triggered by multiple interacting environmental factors. The primary driver is photoperiod: as day length extends from spring into early summer, gonadal development in individual colonies accelerates. Most LPS species reach their spawning season between April and July, with decreasing nighttime illumination and lunar cycles serving as the final spawning triggers...
