Lord Coral (Micromussa lordhowensis)

About Lord Coral

Sold as "Acan Lord" for years, this is the LPS people pay collector prices for. Large fleshy polyps in striking color combinations; loves to be target-fed and rewards feeding with rapid growth on the sandbed.

Micromussa lordhowensis, previously known as the Acan Lord, is a species of stony coral in the family Lobophylliidae. It is a widespread and common coral with large polyps occurring on shallow reefs in the Indo-Pacific Ocean. It was originally classified under the genus Acanthastrea, and reclassified under the genus Micromussa in 2016.

Notes from the editors

What it looks like. Large, fleshy polyps each up to 1.5 inches across, packed in colonial clusters. Sold for years as "Acan Lord" and still often referenced by that name. Color morphs range from solid greens to multicolor rainbows that command collector prices.

In your tank. Peaceful, no sweepers, slow grower. The polyps are the show — they inflate dramatically during the day and dim somewhat at night. Tankmates that pick at polyps (some hermit crabs, certain wrasses) can damage the colony.

Placement and care. Sandbed or low rockwork. Moderate light (50–150 PAR), gentle flow. Target feeding is part of the standard care recipe — meaty foods or coral pellets directly onto individual polyps once or twice weekly.

Sourcing and feeding. Captive-propagated frags are the universal source ($30–500+, with designer color morphs at the top). Color stability under your lighting is the main variable to monitor in the first months.

Care info is a starting point, not a guarantee. Individual specimens, water chemistry, and tankmate dynamics vary. Verify against multiple sources and adjust to what you observe. See our terms & disclaimers.
