Micromussa, formerly known as Acanthastrea, is a popular large polyp stony (LPS) coral in the reef aquarium hobby, known for its vibrant colors and relative hardiness. Two commonly seen species are Micromussa lordhowensis and Micromussa amakusensis, distinguished by polyp size. They thrive in low to moderate light and moderate water flow, benefit from target feeding, and can be aggressive, so they need space from other corals.
Key characteristics of Micromussa corals:
-
Colony Formation:
Micromussa forms massive, cerioid (closely packed, adjoining corallites) colonies.
-
Corallites:
The individual corallites (the structures housing the polyps) are typically circular or angular, and vary in size depending on the species. For example, M. lordhowensis has larger corallites than M. amakusensis.
-
Septa:
The septa (walls within the corallites) are thick and beaded or toothed.
-
Columella:
The columella (a central structure within the corallite) is typically poorly developed.
-
Fleshy Tissue:
Micromussa colonies have a thick fleshy mantle, sometimes covered with fine papillae (small projections).
-
Color:
Micromussa corals exhibit a wide range of colors, including red, orange, purple, blue, and green, often with contrasting colors in the corallite walls and fleshy tissue.
-
Aggression:
Micromussa corals can be aggressive, extending sweeper tentacles to sting neighboring corals.
Care requirements:
-
Lighting:
Micromussa corals generally prefer low to moderate light, as intense lighting can cause color changes.
-
Water Flow:
Moderate water flow is recommended, enough to prevent detritus buildup but not so strong as to damage the coral or prevent polyp extension.
-
Feeding:
Micromussa corals readily accept meaty foods like mysis shrimp and brine shrimp, and can also be target-fed with small pellets.
-
Space:
Due to their aggressive nature, Micromussa corals need to be provided with adequate space away from other corals.
In summary, Micromussa corals are attractive, relatively hardy additions to reef aquariums, requiring specific lighting, flow, and feeding, as well as careful consideration of their aggressive tendencies.
