Micromussa spp.

💧Low to Moderate Flow
☀️Low to Moderate Light
⭐Easy to Intermediate Difficulty
Micromussa corals (often still labeled “Acans” after their former placement in the Acanthastrea genus) grow as low, encrusting mats of thick, cushion-like polyps ringed in vivid reds, oranges, greens, and blues. They favor the gentler half of the reef—moderate light, gentle flow—and reward stable conditions with steady, though slower, growth. These LPS corals are a great choice for all reefers—hardy enough for beginners, yet available in a wide range of color morphs that keep experienced collectors hunting for the next piece. Micromussa shares visual similarities with true Acans and Blastomussa, so identification can be tricky: M. lordhowensis sports noticeably larger polyps than M. amakusensis, and compared with Acanthastrea echinata the polyps appear much more inflated.

Micromussa Coral FAQs

Does Micromussa need target feeding?

While Micromussa can meet much of its energy needs from photosynthesis, regular target feeding of small meaty foods such as mysis, brine shrimp, or reef-safe pellets accelerates growth and enhances coloration.

Can Micromussa touch other corals?

Micromussa are known to show aggression and for using their sweeper tentacles against nearby corals. Give adequate (at least 2–3 in. / 5–8 cm) clearance from neighbors to prevent neighbors from getting stung.

Why is my Micromussa receding?

Common causes are excessive light or flow, unstable alkalinity, or harassment by pest organisms (e.g., Acropora-eating flatworms, Amphipods). Check parameters, lower the light intensity it is under, and inspect for pests.

How to Choose a Healthy Micromussa Coral

  • Polyp Inflation & Tissue Health:

    Select pieces with continuous, unbroken flesh wrapping the entire visible skeleton. Any exposed white skeleton or dark, recessed patches can signal recent tissue loss or underlying issues.

  • Healed Cut Edges:

    When purchasing a frag, check that the sawed or chipped edges show a light dusting of new skeleton or thin tissue. A healed rim indicates the coral had time to recover before shipping, reducing transit stress.

  • Clean Skeleton Base:

    Look for a base free of nuisance algae and pests. A clean, off-white skeleton reduces the chance of importing pests and promotes quicker encrustation once the coral is settled.
