Micromussa diminuta | L

Micromussa diminuta is a captivating large polyp stony (LPS) coral from the Mussidae family, renowned for its vibrant colours and intricate polyp formations. This coral is a prized addition to mature reef aquariums, offering both visual appeal and moderate care requirements.

Care and Husbandry

Micromussa diminuta thrives under moderate lighting conditions, such as T5 fluorescents or LED systems, which help maintain its vivid pigmentation without causing stress. It prefers low to moderate water flow to ensure adequate nutrient delivery while preventing tissue damage.

Placement should be on the substrate or lower to middle sections of the aquarium, allowing the coral to expand fully without interference. Adequate spacing from neighbouring corals is essential to prevent aggressive interactions, as Micromussa diminuta can extend sweeper tentacles.

Water Parameters and Compatibility

Maintain stable reef conditions with temperature between 24-27°C, salinity at 1.023-1.025 SG, and calcium levels around 400-450 ppm. This species is generally reef safe with adequate spacing but may exhibit aggression towards nearby corals.

Feeding

While photosynthetic, Micromussa diminuta benefits from supplemental feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods 1-2 times per week to promote growth and vibrant colouration.
