Acanthastrea
Micromussa lordhowensis, known as Acanthastrea or “Acan”, forms fleshy, round polyps with strong colours. Every specimen is coloured differently. “Master” is a trade name for especially colourful specimens, not a species name. “Asian” refers to its origin in the Asia-Pacific region.
The photo is a blue light photo.
Care
Placement: lower to mid-level in the tank, with some space to other corals, as Acans extend sweeper tentacles at night
Light: low to medium
Flow: low to medium
Feeding: readily takes target feeding such as mysis or fine pellets, which boosts growth and colour
Experience: hardy, good for beginners with an established reef tank
FAQ
What does WYSIWYG mean? “What you see is what you get”: you receive exactly this specimen from the photo.
Are the colours in the photo real? The photo was taken under blue light with white balance.
Do I need to feed the Acanthastrea? It lives from light, but grows noticeably better with target feeding once or twice a week.
How do I place the coral? Place it a little lower or in a shadier spot at first, then move it to full light step by step over one to two weeks.

Care at a glance
Typical requirements of the genus – individual specimens may differ.
Difficulty
Easy to moderate – hardy and adaptable.
Light
Low to moderate; the colours look particularly striking under blue light.
Flow
Low to moderate, so the tissue can fully expand.
Placement
Close to the bottom or in the lower reef area, ideally on flat rocks.
Feeding
Readily takes mysis or pellet food in the evening once the feeding tentacles are out.
Acanthastrea – often sold as Acans and now partly classified as Micromussa – impress with bright, often multicoloured polyps and dense, fleshy tissue. The colonies grow slowly into flat mats and are considered rewarding LPS corals for beginners. Under subdued light and gentle flow they show their most intense colours. Targeted feeding in the evening visibly speeds up growth. Keep some distance from other corals, as Acans extend feeding tentacles at night and can sting neighbouring polyps.
