Acanthastrea corals, commonly known as acan coral or acan lords, are large polyp stony (LPS) corals and one of the most beautifully colored coral species. They come in purple, red, green, blue, orange, brown, rust, pale tan, and pale grey. The family includes many species with different names. And many tout them as one of the easiest LPS corals to grow. Put the two together, and you have the perfect LPS coral – with a few little quirks to manage.
Acan corals are found in the south Pacific, particularly around the Philippines and Hong Kong, in waters down to 30m. Ironically, that seems to be the same depth many waterproof watches are good to. So if you are underwater and still know what time it is, you might see an acan coral. In the ocean, acan coral feed mostly at night. However, they acclimate to diurnal schedules in the aquarium and will happily eat when you feed them.
