A. millepora corals are unique in their scaly appearance when the polyps are retracted. These corals can take many different growth forms depending on the water movement and light that it receives, but will typically grow in a clustered form. If provided with enough alternating current, they will show their very long, hairy polyps.
They will thrive in a variety of lighting conditions, ranging from power compacts, VHO and T-5, up to the more intense metal halides. Alter their position in the aquarium depending on the lighting, and provide at least 3 watts per gallon using one of the lighting systems mentioned above. For continued good health, it will require the addition of supplemental calcium, strontium, and other trace elements to the water.
It will also benefit from additional food fed weekly in the form of micro-plankton or foods designed for filter feeding invertebrates.
