Colonies are digitate. Branches are thick, tapering to large dome-shaped axial corallites. Small branchlets or incipient axial corallites usually occur at the base of main branches. Radial corallites are of two sizes, the larger are usually in rows and have thick walls and only slightly increase in size down the sides of branches.
Acroporas require very specific conditions to survive and flourish. They need strong light and good water flow. The water quality should be carefully monitored for Calcium and alkalinity, in addition to the normal parameters of a reef aquarium.
