Midnight Aurora Acropora (Acropora sp.)
The Midnight Aurora Acropora is a distinctive SPS coral with deep blue-green branches and subtle glowing highlights around the corallites and growth tips. Under blue reef lighting, it shows a darker, moody base colour, giving it a dramatic reef presence.
 
Key Information
Type: SPS Coral
Care Level: Intermediate to Advanced
Lighting: High
Flow: Medium to High
Placement: Upper reef
 
Description
This Acropora forms upright branching growth with thick stems, rounded tips, and visible raised corallites along the branch surface. The darker blue-green colouration gives the coral a rich, shadowed appearance, while the brighter highlights around the tips and corallites add contrast under reef lighting.
As it matures, the Midnight Aurora Acropora should develop into a compact branching colony with strong structure and subtle colour depth. Its combination of dark reef tones, glowing green accents, and sculpted branch shape makes it a great choice for adding contrast among brighter SPS corals.
 
Water Parameters
Temperature: 24–26°C
Salinity: 1.025
Alkalinity: 7.5–9 dKH
Calcium: 400–450 ppm
 
Feeding
Primarily photosynthetic, but may benefit from occasional supplemental feeding, including:
Amino acids
Fine particulate coral foods
Broadcast coral feeding
 
Compatibility
Reef safe. Allow space from neighbouring corals to prevent shading, crowding, and competition as the colony grows.
 
Notes
Best suited to mature, stable reef aquariums with strong lighting and consistent water parameters. Like most Acropora, the Midnight Aurora Acropora is sensitive to sudden changes in alkalinity, nutrients, lighting, and flow, but will reward stable care with good colouration, branching growth, and polyp extension.
