Acropora

Acropora aculeus

(Dana, 1846)

Branching Plate Coral

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Eastern Africa to the Central Pacific Ocean.

Natural Environment: Inhabits reef slopes and lagoons protected from strong wave action and is seen at depths between 15 to 100 feet (5 - 30 m) where its growth becomes more flattened with depth.

General Husbandry: Usually a bluish green or yellow, yet sometimes seen as blue or brown. Has an upward growth with tips of branches sometimes yellow, lime-green, pale blue or brown.

Even though fully capable of producing all its nutritional needs via photosynthesis, plankton-like foodstuffs fed occasionally may be beneficial/promote quicker growth.

Some forethought needs to be given to newly received specimens as to their initial lighting requirements. Cultured specimens may not have been raised in shallow waters, therefore, begin by placing the specimen where it will receive moderate light, e.g., 250 - 300 PAR. Move to slightly higher PAR levels only after becoming fully acclimated to initial surrounding conditions. Overall, does best with medium to bright light and moderate water movement.
