Overview

Not good beginner corals. They need high, often surging current flow to prevent tissue recession at the base of branches, coupled with very good water quality. They tend to turn brown in tanks with even moderate nutrient levels.

Family: Acroporidae

Other common name(s):

Native range:

Maximum length: 200 cm (79 in)

Maximum height: 61 cm (24 in)

Minimum aquarium size: 380 L (100 gal)

Lighting: Bright lighting is essential.

Placement: In full bright light.

Water: Marine 24 °C (75 °F) - 28 °C (82 °F)

Feeding

Zooxanthellate; need microplankton or small particulate organic matter for best growth.

Aquarium Compatibility

No Acropora should be placed in a tank that is less than a year old. These corals need a stable, “mature” tank with excellent water quality, and must be spaced properly to allow for growth.

Special Care

Maintain calcium concentrations at or near 450 ppm. Maintain alkalinity at 3.2 to 4.5 meq/L (9 to 12 dKH). Maintain phosphate at undetectable levels. The aquarium system must be "mature" (stable for at least a year).

Breeding/Propagation

Natural ability to propagate by fragmentation allows clonal aquaculturing. Such clones have undergone physiological adaptation to captivity and survive far better than wild-caught individuals.

Notes

Many of these corals will show different growth forms in different aquariums.
