Common name: Acropora valida

General information

Acropora valida, commonly known as Valid Acropora, is a species of small polyp stony (SPS) coral renowned for its vibrant colors and branching growth form. It is a popular choice among reef aquarium enthusiasts due to its dynamic appearance and the structural complexity it adds to the reef scape. In the wild, A. valida colonies can exhibit a range of colors, including green, blue, purple, and brown, often with contrasting tips.

Care

Valid Acropora requires stable water conditions and intense lighting to thrive in captivity. They are highly sensitive to changes in water quality, so maintaining optimal levels of calcium, alkalinity, and magnesium is crucial. Strong water flow is also important to mimic their natural reef environment and to keep the coral free from detritus and algae. A. valida is best suited for experienced aquarists who can provide the care and attention needed for SPS corals.

Symbiosis

Like many Acropora species, A. valida forms a symbiotic relationship with zooxanthellae, photosynthetic algae that live within its tissues. This relationship is vital for the coral's survival, as the zooxanthellae provide the coral with nutrients produced through photosynthesis. In return, the coral provides the algae with a protected environment and access to sunlight.

Habitat

Acropora valida is found in the shallow waters of the Indo-Pacific region, including the Great Barrier Reef, the Red Sea, and the central Pacific. They typically inhabit reef slopes and lagoons where they receive ample sunlight and water movement. In the aquarium, replicating these conditions is key to the successful care of A. valida.
