What Acropora Tenuis look like

Acropora tenuis is a branching small polyp stony (SPS) coral characterized by its slender, elongated branches that can reach up to 30 centimeters in height. The coral exhibits a delicate, tree-like structure with a high degree of complexity in its branch formation, often displaying a dense arrangement of small, cylindrical corallites that house the polyps. The maximum adult size can vary, but it typically does not exceed 50 centimeters in diameter. Sexual dimorphism is not evident in Acropora tenuis, as both sexes exhibit similar morphological traits. Defensive adaptations include the presence of nematocysts within the polyps, which can deliver a mild sting to deter potential predators. Unique morphological features include its pronounced axial corallites and a smooth texture, which distinguishes it from other Acropora species.

Behavior & temperament

Acropora tenuis is a highly social coral species that thrives in dense colonies, often forming extensive reefs. It exhibits a symbiotic relationship with zooxanthellae, which provides it with essential nutrients through photosynthesis. The polyps extend during the day to maximize light capture, while at night, they retract to minimize predation risk. This species is known for its rapid growth and resilience to environmental changes, although it can be sensitive to fluctuations in water quality. The coral does not exhibit aggressive territorial behavior towards neighboring corals, but it can engage in competition for space and light, utilizing its rapid growth to outcompete slower-growing species.

Diet & feeding

Acropora tenuis primarily derives its nutrients from photosynthesis facilitated by its symbiotic zooxanthellae. In captivity, it requires high-quality light and may benefit from supplemental feeding with planktonic foods or coral-specific supplements to enhance growth and coloration.

Behind the name

The genus name 'Acropora' is derived from the Greek words 'akron' meaning 'top' or 'summit' and 'pora' meaning 'to bear', referring to the coral's branching structure. The species name 'tenuis' is Latin for 'slender' or 'thin', describing the delicate appearance of its branches.
