Frosty Tenuis Acropora

About this coral

Frosty Tenuis Acropora is an SPS branching coral in the Acropora tenuis group, popular for its compact, table-branching look and its strong dependence on intense, consistent reef-style conditions. In an aquarium, it’s used as a centerpiece SPS that benefits from being placed where it can receive strong lighting and turbulent, alternating water movement while you maintain stable reef chemistry for long-term survival and health.

Features:

• SPS (small polyp stony) branching coral that generally does best in established, stable reef aquariums
• Prefers moderate to high light and strong, alternating water current for healthy tissue extension
• Tenuis-style growth forms are often described as “tabling”/compact branching, making good use of rockwork ledges or mid-to-upper placement
• Benefits from consistent carbonate chemistry (alkalinity, calcium, magnesium) to support calcification
• Typically treated as a Moderate care-level coral in aquarium trade references, making stability more important than one-off “perfect” numbers
• Often responds well when fed indirectly through the system’s water quality and routine particulate/pelagic foods (when your overall husbandry supports it)
