Ultra Red Acan Lord

About this coral

Ultra Red Acan Lord is a colorful LPS (large polyp stony) coral commonly sold under the “acan” umbrella (often referred to as acan/acan lord corals). In a reef tank, it’s valued for its fleshy, expandable polyps and its ability to do well when given stable water conditions, appropriate lighting, and regular feeding alongside photosynthesis-based growth.

Features:

• LPS “acan” coral type with fleshy polyps that extend for feeding and can help “wake up” with good tank conditions.
• Moderate lighting is generally recommended for acan-type corals, helping support photosynthesis without excessive intensity.
• Moderate, gentle water movement supports polyp expansion and food capture.
• Target feeding can improve performance; acan-type corals benefit from small meaty foods offered to the feeding tentacles.
• Best kept in a spot where it can feed without being knocked around by strong currents or competing for space.
• Like many LPS corals, it generally does best with stable, well-maintained water chemistry rather than frequent swings.
