Rainbow Acan Echinata Coral Frag The Rainbow Acan Echinata is a high-impact LPS coral prized for its aggressive skeletal texture and intense, multi-coloured patterning. Featuring bold combinations of reds, greens, blues, purples, and metallic highlights, this coral delivers dramatic contrast and unmistakable presence, making it a true standout in any reef system. More assertive in both appearance and temperament than standard Acans, Rainbow Acan Echinata is best suited to stable, mature reefs where its colour and structure can be fully appreciated. Natural Habitat & Distribution Acan Echinata corals are found across shaded reef slopes in the Indo-Pacific, including: IndonesiaAustraliaFijiThe Philippines They naturally inhabit deeper or protected reef zones where lighting is lower and water movement is gentle. A Brief History Echinatas have long been regarded as one of the more aggressive and visually striking members of the Acan family. Their thick tissue, sharp skeletal ridges, and bold colouration set them apart, with rainbow morphs becoming especially desirable as modern lighting enhanced fluorescence and contrast. Appearance & Growth Classed as an LPS (Large Polyp Stony) coral, Rainbow Acan Echinata features: Thick, fleshy tissue over sharp skeletal ridgesIntense multi-colour contrastStrong fluorescence under blue lightingCompact but bold growth form Growth is slow to moderate, with stability and colour improving over time in well-maintained systems. Placement & Lighting Rainbow Acan Echinata performs best under lower lighting conditions. Lighting: Low to MediumBest placed on the sand bed or lower rockworkExcessive light may cause tissue recession or colour loss Flow Requirements Provide low to moderate, indirect flow. Enough movement to keep tissue cleanAvoid strong or direct flow that may damage tissue Water Chemistry Stable reef parameters are essential for long-term success. Maintain consistent levels of: CalciumAlkalinityMagnesium Along with stable salinity and temperature. Regular testing and water changes are recommended. Feeding This coral responds well to feeding and benefits from regular target feeding: Mysis shrimpBrine shrimpLPS pellets or powdered coral foods Feeding 1–2 times per week can support growth and enhance colour intensity. Temperament & Spacing Acan Echinata is considered aggressive compared to other Acans. Allow generous spacing from neighbouring coralsAvoid placing near delicate or passive species Frag Size & Natural Variation Frag Size: Approx. 1 inch Colour balance and intensity may vary slightly between frags and depending on tank conditions.
