| Care Description | Acanthastrea as a genus got considerably smaller recently when the Acanthastrea lordhowensis got reclassified as a Micromussa lordhowensis. That leaves the echinata and bowerbanki as the most commonly seen species of Acans in the reef keeping hobby. Acanthastrea bowerbanki have the largest polyps of any Acans. These Acans do not have any special care requirements however they have a strong sting so it is advisable to give them plenty of space in your aquascape. Please see below for additional care tips for Acans. |

General Description
Acanthastrea echinata, commonly known as Cool Runnings Acanthastrea, exhibits a stunning color combination of deep blue base, purple highlights, sky blue, and lime green centers, with bright lime green growth rims. This species belongs to the Acanthastrea genus, which is now primarily represented by the echinata and bowerbanki species in the reef-keeping community. With the recent reclassification, the Acanthastrea lordhowensis is now known as Micromussa lordhowensis. Acanthastrea bowerbanki is notable for having the largest polyps among Acans.
Demands and Hardiness
Acans, including Acanthastrea echinata, do not have specific care requirements but possess strong stings, necessitating ample space in the aquascape to prevent interference. These corals thrive in low to medium-high lighting conditions and can adapt to a wide range of lighting intensities, showcasing color variations based on the light spectrum provided. Moderate water flow is ideal to prevent stress and promote full extension, allowing for optimal feeding opportunities to maintain their health.
Lighting
Acanthastrea corals, such as Acanthastrea echinata, are versatile in their lighting needs, tolerating dim to medium-high light settings. They can be kept under various light sources, from T5 bulbs to low light LEDs. The coloration of these LPS corals undergoes significant changes based on the light quality, impacting aesthetics without affecting the overall health of the coral.
Water Flow
Maintaining a low to medium flow area in the reef display is recommended for Acanthastrea echinata. Excessive water flow can stress the coral, inhibiting full extension. Lower flow rates create more feeding opportunities, which are crucial for the well-being of Acans, including Acanthastrea species.
Feeding
Feeding Acanthastrea, such as Acanthastrea echinata, is essential for long-term health. These corals consume Mysis, Krill, and other medium to large-sized pellets and feeds. Providing a varied diet of frozen fish foods enriched with vitamin additives and highly unsaturated fatty acids is beneficial. Healthy Acans often exhibit feeding tentacles, even during the daytime, indicating good health and nutritional intake.
Propagation
Acanthastrea corals, like Cool Runnings Acanthastrea echinata, have been successfully propagated through fragmentation. While the provided care information pertains to Micromussa lord, similar guidelines can be applied to Acanthastrea species. Successful fragmentation allows for the propagation and expansion of Acanthastrea colonies.
Localization & Habitat
Acanthastrea corals are indigenous to the Indopacific islands, including regions around Fiji, Tonga, Solomon Islands, and the Great Barrier Reef. Specimens of Acanthastrea, like Acanthastrea echinata, are commonly sourced from Australia, reflecting their natural habitat in the Reef's ecosystem.
