Master Grade Rainbow Acanthastrea Echinata

Master Grade Rainbow Acanthastrea Echinata

This Master Grade Rainbow Acanthastrea Echinata earns the “master grade” tag with colouring that doesn’t hold back — a deep teal-green body split by broad, sweeping bands of golden-orange running across the polyp. It’s a large-polyped, fleshy coral, and that scale means the colour pattern reads clearly even from a distance, not just up close.

Acan Echinata is generally a bit more forgiving and faster-growing than some of the smaller-polyped Acan species, making it a solid choice if you want serious visual impact without a fussy coral to manage.

Care basics

• Lighting: Low to moderate. Acans generally prefer the lower end of the tank and can lose colour under overly intense light.
• Flow: Low to moderate. Gentle, indirect flow is best — heavy flow can damage the fleshy polyps.
• Water chemistry: Stable calcium, alkalinity and magnesium matter more than chasing exact numbers.
• Feeding: Not required, but it will take finer coral foods if offered.
• Handling: Generally peaceful, but give it space from more aggressive neighbours.

Supplied on a 3cm frag plug.
