Acan Brain Coral 4.5″ WYSIWYG
The Acan Brain Coral wakes up tired reef aquariums with a jolt of exhilarating orange or red coloration. This color morph of the popular large polyp stony (LPS) coral demonstrates the exceptional range of vivid coloration displayed by Acanthastrea echinata. The Acan Brain Coral boasts coloration inspired by pop-culture featuring contrasting gradients of teal, orange, and sometimes red. Intense pops of caffeine-induced coloration transforms barren regions of your substrate and other lack-luster regions of the reef aquarium with visual excitement.
Acanthastrea generally have large corallites (8-15mm) with small teeth or lobes on their septa, as well as well-developed columellae. In the wild, they’re found mostly in shallow water to about 20m, often in protected areas like lagoons.

The Acan Brain Coral transformed my tank after months of dullness. The orange and teal gradients are striking and add a dynamic look. I’ve had it for three months and it’s thriving with proper lighting and flow.

Great color contrast in my reef setup. It’s not the fastest grower, but the visual impact is worth it. I keep it in a well-lit corner with moderate water movement.

Installed it last month and it’s already showing vibrant coloration. The coral looks more natural in the tank and brings a lot of energy to the display. Very satisfied with the purchase.
