Common name: Scroll Coral

General information

Erythrastrea flabellata, commonly known as Scroll Coral, is a small polyp stony (SPS) coral that is appreciated for its unique growth form and vibrant colors. It is characterized by its thin, plating structure that tends to scroll as it grows, creating a fascinating three-dimensional shape that adds depth and interest to any reef aquarium.

Care

Scroll Coral requires moderate to high lighting and strong water flow to thrive in captivity. It is important to maintain stable water parameters, particularly calcium and alkalinity levels, to support its skeletal growth. This coral may benefit from supplemental feeding of planktonic foods, but it also relies on its symbiotic zooxanthellae for nutrition.

Symbiosis

Like many SPS corals, Erythrastrea flabellata hosts zooxanthellae, photosynthetic algae that live within its tissues. This symbiotic relationship allows the coral to receive nutrients from the algae's photosynthesis, which is particularly important in nutrient-poor environments like coral reefs.

Habitat

Scroll Coral is found in the Indo-Pacific region, typically in shallow reef environments where it can receive ample sunlight for its zooxanthellae to photosynthesize effectively. It is often seen on reef slopes and overhangs, where its scrolling plates can grow unobstructed.
