The Red Eyed Watermelon Chalice (Echinophyllia aspera) has a bright green surface pigmentation with corallites that are colored bright pink to red and is a colorful addition to any aquarium. This chalice coral sports a green edge around a purple body, resembling a watermelon, hence its name. The color develops when the colony grows to 1 to 2 inches.
Most Chalice Corals will increase the production of mouths (eyes) as they get comfortable with their environment and begin growing.
Chalice Coral are typically an encrusting low rider formation of wavy cups and folds. The middle of the coral can have significantly raised corallites, which can appear as raised round, warty bumps. The flat middle, which is where the oral disc is located, is a raised area 1/2" (1.27 cm) or larger. Some are less dramatically structured with little whorls and slight bumps, while the ends or outer perimeter of the coral are delicate.
