Green Open Brain

Open Brain Corals are one of the more common corals kept in aquaria, and are a good choice for those just

getting started with stony corals. They are usually found with green and/or red coloration with the more common coloration being shades of green. They have a hard skeleton that is covered with fleshy tissues that expand and make the coral look much larger then they actually are. The shape is generally large-lobed and may be flat or dome-shaped. Round or figure-eight-shaped corals are also common.

Care must be taken when placing the coral in the aquarium so that nothing will damage the soft tissue. When placing them in the aquarium place them on the substrate or mid-way in the aquarium where they will receive the most direct light. Open Brain Corals can become shocked and potentially bleached.

Most of the coral's nutrients come from the symbiotic algaes that benefit from this lighting, but supplemental feedings are also beneficial. Open Brain Corals will extend long feeder tentacles at night and should be target fed about an hour after the lighting is off. Some Trachyphyllia have been known to capture larger meaty foods including small fish and invertebrates.
