Platygyra Brain Coral

The Platygyra Brain Coral is a large polyp stony (LPS) coral, and is also referred to as Brain Worm, Maze, Closed Brain, or Bowl Coral. Its genus name, Platygyra, was derived from the Greek words platys (flat) and gyros (wide circle), which describes the maze-like channels in its calcareous skeleton. The Brain Coral colonies are usually massive and either dome-shaped or flattened, with various color shades of green, brown, or gray and contrasting valleys which may be fluorescent under actinic lighting.

It is a semi-aggressive coral that extends sweeper tentacles at night and should be provided with adequate spacing between itself and other corals in the aquarium. The Platygyra Brain Coral is relatively hardy, easy to maintain in the reef aquarium, and makes an excellent candidate for the beginner reef aquarist. It requires a medium light level combined with a medium water movement within the aquarium. For continued good health, it will also require the addition of calcium, strontium, and other trace elements to the water. It produces a large amount of mucus.

It will benefit from additional food in the form of micro-plankton or brine shrimp fed in the evening while its tentacles are visible.
