Brain Corals

Within the LPS group are the so-called Brain corals, which can then be further divided into 'Closed Brains', which normally have a more compact appearance, and 'Open Brains' which tend to expand more and are often fleshier.

Closed Brain corals are very suited to fragging and are quite popular with hobbyists for this very reason. They have a multitude of colors and growth characteristic some being more plating and others more encrusting.

Brain corals have a moderate care level, some can be more challenging than others and their aggressiveness ranges from moderate to high. Brain corals may produce stinging tentacles to attack neighbors, but can also be damaged by more aggressive specimens than themselves.

Lighting requirements range from low to moderate. Some specimens can be prone to bleaching under excess, or sometimes just new, lighting conditions. Acclimate carefully for best results.

They usually prefer a water flow that is more moderate. Excessive flow may prevent these corals from fully expanding. These corals also possess sharp skeletons beneath their tissue, and strong flow may cause the delicate tissue to be torn by the skeleton. This is also the reason these corals should always be allowed to close fully before removing them from the water.

Examples of closed brains include Favia, Favites, Platygyra and many others. There are many color patterns in these corals and they are generally very easy to keep. Occasionally they can be prone to bacterial infections. Dips may be of some help in preventing spread, but usually, they must be cut and the infected portion discarded.
