Open Brain Coral - Red
Open Brain Coral - Red
Trachyphyllia geoffroyi

This sand dwelling organism will sting other organisms near it, so give it space. Open Brain or Pacific Rose Coral is amongst the easiest to care for, most appropriate true or stony coral species available to marine aquarists. Given selection of initially healthy specimens, moderate light, water movement and decent water quality this it ranks near the top in terms of hardiness. Open Brain Coral has large polyps with a mantle that can be expanded more than three times the size of its skeleton during the day. Generally this is a nocturnal feeder, producing rows of tentacles to capture prey by the dark of night. You can see the numerous mouths in the colonies valleys at this time. Trachyphyllia are "secondarily free-living", starting off as single attached polyps, annealed to a hard substrate, and later breaking off, mostly found on sand to muddy bottoms... their color varying with depth, turbidity of water. Color variation abound in Trachyphyllia, with pink to reddish to tan to brownish to gray to greenish, blue... even multi-streaked ones with highlights. Adapting to a wide range of lighting, water motion and quality, Trachyphyllia is an ideal "starter" or "beginner" stony coral; likely the hardiest of stony/true coral species in aquarium use. Happily it is an abundant/common, easy to collect species in the wild with a distribution range matching its usefulness to aquarists. This specimen requires being directly on the sand. It will puff up it's polyp to shift itself to better recieve the light and flow. Failure to allow it to do this will result in a stressed coral that will likely die.

Behavior: The Trachyphyllia geoffroyi is generally semi-aggressive toward other tankmates.
