Seafoam blue green trachyphyllia coral ultra
One of the most common corals offered to reef aquarists is the open brain coral, Trachyphyllia geoffroyi, which is an exceptionally hardy species. These most commonly come in various mixes of fluorescent shades of green and red, with some being almost entirely green, others being almost entirely red, and many that are something in between. And, when it comes to common names, specimens that are predominantly green are accordingly called green open brains, while those that are predominantly red are called red open brains. They can also come in shades and mixes of brownish, pinkish, or even bluish, colors, as well. So, most of them are quite attractive.
