Galaxea fascicularis

(Linnaeus, 1767)

Star/Galaxy/Crystal Coral

Likely Reef Tank Suitable

Range: Red Sea, Indo-Pacific Ocean, and Eastern Africa

Natural Environment: Reef environments protected from strong wave action

General Husbandry: Has a temperature range of 74 to 81°F (23 - 27°C). Prefers medium light, moderate water movement, will not tolerate hair algae, and benefits from occasional feedings of zooplankton, such as enriched adult/baby brine shrimp. This is an aggressive photosynthetic stony coral and is not recommended for the beginner. One thing for sure, it should not be placed within six to eight inches of another coral. After the lights go out it extends many long sweepers that can kill or severely sting any animals close by.
