Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Indo-West Pacific Ocean: Malaysia, Papua New Guinea, Philippines, to the Solomon Islands.
Natural Environment: Inhabits turbid or sheltered reef environments and usually seen at depths between 25 to 100 feet (8 - 30 m).
General Husbandry: Occasionally seen in the trade.
Best placed on bottom areas receiving medium indirect light and gentle water movement.
Even though capable of producing all its nutritional needs via photosynthesis/Nutrient absorption, micro plankton-like foodstuffs fed occasionally 'may' be beneficial/promote quicker growth.
Care should be taken as to its position in the aquarium, as this species is basically defenseless against other corals, even those not overly aggressive.
FYI: Colonies may form large meandering, interconnected thin walled growths that are very fragile, and usually cream to pale green.
Only species in the genus. Close relative to the genus Physogyra.
Always select a specimen that does not have any kind of alga growth on any of its exposed skeleton surface, as it will cause the tissue to recede, usually leading to the animals demise sooner or later.
Do not remove a specimen with highly inflated tissue areas from the water as the weight of the water in the polyps may damage or tear its flesh lose from its skeleton material. Gently shake the specimen and allow the flesh to retract somewhat before removing.
