Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Indo-West Pacific Ocean: Red Sea, East Africa, Maldives, Malaysia, Papua New Guinea, Philippines, to the Solomon Islands and Australia.
Natural Environment: Inhabits shallow reef environments and usually seen at depths between 3 to 65 feet (1 - 20 m).
General Husbandry: Somewhat similar to Bubble Coral and is sometimes referred to as "poor man's bubble coral." Yet, there is a dramatic difference with light requirements and water movement between them. This photosynthetic species, which has smaller bubbles, does much better in an area that receives intense light and very good water movement.
Placement must not be near other corals, especially those downstream; as its tentacles are extremely powerful/dangerous to anything they touch!
Can occasionally be fed small pieces of fresh fish flesh/clam/shrimp/baby/adult brine shrimp.
FYI: Colonies form large thick plates covered during daytime with small, grape size bubbles/vesicles, which retract at night when tentacles are displayed and is generally pale grey, sometimes dull green in the wild.
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.
