Goniastrea

Goniastrea aspera

Verrill, 1905

Honeycomb Coral, Pineapple Coral, Bright Eyes Coral

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Red Sea, Madagascar, Seychelles, Maldives, Japan, East China Sea, and south to Australia.

Natural Environment: Inhabits intertidal zones, shallow protected reef slopes and usually seen at depths between 3 to 50 feet (1 - 15 m).

General Husbandry: Rarely seen in the trade.

As to placement in the aquarium, high areas receiving bright light and swift water movement is best, as this species is often collected in very shallow areas.

Capable of producing its nutritional needs via photosynthesis, yet benefits from once or twice a week feedings of various plankton-like foods, such as Oyster eggs, cyclops, baby brine shrimp, Spirulina, enriched adult brine and mysis shrimp.

Even though its feeding tentacles are usually only displayed at night, it will sometimes display them during daylight hours if it senses food entering the aquarium. I have often used a freeze-dried krill squished between my fingertips in the aquarium water to bring forth the feeding tentacles of various nighttime feeders.

Care should also be taken as to its position in the aquarium in relation to other corals, as this species can send out long sweeper tentacles during evening hours.
