Duncanopsammia axifuga is a large polyp stony coral that comes from the waters around Australia.
Duncanopsammia axifuga from my reef tank.
Duncan corals do need strong light since they are photosynthetic but not nearly as strong a light as small polyped stony corals. They also need to eat some plankton on a regular basis. Otherwise they can be hardy and beautiful aquarium inhabitants.
Unfortunately the specimen shown in the picture has died during a long power blackout.
