Common name: Tipped bubblegum coral

General information

The Bubble Coral, Physogyra lichtensteini, is a distinctive and popular species in the reefkeeping hobby known for its unique bubble-like appearance during the day. At night, the coral extends its sweeper tentacles to catch prey. It belongs to the family Euphylliidae and is found in the Indo-Pacific region.

Care

Bubble Corals are relatively hardy and can be a good choice for both novice and experienced aquarists. They require moderate lighting and water flow to thrive. It's important to provide them with enough space as their sweeper tentacles can extend several inches and may damage neighboring corals.

Symbiosis

While not hosting fish or invertebrates like anemones do, Bubble Corals may have a mutualistic relationship with certain types of clownfish, which can occasionally be seen seeking refuge among its tentacles.

Habitat

Physogyra lichtensteini is typically found in reef slopes and lagoons, often in shaded areas or under overhangs to avoid strong light. They are distributed across the Indo-Pacific, from the Red Sea to the western Pacific Ocean.
