The flower corals (Euphyllia) are not as common as Fungia, but can be quite beautiful. They form a maze of flat plates that stick up vertically 10-20 centimeters and cover an area 50 centimeters or even much more in diameter. These corals have long, colorful tentacles, which they extend during the day. Euphyllia tolerates turbid water, and can be found growing on patch reefs in back reef channels.

The very bright orange polyps of the coral Tubastrea (or the similar Dendrophyllia) can be seen in small clusters, usually in low-light areas such as deep on the reef or under overhangs. These finger-sized polyps can easily be mistaken for anemones. They are true scleractinian corals, however, and secrete a very fragile internal skeleton. Tubastrea contains no zooxanthellae and receives all its nutrition by capturing plankton. At night, you can watch the polyps feeding by using your light to attract the plankton within reach of the polyps' tentacles. (If your light is very bright, shade it so the polyps won't retract.)
