Galaxea, usually G. fascicularis, a colonial stony coral in the torch and hammer family. Each polyp sits in a small tube-shaped corallite under a centimetre across, ringed with sharp needle-like septa, and the tentacles are usually out by day, so a colony reads as a dense lawn of tiny torch-like polyps. The body is usually green, grey, red or brown with tentacles in a contrasting colour, often tipped white, and those scattered white tips are the starry look the trade name comes from.
Many tiny polyps rather than a few big ones: a Galaxea is a crowd of polyps each under a centimetre, packed into a lawn with pale tips scattered across it, where a Duncan carries one broad disc on each branch. Named Galaxeas (Battlestar, Evergreen, Cyclops and others) are colour selections of the same animal. The real question is space, not care: sweeper tentacles come out at night and sting what they reach, and sources put that reach anywhere from 10cm to over 30cm, so give it open rock. Handle it by the plug, because the skeleton is brittle.
Sandbed or low rock with room around it, and it takes food. Galaxea Coral is beginner to keep at a typical PAR of 50–150 in moderate flow. A typical starting range for this type of coral, not measured on this one.
