This LPS is a Lobophyllia - Lobophyllia hemprichii. It prefers to be on rocky substrate, and is irritated by sand granules. In this image, you can see part of it is feeding on Formula One pellet food. It extends short tentacles to assist in retrieving morsels of food. This is another easy coral to care for and does well under Metal Halide lighting. You are looking at only two polyps! Target feeding meaty foods such as Cyclop-Eeze and pieces of krill can take up to 1 hour to ingest, and opportunistic ornamental shrimp may steal the food away. The neighboring Ricordea (in this shot) stung the lobo so keep some space between this coral and others.
