Here is a pic to show you how one particular coral grows and multiplies. This is caulastrea curvata, or, trumpet coral. It is a large polyped stony coral (LPS) which contain the symbiotic photosynthetic algae zooxanthellae. In the lower central portion of the pic, you can see one coral head 'pinching off' or dividing to form another polyp. Also visible is a nice shot of sweeper tentacles.
Although most photosynthetic corals will survive under the appropriate lighting, almost all of them will sweep the ocean currents in the natural setting to capture food. Although I beg to differ from commercial websites that say your corals will benefit "along with the addition of calcium, strontium, and other trace elements to the water. " (calcium, yes), I DO believe that they benefit from the feeding of plankton and other meaty foods.
Here is another coral that has a mechanism for 'eating'. This is a closeup shot of an orange plate coral (fungia sp). Note the slit in the middle of the coral. At night, the short tentacles that you see in this picture, when coming in contact with food, will sweep the food inwards toward the oral disc and the food will be incredibly pulled into the center of the coral and disappear.
Don't forget to feed your corals. SH
