Lighting & Flow Requirements
The Green Finger Leather Coral requires a moderate water flow and likes strong, direct lighting. Lighting can be Power compacts, T5's, LED's, Metal Halides or any combination. For lighting spectrum use between a 14-20K color spectrum for your bulbs for best coral coloration.
Diet and Feeding
Although Finger Leather Corals receive a portion of their nutritional requirements through the process of photosynthesis, which simply means their lighting creates symbiotic algae called zooxanthellae in the body of the leather coral which provides its nutrition, the Finger Leather Coral relies less on the process of photosynthesis, and depends more on obtaining outside food. Microplankton, marine snow, and dissolved materials should make up the bulk of the diet.
Most leather corals go through a natural process of cleansing, once in a while. Leather corals will shrink smaller and the outer skin will look strange as it sloth's itself off, shedding the top layer as it cleanses itself. Leathers may remain closed from just a few days to even a week or longer depending on the aquarium flow and other conditions, but they will reopen larger and even more beautiful than they were before.
