The Spaghetti Finger Leather Coral, Sinularia flexibilis, is often referred to as the Flexible Leather Coral, Soft Finger Leather Coral, Rasta Leather Coral, or Thin Finger Leather Coral. It is best recognized from other leathers in the same genus by its flowing long, thin, flexible fingers. Growing on hard substrates such as rubble or dead coral, it grows encrusting colonies with numerous flexible finger projections with polyps that retract when disturbed. Beautiful to watch as it flows in the reef tank. Larger specimens are more "branched" than smaller ones and make an impressive displays. It shows luminous colors of gold, yellow, green, cocoa, and pearl. A fairly fast grower when all it's needs are met, larger specimens are more "branched" than smaller ones and make impressive displays.
Lighting & Flow Requirements
Spaghetti Leather Corals require a medium to high lighting level along with medium to strong water movement. Lighting can be Power compacts, T5's, LED's or even Metal Halides. All lighting can grow Leather Corals as long as the proper level of light is provided. For lighting a coral tank, a 14-20K color spectrum for your bulbs is best for coloration.
Allow approximately two weeks time for the Spaghetti Leather Coral to adjust itself to its new reef aquarium before permanently securing down your coral. Your coral will expand during this period. When deciding placement consider its water flow and lighting needs. Also be certain to leave enough room around your coral that they have plenty of room for growth without infringing on another corals growing room or blocking their lighting.
Diet and Feeding
Leather corals receive the majority of the 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. We do recommend providing supplemental food such as micro-plankton, baby brine shrimp, or foods designed for filter feeding invertebrates.
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.
