Clavularia Is mistaken at first sight often for Tubipora musica (organ coral). And the Clavularia no steady lime skeleton owns, but a matt-shaped soft Stolon, hence, also type name Stoloniferia. The Stolon is coloured as a rule from reddish to violet, the polyps are most white to radiant green. One should pay attention to it itself the coral enough can spread out and correspond to place leave, then use them this place also "shamelessly".

Zooxanthella/Light , It does not require additional food.
