star polyps


Star Polyps are doing awesome in the 30 gal since the rearrangement.  With more room to grow and lots of TLC these guys have taken off.  The multi-frag rock I am holding is the result of me trimming lobes off the main colonies.  Trimming these lobes is necessarily for their health.   For more on lobe trimming visit the star polyp profile.  I super glued these frags to a rock and after a few weeks, they have fully recovered from the trauma of being handled, cut and glued.  The main colonies have also fully recovered and look better than before the trim–as they have filled in more evenly.  I highly recommend super glue on star polyp frags.  I also used a product called Insta-set to harden the glue faster.  I’ll post on that separately.  

Briareum violaceum

…sometimes known as the “star polyp”, Briareum violaceum is a species of Briareid soft octocoral which can be encountered throughout the Indo-Pacific. Like other  corals B. violaceum is partially predatory and will feed on passing zooplankton which it dispatches with its stinging nematocysts. Briareum violaceum is commonly preyed upon by nudibranchs, especially Phyllodesmium briareum which has evolved to mimic B. violaceum.
