Dragonets-Mandarins:  Notes From Penny:  One of the most spectacular fish kept in the hobby, it can also be one of the most difficult.  These fish spend 99% of their time hunting for live foods like copepods.  Only "reef" tanks set up for more than 8 months (utilizing a sump system) should house these beauties or they have a good chance of starving.  Tanks with attached refugiums are the best!  I am quite successful in getting mine to eat frozen Mysis & Cyclopeez.  If they do, they are as hardy as any other fish.  BUT only if proven eating these foods should one consider putting them in any other type/newer system!    Can be kept in a single male/female pair as they are one of the few marine fish that the sexes can be fairly easy to identify.  The mating dance is a sight to be seen!  Usually occurring at dusk.  Pairs have mated regularly here at AquaCorals...& I'm still waiting for babies.  ;)
