Solenostomus paradoxus the ornate ghost pipefish or harlequin ghost pipefish. They reach a maximum length of 12 cm. They vary in color from red or yellow to black. Juveniles are pelagic (open Ocean) and almost completely transparent to protect themselves better from predators. Once Harlequin Ghostpipe Fish become mature they’ll look for a reef and a coral they like and will change color towards the coral.
