Eschmeyer's Scorpionfish (Rhinopias eschmeyeri) may be a junior synonym of Rhinopias frondosa as both forms are often seen together. This seems to be backed up by video footage showing the paddle-flap and weedy forms of Rhinopias  mating at Alor in Indonesia. Perhaps they are male and female of the same species.
