Similar to other Parapercis species, male P. colias hold territories and their home range increases as the individual grows. Mutch found that they tend to hold large territories rather than but loose territories with small social groups that contain three to five females. Though they hold stable territories, P. colias moves from time to time. In a study, P. colias can move with on average of 2.09±2.12 km, this could potentially be home range shifts. It is reported that P. colias emigrate from coastal to offshore waters in May of each year, this is thought to be a preparation for mating and spawning in early winter.
