Parapriacanthus ransonneti form dense schools in ledges or small caves during the day, dispersing at night to feed on zooplankton. In their schooling habit and general appearance, they resemble some kinds of cardinalfish (Apogonidae). One way they can be distinguished from cardinals is the tendency for the individuals in the school to more more rapidly, and the overall movement of the school seems more fluid and synchronized than that of cardinals. The schools are found somewhat sporadically. We have found them on isolated reefs on the sandy lagoon slope, particularly along the reef between Bigej and Meck Islands, Kwajalein Atoll.
