Small groups feed on zooplankton around ledges and the bases of small caves on steep outer reef slopes at depths to about 55 m.


Dorsal fin XII, 12-14; Anal fin II, 12-13; Pectoral fin 16-18; Spiniform caudal-fin rays 2; Tubed lateral-line scales 13-15; Gill rakers 7-9 + 19-22. 
Body depth 1.65-1.85 in SL; Head length 3.0-3.25 in SL; Snout length 3.55-3.75 in head; Orbit diameter 2.6-3.2 in head; Interorbital width 2.5-2.85 in head; caudal peduncle depth 1.8-2.0 in head.


This specific name is from the Latin caudalis (= having a tail) in "reference to the very long caudal filaments; it has the highest caudal concavity of an) species of Chromis (to 1.6 in the SL)".
