Chromis enchrysurus inhabits steep slopes and outer reef sides and occurs in small groups near small outcrops
Adults:
Their upper half of the head and body and spiny dorsal fin are dark gray-brown, the lower parts and base of the tail are white, giving an abrupt separation between these two color zones.
A purplish-blue stripe extends from the upper lip over the upper eye margin to below the anterior 1/3 of the dorsal fin, and the soft dorsal and caudal fins and the outer three-quarters of the anal fin are yellow.
In juvenile fish, the upper three-quarters of the head and body are dark blue-gray, blending into white below, the blue lines are more pronounced, the fin colors are similar, and the pelvis is yellow.
Emery and Smith-Vaniz (1982) redescribed Chromis enchrysurus and analyzed morphological variation among populations of the species.
They noted that Chromis enchrysurus occasionally has white instead of yellow on the caudal, pelvic, and anal fins and the posterior portion of the dorsal fins, and that the species comprises either two or three populations (Bermuda, Brazil, and Caribbean plus the United States) that differ morphologically.
Note: Chromis enchrysurus is closely related to Chromis cf enchrysura but genetically distinct, this species has a different color pattern and geographic range.
