It is distinguished from C. louna by a lower number of gill rakers on first ceratobranchial, 8-11 vs. 13 (Ref. 92878). Further, C. crassa differs from C. bilineata and C. louna by a greater body depth with only a minimal overlap, 40.4-48.4% of standard length vs. 32-2-40.5% and 37.4-42.1% respectively (Ref. 92878). All scales cycloid; 25-27 scales on horizontal line; 18-21 upper lateral line scales; 8-11 lower lateral line scales (Ref. 92878).Colour: Background colour reddish-brown to bluish, chest and belly light brown to whitish with small reddish elements and dorsum darker brown, especially in range of backward slanted, unbranched (not Y-shaped) bars; flank below lateral line more bluish; lower half of head light brown to reddish and upper half of head dark olive-brown; upper lip turquoise and lower lip whitish; a horizontal iridescent turquoise line above anterorostral margin of preopercle; base of pectoral fin whitish edged; iris reddish brown (Ref. 92878). Apparently depending on motivational state, body with five or six black, broad, backward slanted, unbranched (not Y-shaped) bars and a nape band; bluish thin lachrymal stripe extending from lachrymal to jaw angle; black opercular spot, extended into sloping stripe (Ref. 92878). Pectoral fin light yellowish to hyaline, pelvic and anal fin greenish yellow; dorsal fin reddish-brown to yellow-whitiwh edged, black 'tilapia spot' present; caudal fin reddish-brown to yellow, whitish edged (Ref. 92878).
