First saddle faint, at dorsal fin origin; other two saddles darker and evenly spaced between dorsal and caudal fins. Ventral portion of body pale, creamcolored, sometimes with dark pigment concentrated along lateral edges and more diffuse pigment across abdomen. Dorsal fin darkly pigmented along base and hyaline distally. Pectoral fin largely hyaline except for dark spots clustered in spear-like submarginal band. Pelvic fin largely hyaline except for faint dark submarginal band. Anal fin with two thin dark transverse bands, one near base and the other near mid-length. Base of caudal fin with dark brown spot extending anteriorly onto caudal peduncle. Remaining caudal fin hyaline except for dark pigment forming blotchy subterminal distal band.
