背棘 (總數) : 16 - 18; 背的軟條 (總數) : 10 - 11; 臀棘: 3; 臀鰭軟條: 8 - 9. Diagnosis: 3 lateral spots on the body; supra-pectoral spot 2-2.5 times diameter of supra-anal spot; 12-15 gill rakers on the first ceratobranchial; breeding males with yellow breast, wide yellow marginal band in anal fin and a distinct yellow dorsal fin margin (Ref. 57549).

Territorial males build a bowl-shaped bower beneath and/or adjacent to a rock, 18-42cm in diameter and a 4-7 cm high rim; females occur in schools numbering up to 50 individuals, remaining within 2m above the bottom (Ref. 57549).
