Upper sides sometimes with inconspicuous minute dark dots. Dorsal fin dusky, its spinous portion black-edged. Soft dorsal fin with dark spots on each ray. Pectoral and pelvic fins as well as anal fin yellowish to orange. Caudal fin dusky. Inside mouth orange. Mouth large, distinctly oblique, lower jaw projecting. Upper jaw with a pair of large canine-like teeth at tip. Chin without barbels or pores. Snout with 2 marginal pores. Gas bladder with a pair of long, curved, horn-like appendages.
