背面の脊椎 (合計) : 15 - 16; 背鰭 (合計) : 10 - 11; 肛門の骨: 3; 臀鰭: 8. Diagnosis: lower pharyngeal jaw robust, with a large, non-heart-shaped but triangular dentigerous plate, covered with stout, sparsely arrayed teeth; oral dentition coarse; outer row teeth stout bicuspids; anterior gill rakers not markedly reduced in size (Ref. 26738, 81260). Snout acute (Ref. 81260). Ventral margin of lower lip smooth; gill rakers (12-14) stout and fleshy with a crenulate median membrane connecting outer and inner row rakers (Ref. 26738, 81260). Ratio of lower jaw length to lower jaw width usually < 1 (Ref. 81260). Upper jaw with 2-4, in lower jaw with 2-3 inner tooth rows (Ref. 26738, 81260).
Feeds mainly on freshwater sponges, but also filamentous algae, phytoplankton and small amounts of insects (Ref. 52307). Substrate brooder (Ref. 52307, 81260). Probably pair-bonding, with both parents guarding the brood (Ref. 52307).
