Vértebras: 31. Distinguished from congeners by the following combination of characters: body very slender, depth 18.4-23.4% SL: head length 20.6-26.6% SL; snout length 8.1-10.8% SL; upper jaw length 4.3-7.2% SL; mouth subterminal; all fins and lower portion of the head cherry red in adults; caudal fin with broadly blackened distal margin; upper jaw darkly pigmented, appearing as a mustache; lateral stripe, when present, from opercle margin to tip of middle caudal rays; anal fin rays 11(one specimen with 10); lateral line scales 36-41; scales above lateral line 4-5; scales below lateral line 4 (one specimen with 5); premaxillary teeth 4 (one specimen with 3); and dentary teeth 3-4 (Ref. 30270).
Distinct pairs breed on densely grown weedy places (Ref. 205).
