Dorsal and pectoral fins with black triangles at base, posterior margins white in color. Triangles in this species may be completely solid or composed of closely spaced dots. Black triangles at base of pelvic and anal fins absent or poorly developed. Single black spot may be present at the base of these fins. Adipose fin with white dorsal edge. Both lobes of caudal fin with dark bar from base to tip, posterior margin of fin white. Axillary pore present, mandibular teeth 13-29, 8 pectoral fin rays, eye 44.9-62 % of snout length, premaxillary toothpad uninterrupted, secondary branches on medial mandibular barbel absent, papillae on skin of body absent. Adipose fin short, poorly developed, margin convex. Humeral process narrow in juveniles becoming wider in adults, elongated, granulous, possessing distinct ridge on its ventral margin in young specimens, ridge becoming indistinct in adults, dorsal margin concave, terminating in a sharp point.].
Genus_sexing changed to [First lay the fish in your hand with its head toward your palm and the tail toward your fingers. Hold the dorsal spine between your middle and ring finger so the fish is belly up and you won't get punctured by the sharp fin spines (which hurts - be careful). The genital pore is in a small furrow of tissue (in healthy fish) and will be obstructed by the pelvic fins. Pull down on the tail gently to arch the fish's spine and the pelvic fins will stand and the furrow open to display the genital pore and the anus of the fish. The male has a somewhat ridged genital papillae on which the spermatoduct is on the back side, facing the tail fin. A gravid female will also show an extended papillae but the oviduct is on the ventral side of the papillae. It may also show a little redness if gravid. A thin or emaciated female will have just two pink pores, the oviduct and the anus.] from [First lay the fish in your hand with its head toward your palm and the tail toward your fingers.

General changed to [S. multipunctatus and S. grandiops are most reliably separated by pectoral-fin ray counts with S. mutipunctatus having 1 pectoral fin spine with 8 soft rays and S. grandiops having a count of 1, 7 . The soft pectoral-fin elements (i.e. the rays) are almost always branched (the only exception being the last one or two rays, which are sometimes unbranched) a ray is counted as one at its base before it branches out. Also keep in mind the larger adult size of S. multipunctatus. It appears a southern and northern (at least) tribe exist, with the northern being the ''regular'' form and the southern being generally paler with more spacing between the spots.] from [S. multipunctatus and S. grandiops are most reliably separated by pectoral-fin ray counts with S. mutipunctatus having 1 pectoral fin spine with 8 soft rays and S. grandiops having a count of 1, 7 .

Compatibility changed to [A schooling fish that prefers the company of its own kind. We recommend keeping at least three and ideally five or more S. multipunctatus together.
