• Four or five scale rows separate the suboculars and the supralabials.

• There is a single row of scales between supralabials and elongate subocular.
• The slackwater darter has a conspicuous dark subocular bar and three prominent saddles.
• There are no suboculars, and the loreal is either very small or absent.
• The suboculars are separated from the supralabials.
• The circumorbital ring includes 2 preoculars, 2 postoculars and 1-2 subocular scales.
• There are 11-14 suboculars.
• It possesses a subocular impression, and 5 to 7 vertical carinae ventrolaterally on its gena.
• The circumorbital ring consists of 2-3 preoculars, 1-2 postoculars and 1-2 suboculars.
• There is an elongate subocular, which is separated from the upper labials by a row of a few small scales.
• There are 14-16 supralabials, which are separated from the suboculars by 3-4 rows of small scales.
• Circumorbital scales towards the ventral or lower side, if any, are called "'subocular "'scales.
• The circumorbital ring consists of 1 2 preocular scales, 1 2 postoculars and 1 2 suboculars that separate the eye from the supralabials.
• The circumorbital ring consists of 2-3 preoculars, 1-2 postoculars, and 1-2 suboculars that separate the eye from the supralabials.
• Care must also be taken when transporting the larger botia, as their subocular spines may puncture the enclosing polyethylene bags that are normally used for this purpose.
• It has been distinguished as having a group of small scales on top of the head, a row of scales that separates the suboculars and the upper labials, as well as a yellow coloration.
• The southern subspecies is distinguished by its smaller size ( adults averaging about 2.4 to 4.4 m in length ), smaller scales on top of the head, and a smaller or absent subocular mark.
• Scalation : dorsal scales in 21 longitudinal rows at midbody ( rarely 23 ); snout length a little more than twice diameter of eye; head above, except for large internasals and supraoculars, covered by small, unequal, smooth scales that are feebly imbricate or juxtaposed; first labial completely separated from subocular or separated by at most a single series of small scales; ventrals : males 164 188, females 167 193; subcaudals : males 50 78, females 44 76.
• Scalation : dorsal scales in 23-25 longitudinal rows at midbody; first upper labial partially or completely fused to nasal; 9-13 upper labials, 1-2 rows of scales separate upper labials from the suboculars; 11-14 scales in a line between supraoculars; supraoculars rarely divided; temporal scales small, strongly keeled; ventral scales : males 153-174, females : 151-180; subcaudals : males 62-79, females 49-61, usually paired, occasionally unpaired shields present among paired series.
