Common Name: slim minnow
Taxonomy: available through 
Identification: Robison and Buchanan (1988); Page and Burr (1991); Pflieger (1997). A name used in some of the earlier literature is Ceratichthys tenellus (e.g., Hubbs and Black 1947). Two subspecies are recognized, the western slim minnow Pimephales tenellus tenellus and the eastern slim minnow Pimephales tenellus parviceps (Page and Burr 1991; Pflieger 1997; Gilbert 1998).
Size: 7 cm.
Native Range: Southern Missouri, eastern Kansas, Arkansas, and northeastern Oklahoma (Page and Burr 1991). Restricted to the Ozarkian areas of the above named states, in Red and Arkansas river drainages and independent tributaries of Mississippi River (Lee et al. 1980 et seq.).
Nonindigenous Occurrences: This species was recorded from a pond in the Osage River system (Missouri River drainage) in Kansas (Hubbs and Black 1947).
Means of Introduction: Unknown, possible bait bucket release or stock contaminant.
Status: Reported from Kansas.
Impact of Introduction: Unknown.
Remarks: Hubbs and Black (1947) noted the taking of a single specimen of "Ceratichthys perspicuus" from a pond in the Osage River system in Kansas. In addition, they reported the finding of at least one specimen of "Ceratichthys tenellus" from the same station and stated that it also doubtless represented an introduction from the Neosho River system. In their account for "Ceratichthys perspicuus," Hubbs and Black (1947) identified the station as Jones Pond, Coffee County. That water body was apparently an artificial impoundment, probably a farm pond. In reference to the single record of Hubbs and Black (1947), Cross (1967) stated that he had never obtained Pimephales tenellus from the Osage drainage.
