Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 4; Rayons mous dorsaux (Total) : 8 - 12; Épines anales: 3; Rayons mous anaux: 5 - 8. Mouth is terminal and upturned. Normally has 12-14 vertical bars along the body, alternating with iridescent interbars of approximately equal width. Sympatric species have head scales or humeral spots and ocular bars.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Are generally cryptic or solitary (Ref. 58006). Inhabit heavily vegetated creeks, sloughs and roadside ditches. Feed on microcrustaceans and other small, benthic invertebrates (Ref. 58006). Oviparous, eggs are found in vegetation or just on the substrate (Ref. 58006).
Eggs are guarded by the male (Ref. 58006).
