Pigmentation: For both males and females, sides are yellow-gold, dorsal surfaces are olive in color, and caudal fins are bright red on the outside and becoming orange at the center.
Occurs in sandy to rocky pools and runs of medium to large rivers, and also in lakes. Spawning occurs along edges and midstream areas of riffles, on pebble, cobble, and gravel substrates (Ref. 49090).
Spawn in groups with between two and seven males and one or two females. Males pose on other side of a female prior to spawning. Brisk vibrations of the dorsal and caudal fins occur during spawning. Gametes are released while males and females rolled over one another. Mean duration of spawning event is 4.4 seconds +/- 0.5 s. Mean duration between spawning events is 22.2 +/- 5.3 mins (Ref. 49090).
