OTHER COMMON NAMES
German: Gebдnderter Zwergbarsch.
Maximum total length 1.9 in (4.8 cm). White and grayish black, speckled fish with two stripes on the anterior sides of the body. One stripe extends from the mouth through the eye, and the other begins above and behind the eye. Tail and fins are also speckled.
South-central United States south of a line from southern Illinois to North Carolina.
Muddy-bottomed freshwaters, including swamps and other weedy aquatic areas.
Normally solitary; males in limited space will defend their territories against encroachment by other males. Territorial displays include a more intense body coloration, a rapid beating of the tail and pectoral fins, and if necessary, a quick strike at the intruder.
FEEDING ECOLOGY AND DIET
Carnivore; feeds on crustaceans, worms, and other invertebrates.
During breeding season, the male takes on brighter coloration and begins enticing a female to his spawning site by wiggling all his fins in a distinctive pattern. Once a female appears receptive, the male trembles and “points” to the site with his snout, and then gently prods the female. Nest building may or may not occur, perhaps depending on the suitability of the substrate. Relatively little is known of its
in the wild.
Not listed by the IUCN.
SIGNIFICANCE TO HUMANS
Of minor importance to the pet trade, also important as indicator species of environmental quality.
