The slackwater darter feeds on a variety of invertebrates, including larval insects, limpets and isopods (2) (5). Arriving at the breeding grounds in February, reproduction in the slackwater darter is highly dependant on heavy rainfall flooding breeding pools, as well as water temperature, which must be at least 14 degrees Celsius before spawning takes place (4) (5). Fertilised eggs are laid on clumps of plants and aggressively defended by the male parent (5) (6). Once hatched, the juvenile fish grow rapidly, doubling in size between April and June and leaving the breeding areas around May. A short-lived species, the slackwater darter reaches maturity at two years of age, with a life expectancy of only three years (4).
