Swamp Darter

The Swamp Darter is one of the most habitat-tolerant darters in eastern North America, occurring in a variety of sluggish, vegetated, often acidic coastal-plain waters. Unlike most darters, it does not require strong current and is comfortable in still or slowly moving water — making it more adaptable to aquarium conditions.

Males are subtly patterned with brown-and-olive mottling and small blue-green iridescent spots between the dark saddle marks. The species rests motionless on plant leaves or detritus, darting suddenly to capture tiny prey.

The Swamp Darter is an ideal entry-level darter for aquarists interested in North American native fish, as its still-water tolerance removes the need for powerful current equipment.

Water: 8–20°C, pH 6.0–7.5, GH 2–12; tolerates still, slightly acidic water; good oxygenation appreciated. Tank: minimum 40 L, dense aquatic plants, leaf litter, fine sand substrate. Feeding: carnivore — live/frozen micro-worm, baby brine shrimp, daphnia, cyclops. Breeding: deposits eggs on plant leaves; male guards briefly; rarely documented in captivity. Compatibility: peaceful; compatible with small, non-boisterous North American native fish.
