Banded Darter

Banded Darter (Etheostoma zonale)

A small, active, and attractively patterned native darter from the eastern United States. Part of the diverse darter group (over 250 species), the Banded Darter is common in many river systems but remains a favorite among native fish enthusiasts for its subtle beauty, lively behavior in current, and the intensified breeding colors that males display in spring. It makes an excellent addition to native biotope aquariums, riffle tanks, or outdoor setups where its natural foraging and spawning behaviors can be observed.

Key Features

• Maximum Size: Up to 7.8 cm / ~3.1 inches TL (most adults around 5.3 cm).
• Appearance: Slender, elongated body typical of darters, with a series of dark vertical bands or saddles along the sides. During the breeding season (February–May), males develop more vibrant colors and become territorial. Females are generally less colorful and slightly smaller.
• Fin Ray Counts: Typical for the genus (specific counts not detailed on the source page).

Aquarium Care

• Tank Size: Minimum 20–30 gallons for a small group (long tank preferred to allow swimming in current).
• Water Parameters: Cool to subtropical freshwater with current; 50–80°F (10–27°C), preferably 72–76°F (22–24°C) for comfort. Moderate to swift flow, high oxygen, and clean, well-oxygenated water are essential. Use sand, gravel, or cobble substrate with rocks, slabs, and driftwood to create riffle-like conditions. Some live plants or algae growth can provide cover and foraging surfaces.
• Diet: Insectivorous — primarily accepts live or frozen foods such as bloodworm, brine shrimp, daphnia, and small invertebrates. High-quality sinking pellets or flakes formulated for carnivores can supplement the diet.
• Behavior: Active bottom-dweller that forages among rocks and substrate in current. Peaceful with other small, non-aggressive fish but males can be territorial toward each other during breeding. Best kept in groups with plenty of structure. Spawns in spring; adhesive eggs are attached to algae or plants. Sensitive to poor water quality, siltation, and sudden temperature changes.

IUCN Status Least Concern (LC);  common but sensitive to habitat degradation (siltation, pollution, dams).
