Bucktooth Tetras - Exodon paradoxus | Live Freshwater Fish

Bucktooth Tetras (Exodon paradoxus) are striking midwater swimmers that inject energy and personality into a tropical freshwater setup. Ideal for experienced hobbyists seeking a dynamic schooling species, they transform a community tank into a constantly shifting, lively display.

Natural habitat

Originating from Colombia and other parts of South America, Bucktooth Tetras inhabit midwater zones of tropical rivers and streams. In the aquarium, they thrive with open water for schooling and ample cover from rocks and plants to break lines of sight and reduce stress.

Adult size

Adult size: Not specified in the provided product details.

Temperament

Temperament: Semi-aggressive. They exhibit energetic schooling behavior and occasional bold interactions with tank mates. Best kept with robust, faster swimmers and in groups to diffuse any one-animal displays.

Tank size

Tank size: Requires a spacious, well-filtered aquarium with rocks and plants to provide cover and break lines of sight. A larger, open-water space supports a healthy school and reduces stress during bursts of activity.

Diet

Diet: Omnivore; readily accepts flakes and pellets, with regular supplementation of live or frozen foods such as brine shrimp or daphnia. A varied diet supports energy for their active midwater lifestyle.

Compatibility

Care level

Care level: Best suited for experienced hobbyists who can manage nutrition, tank mates, and occasional territorial displays. Maintain stable temperatures, good aeration, and consistent water changes to keep them thriving.

Water parameters

Water parameters: Maintain stable tropical conditions with good aeration and regular water changes. Specific numeric ranges aren’t listed in the provided details, so focus on consistent temperature, oxygenation, and filtration to support their active lifestyle.
