BUCKTOOTH TETRAS (EXODON TETRA)

Bucktooth Tetras (Exodon Tetra) Care Guide

The Bucktooth Tetra, scientifically known as Exodon paradoxus, is a striking freshwater fish popular among aquarium enthusiasts for its unique appearance and active behavior. Known for its distinctive sharp teeth and slender body, this species can add both character and excitement to a community tank when cared for properly.

Size and Appearance

Bucktooth Tetras typically grow to about 3 inches (7.5 cm) in length. Their elongated, silvery bodies are accented by sharp, protruding teeth that give them their common name. This distinctive feature is not just for show; it plays a role in their feeding habits and social interactions.

Temperament and Behavior

These tetras are semi-aggressive and highly active swimmers. They exhibit a unique behavior of nipping at the fins of slower-moving or long-finned tank mates, so carefully selecting compatible species is essential. Bucktooth Tetras thrive best in groups of six or more, which helps diffuse aggression and encourages natural schooling behavior.

Tank Size and Setup

A minimum tank size of 30 gallons is recommended to accommodate a small school of Bucktooth Tetras. They require plenty of swimming space complemented by dense plantings and hiding spots to mimic their natural habitat. Driftwood and rocks can be added to create a comfortable environment that reduces stress and promotes natural behaviors.

Water Parameters

• Temperature: 72°F to 79°F (22°C to 26°C)
• pH Level: 6.0 to 7.5
• Water Hardness: Soft to moderately hard (2–15 dGH)

Maintaining stable water conditions and regular water changes are crucial to keeping these sensitive fish healthy.

Diet and Feeding

Bucktooth Tetras are omnivorous with a preference for live and meaty foods. Their sharp teeth allow them to hunt smaller fish and insects in the wild. In captivity, a varied diet including high-quality flakes, pellets, live or frozen bloodworms, brine shrimp, and daphnia will keep them healthy and vibrant. Feeding small amounts two to three times a day is ideal to prevent overfeeding.

Compatibility with Other Fish

Because of their fin-nipping tendencies, Bucktooth Tetras are best kept with fast-moving or robust tank mates that can tolerate their behavior. Avoid slow-moving or long-finned fish such as angelfish or bettas. Suitable companions include other active tetras, barbs, danios, and larger catfish species.
