Piabuco tetra

The Piabuco tetra (*Piabucus dentatus*), also known as the coastal piabucus or chin tetra, is a distinctive freshwater fish native to South America. Its elongated body and unique black marking on the lower jaw make it an appealing choice for aquarists seeking an uncommon addition to their tanks. While it can grow up to 13 cm in length, its peaceful nature and schooling behavior make it suitable for community aquariums when provided with appropriate care. **What makes the Piabuco tetra stand out in an aquarium?** Its unique black marking on the lower jaw and elongated body provide a distinctive appearance that adds visual interest to any tank. **Is the Piabuco tetra suitable for beginners?** Yes, with proper care and attention to its specific needs, it can be a rewarding species for both novice and experienced aquarists. **Care and Environment** To ensure the well-being of the Piabuco tetra, it's essential to replicate its natural habitat within the aquarium. **What is the minimum tank size for a Piabuco tetra?** A tank with a minimum volume of 108 liters (approximately 28.5 US gallons) is recommended to accommodate its active swimming behavior. **What are the ideal water parameters for this species?** Maintain a temperature between 20°C and 25°C (68°F to 77°F), a pH range of 6.0 to 7.5, and water hardness between 1 and 20°H. **How should the tank be set up to mimic its natural environment?** Incorporate a sandy substrate, driftwood branches, and twisted roots to replicate its natural habitat. Adding floating plants can provide shaded areas, as the Piabuco tetra often dwells near the water's surface. Ensure the water is well-oxygenated with moderate flow to simulate the conditions of its native streams. **What should be included in the Piabuco tetra's diet?** In the wild, it feeds on small crustaceans, insects, and other zoobenthos. In captivity, offer a varied diet including high-quality flake foods, live or frozen bloodworms, and other small invertebrates. Interestingly, it may also consume certain types of algae, such as red filamentous algae. **Are there any specific challenges in keeping this species?** While generally hardy, the Piabuco tetra can be sensitive to poor water conditions. Regular water changes and monitoring are essential to maintain optimal health. Additionally, due to its size and active nature, ensure the tank is spacious enough to prevent stress and aggression. **Origin and Habitat** The Piabuco tetra is widespread in coastal waters of northern South America, including Venezuela, Guyana, Suriname, French Guiana, and Brazil, extending southwards to the mouth of the Amazon River. It inhabits low-lying coastal waters such as estuaries and floodplain streams, often found in turbid, silt-laden tributaries and occasionally in brackish conditions. **What type of water bodies does the Piabuco tetra prefer?** It thrives in slow-moving, turbid waters with high silt content, including estuaries and floodplain streams. **Does it inhabit brackish environments?** Yes, the Piabuco tetra can tolerate brackish conditions and is often found in estuarine areas. **How does its natural habitat influence its care in captivity?** Replicating its natural environment by providing a tank with moderate flow, turbid water conditions, and appropriate decor can help reduce stress and promote natural behaviors. **Temperament and Compatibility** The Piabuco tetra is a peaceful, schooling species that thrives when kept in groups. However, due to its size and active nature, careful consideration should be given to tank mates. **Is the Piabuco tetra aggressive?** No, it is generally peaceful but may intimidate smaller, slower-moving fish due to its size and speed. **What are suitable tank mates for this species?** Compatible companions include similarly sized characins, peaceful cichlids, and bottom dwellers like Corydoras or Loricariids. **How many Piabuco tetras should be kept together?** As a shoaling species, it's best to keep them in groups of at least six to promote natural behaviors and reduce stress. **Interesting Facts** The Piabuco tetra is one of the earliest known South American fish in Northern ichthyology, believed to have been recorded first in 1648. Its specific epithet "dentatus" refers to the dense set of 16 teeth present at the end of each mandible. Unlike many tetras, it has been observed consuming certain types of algae, such as red filamentous algae, in addition to its typical diet. **Sources** All information in this article has been gathered from the following reputable sources: - Seriously Fish - Wikipedia - Fishy Wiki
