Kennedy tetra
Introduction
The Kennedy tetra (Astyanax kennedyi) is a lesser-known freshwater fish that has been gaining attention among aquarists for its subtle beauty and manageable care requirements. Native to the upper Amazon basin in Peru, particularly around the city of Iquitos, this species offers a unique addition to community tanks. With a standard length of 4 to 5 cm, Kennedy tetras are suitable for both beginner and intermediate fishkeepers seeking to diversify their aquarium inhabitants.
What makes the Kennedy tetra appealing to aquarists?
Its peaceful nature and adaptability to various tank conditions make it an excellent choice for community aquariums.
Is the Kennedy tetra suitable for beginners?
Yes, due to its hardy nature and straightforward care requirements, it's well-suited for novice fishkeepers.
Does the Kennedy tetra require any special care?
While generally hardy, maintaining stable water parameters and providing a well-structured environment will ensure its optimal health.
Care and Environment
Providing the right environment is crucial for the health and well-being of Kennedy tetras. Here's a comprehensive guide to their care:
What is the minimum tank size for a Kennedy tetra?
A tank with base dimensions of 80 x 30 cm (approximately 72 liters) is sufficient for a small group of Kennedy tetras.
What are the ideal water parameters for Kennedy tetras?
They thrive in temperatures between 26–29°C, with a pH range of 5.5–7.0, and water hardness between 18–215 ppm.
How should the tank be decorated for Kennedy tetras?
Incorporate a sandy substrate, driftwood branches, twisted roots, and tannin-stained water to mimic their natural Amazonian habitat. Adding dried beech or oak leaves can enhance the environment.
For filtration, a system that circulates water at 4–5 times the tank's volume per hour is recommended to maintain water quality.
Lighting should be subdued to replicate the dimly lit waters of their natural environment. Floating plants can help diffuse light and provide additional cover.
As omnivores, Kennedy tetras should be fed a varied diet that includes high-quality flake foods, as well as live or frozen options like daphnia, bloodworms, and brine shrimp.
Regular water changes and monitoring of water parameters are essential to prevent stress and disease.
Origin and Habitat
The Kennedy tetra is endemic to the upper Amazon basin in Peru, particularly around the city of Iquitos. While specific details about its natural habitat are limited, it is likely to inhabit slow-moving rivers and streams with dense vegetation, typical of many Amazonian fish species.
Where is the Kennedy tetra naturally found?
It is native to the upper Amazon basin in Peru, around Iquitos.
What type of environment does the Kennedy tetra prefer?
While specific data is scarce, it likely thrives in slow-moving, vegetation-rich waters common in the Amazon basin.
Are there seasonal variations in their natural habitat?
Detailed information is not available, but many Amazonian fish experience seasonal changes in water levels and flow.
Temperament and Compatibility
Kennedy tetras are generally peaceful and suitable for community tanks with similarly sized, non-aggressive species. However, they may prey on very small fish, so it's advisable to avoid housing them with tiny tank mates.
Are Kennedy tetras schooling fish?
Yes, they exhibit schooling behavior and should be kept in groups to promote natural behavior and reduce stress.
What are suitable tank mates for Kennedy tetras?
Compatible companions include other tetras, non-piscivorous South American cichlids, and catfish from the Callichthyidae and Loricariidae families.
Can Kennedy tetras be aggressive?
They are generally peaceful but may prey on very small fish, so choose tank mates accordingly.
Interesting Facts
While not as commonly found in the aquarium trade, Kennedy tetras can occasionally appear mixed among other species in shipments from Peru.
Is the Kennedy tetra commonly available in pet stores?
No, they are rarely seen for sale but may occasionally be found mixed with other species in shipments from Peru.
Are there any unique behaviors exhibited by Kennedy tetras?
Specific behaviors are not well-documented, but they likely display typical tetra schooling and feeding behaviors.
Has the Kennedy tetra been bred in captivity?
As of current knowledge, breeding in captivity has not been reported.
