Description
Blue King Tetra (Boehlkea fredcochui)
Introduction:
The Blue King Tetra (Boehlkea fredcochui) is a striking freshwater species known for its shimmering blue coloration and active swimming behavior. Originating from South American river basins, this small schooling fish is an excellent addition to community tanks, providing constant movement and vibrant color.
1. Natural Habitat and Behavior
Native to fast-flowing rivers and streams in South America, the Blue King Tetra thrives in well-oxygenated waters with dense vegetation. They are highly active, shoaling fish that require groups of at least six to feel secure and display their best coloration.
2. Aquarium Setup
- Tank size: A minimum of 20 gallons, though larger tanks allow for a more dynamic school.
- Substrate: Fine gravel or sand with dark tones to enhance their color.
- Decor: Live plants, driftwood, and rock formations create a natural environment.
- Water conditions: pH 6.0-7.5, temperature 72°F-78°F, moderate flow.
- Lighting: Moderate lighting enhances their iridescent blue hue.
3. Diet and Feeding
Blue King Tetras are omnivores and thrive on a varied diet of high-quality flakes, micro pellets, and frozen or live foods such as daphnia and bloodworms. Feeding twice daily with a mix of protein and plant-based food helps maintain their health and coloration.
4. Compatibility with Other Fish
This species is peaceful but energetic, making them ideal for community tanks with similarly sized fish. Good tank mates include other tetras, rasboras, Corydoras catfish, and peaceful dwarf cichlids. Avoid slow-moving or long-finned fish, as their fast swimming may cause stress.
5. Common Challenges and Tips
- Schooling Needs: Keeping them in groups of six or more reduces stress and encourages natural behavior.
- Water Quality: Regular water changes and good filtration are crucial to maintaining their health.
- Tank Mates: Avoid aggressive species that may outcompete them for food or harass them.
Conclusion
The Blue King Tetra (Boehlkea fredcochui) is an excellent choice for aquarists looking to add a splash of blue and constant activity to their aquariums. With proper care, a well-maintained environment, and a suitable school, these tetras will thrive and enhance any community setup.
