6 x Black Widow Tetra: A Dramatic and Hardy Aquarium Star Scientific Name: Gymnocorymbus ternetzi

Product Description:

Scientific and Common Names:
The 6 x Black Widow Tetra, scientifically known as Gymnocorymbus ternetzi, is a vibrant and eye-catching South American Tetra species. Commonly referred to as Black Widow Tetras, these fish are known for their striking appearance and hardy nature.

Habitat:
Black Widow Tetras are native to the rivers and streams of South America, particularly in the Amazon River basin. They thrive in warm, soft, and slightly acidic water conditions, mimicking their natural habitat.

Tank Setup:
To provide a suitable environment for the Black Widow Tetras, it is recommended to have a well-planted aquarium with plenty of hiding spots and open swimming areas. A tank size of at least 20 gallons is ideal for a group of six tetras. It is important to maintain stable water parameters, including a temperature range of 72-82°F (22-28°C) and a pH level between 6.0 and 7.5.

Diet and Nutrition:
Black Widow Tetras are omnivorous and have a diverse diet. They primarily feed on high-quality flake or pellet food, but their diet should also be supplemented with live or frozen foods such as brine shrimp, bloodworms, and daphnia. Providing a varied diet ensures their nutritional needs are met and enhances their vibrant colors.

Size and Growth Rate:
These tetras have a moderate growth rate and can reach a size of approximately 2 inches (5 cm) within a year. They are considered a small-sized fish, making them suitable for various aquarium sizes.

Behavioral Traits:
Black Widow Tetras are known for their active and lively nature. They are schooling fish, so it is recommended to keep them in groups of six or more to promote their natural behavior. They are peaceful towards other fish species but may display some fin-nipping behavior towards their own kind if kept in smaller groups.

Care Level:
These tetras are relatively easy to care for, making them suitable for both beginner and experienced fishkeepers. They are hardy and can adapt well to different water conditions, as long as the basic requirements are met.

Breeding and Reproduction:
Black Widow Tetras are egg-layers and can be bred in a separate breeding tank. To encourage spawning, provide them with soft, slightly acidic water and a diet rich in protein. The female tetras will scatter their eggs among plants, and the parents should be removed after spawning to prevent them from eating the eggs. The eggs will hatch within 24-48 hours, and the fry can be fed with infusoria or commercially available fry food.

Health and Disease Prevention:
Maintaining good water quality and providing a balanced diet are crucial for the overall health of Black Widow Tetras. Regular water changes, proper filtration, and monitoring water parameters are essential. Quarantining new fish before introducing them to the main tank can help prevent the spread of diseases.

Optimal Water Conditions:
– Temperature: 72-82°F (22-28°C)
– pH Level: 6.0-7.5
– Water Hardness: Soft to slightly hard water (4-12 dGH)

Lifespan:
With proper care, Black Widow Tetras can live for 3-5 years. Providing a suitable environment, a balanced diet, and regular maintenance will contribute to their longevity.
