Scientific Name: Aphyocharax anisitsi
The Bloodfin Tetra will grow to a size of one and three-quarters to two inches. Male Bloodfins can be identified by the small hook located on the anal fin. They live to an average age of 10 years.
Bloodfin Tetras will survive in water with a temperature range from 64 to 84 degrees Fahrenheit. They like slightly acidic water, with a pH between six and eight. They eat flake and freeze dried foods, and should occasionally be frozen foods, such as: daphania, plankton, beef heart, brine shrimp, glass worms and blood worms.
The Bloodfin Tetra is an easy fish to breed. Females will lay between 300 and 500 eggs, in between plant areas. Once spawning has occurred, the parent fish should be removed from the tank. Bloodfin Tetras are independent at birth.
Fresh water fish
An excellent community fish, the Bloodfin Tetra makes a great addition to any populated aquarium. Bloodfin Tetras, or Aphyocharax anisitsi, are small, colorful, easy to care for, and have a long life span. They are ideal for beginners.
The Bloodfin Tetra is a friendly fish. It is not aggressive, and will coexist most other fish. They should be kept in schools. They generally swim in the middle of the tank, though they have been known to swim at the top and bottom as well. It does not need a heated tank, but their colors are not as brilliant in cold water. Bloodfin Tetras are happiest in large aquariums, with moderate amounts of rocks, live plants and driftwood. They especially like valisneria and sagittaria plants, located at the borders of the tank.
Bloodfin Tetras are originally from the subtropical Parana River in Argentina. However, they are widely available.
