Water Parameters

Water parameters are the key environmental factors that Aquarists must consider in order to maintain the health of their Bloodfin Tetras. The three most important factors are pH, hardness, and temperature.

pH: 

The pH of your aquarium water is critical to the health of your Bloodfin Tetras. A pH that is too high or too low can cause stress and illness. The ideal pH for Bloodfin Tetras is between 6.5 and 7.5.

Hardness:

As with most fish, the Bloodfin Tetra is best kept with other fish that share similar water conditions and temperament. Although they are a peaceful fish, they can be nippy towards slower moving fish or those with long fins. They are also known to harass other fish that are much smaller than them. For these reasons, it is best to keep them with other peaceful, fast moving fish that are similar in size. Some recommended tank mates for Bloodfin Tetras include:

  • Neon Tetras
  • Cardinal Tetras
  • Pristella Tetras

  • White Skirt Tetras

  • Lemon Tetras

Breeding

Like most tetras, Bloodfins are easy to breed in the home aquarium. They are an egg-laying species, and will typically lay their eggs on plants or other surfaces near the surface of the water. After the eggs have been laid, the parents should be removed from the breeding tank to prevent them from eating the eggs.

The eggs will hatch in 24-48 hours, and the fry will be free-swimming a few days after that. They can be fed newly-hatched brine shrimp or other small live foods until they are large enough to eat flakes or pellets.

If you want to maximize your chances of success, it is best to set up a dedicated breeding tank for your Bloodfins. This tank should be well-planted, with plenty of hiding places for the fry. A small air-powered sponge filter is all that is needed for filtration.

The water in the breeding tank should be slightly acidic, with a pH of 6.5-7.0. The temperature should be on the cooler side, around 75-78 degrees Fahrenheit.

If all goes well, you should have a nice batch of healthy Bloodfin fry in no time!
