Bloodfin is a term that refers to a species of freshwater fish called Aphyocharax alburnus, commonly known as the bloodfin tetra. It is a popular aquarium fish that belongs to the family Characidae. This small-sized tetra is native to South America, specifically found in the Paraguay and Paraná River basins. The name "bloodfin" is derived from its distinct physical characteristics.
The bloodfin tetra is known for its unique red coloration on the lower half of its body, which appears blood-like and gives this species its common name. The upper portion of its body is translucent or silver, providing a sharp contrast to the crimson-colored lower part. With an elongated and laterally compressed body, it typically grows to around 5 centimeters in length.
In terms of behavior, bloodfins are known to be peaceful and shoaling fish, which means they prefer to swim together in groups. They do well in community aquariums, as they are compatible with various species. Bloodfins are omnivorous, primarily feeding on small insects, worms, and plant matter in the wild. In aquariums, they can be fed with a combination of flake food, live or frozen foods such as brine shrimp or bloodworms, and occasionally vegetable matter.
Due to its appealing appearance, ease of care, and sociable nature, the bloodfin tetra has gained popularity among aquarium hobbyists. Its striking red coloration and shoaling behavior make it an attractive addition to many freshwater fish tanks.
