血紅皮脂魚

The Bloodfin Tetra is a small characin whose silvery body contrasts beautifully with fins tinged blood-red, a striking feature that gives the species its name. The tail, anal, and pelvic fins glow a vivid red, and a shoal of these fish adds real vibrancy to any tank. Calm and peaceful by nature, they rarely chase tankmates, making them equally at home as a centerpiece species or a supporting player in a community aquarium. Hardy and tolerant of a wide range of water conditions, they are considered an excellent choice for beginners. Given the right care, some individuals are known to live for more than a decade, making them a long-term companion for dedicated keepers.

關於血紅皮脂魚

Bloodfin Tetra: a hardy, beginner-friendly characin known for its vivid red fins. Learn about its care, temperament, and lifespan of over a decade in some cases.

迎接血紅皮脂魚前需要了解的7件事

  1. 1Shoaling brings out its beauty

    Bloodfin Tetras are natural shoaling fish, and keeping several together really shows off the deep red of their fins. They tend to feel more settled and confident swimming in a group than alone.

  2. 2Good community fish

    Their calm, non-aggressive temperament makes them easy to combine with many other species. Pairing them with tankmates of a similar size helps keep the tank peaceful.

  3. 3Tolerant of water conditions

    This is a hardy fish that copes well with a range of water conditions, part of why it is considered beginner-friendly. That said, sudden changes are still stressful, so water changes should be done gradually.

  4. 4Swims the upper-mid levels

    Bloodfin Tetras spend most of their time in the upper to middle water column, so it is worth planning tank decor with that swimming zone in mind. They are also known to jump, so a secure lid is a good idea.

  5. 5Grows to about 5.5cm

    Adults reach roughly 5.5cm in length. Even if you are starting with small juveniles, it is worth choosing a tank size that accommodates their full grown size.

  6. 6Can live over a decade

    Some individuals are known to live for more than ten years in captivity, making this a long-term commitment. It is worth planning your tank setup and routine with that lifespan in mind.

  7. 7Prepare the tank in advance

    Before adding new fish, it is important to let the tank cycle so water parameters are stable. Taking time to properly acclimate new arrivals also helps reduce stress.
