Zebra Loach Species Profile and Identification

Zebra Loach (Botia striata) is a small, peaceful, and attractively patterned freshwater fish originating from India and Bangladesh, which makes it an excellent choice for the beginner aquarist. Growing up to 3-4 inches long, with a lifespan of 5-8 years, Zebra loaches have an elongated, semi-cylindrical shape, displaying bold black and white stripes running along their body, giving them their unique and recognizable appearance.

Here are the key features for identifying a Zebra Loach:

  • Size: Grows up to 3-4 inches in length.
  • Lifespan: 5-8 years.
  • Color: Black and white stripes running along the body.
  • Shape: Elongated, semi-cylindrical body.
  • Origin: India and Bangladesh.

Zebra Loaches are benthic dwellers, meaning they primarily stay near the bottom of the tank. They are very active during the day and love to burrow in the substrate, so providing a fine, smooth gravel or sand substrate is essential for their comfort and to prevent injuries.

As a social species, Zebra Loaches are best kept in small groups of at least 5 to help prevent stress as they will feel safer in numbers. When kept in the right conditions and with the proper care, these attractive and interesting fish make a wonderful addition to a community aquarium.

Zebra Loach Supplies

To ensure your zebra loach thrives in its new home, you’ll need the following supplies:

  • A minimum 20-gallon tank: Zebra loaches are active swimmers that require ample space to explore and glide.
  • A reliable heater and thermometer: Maintain a consistent water temperature between 73-79°F (23-26°C).
  • A filter with adequate water flow: Zebra loaches appreciate a moderate water flow and a filter that can handle their bioload.
  • A high-quality aquarium light: Ensure natural day-night cycles in your aquarium to mimic your fish’s natural habitat.
