Introduction: Welcome to the world of the Lined Barb, a striking freshwater fish known for its beautiful horizontal stripes and lively behavior. Scientifically named Desmopuntius johorensis, this species is admired for its sleek appearance and schooling nature, making it a popular choice among aquarists. Native to the clear streams and rivers of Southeast Asia, the Lined Barb adds both movement and elegance to any community aquarium.
Scientific Name: The Lined Barb is scientifically known as Desmopuntius johorensis. It belongs to the family Cyprinidae, which includes various species of barbs and other similar fish.
Water Quality and Temperature: To create an ideal environment for the Lined Barb, maintain the following water parameters:
- Temperature: Keep the water temperature between 72°F to 79°F (22°C to 26°C) for optimal health.
- pH Level: Maintain a pH level between 6.0 and 7.5 to mimic their natural freshwater habitat.
- GH Level: Aim for a general hardness (GH) level between 5 to 12 dGH, which suits their needs.
- KH Level: Maintain the carbonate hardness (KH) within the range of 2 to 8 dKH for stability.
Feeding: The Lined Barb is an omnivorous species with a hearty appetite. Provide a balanced diet that includes:
- Flake Foods: High-quality flake foods formulated for tropical fish.
- Pellets: Nutrient-rich pellets designed for small to medium-sized fish.
- Live or Frozen Foods: Offer brine shrimp, bloodworms, or daphnia for variety and protein.
- Vegetables: Supplement with blanched vegetables like zucchini or spinach to provide essential vitamins and fiber.
Tank Mates: The Lined Barb is a peaceful schooling fish that thrives in groups. They are best kept with other similarly sized, non-aggressive species such as tetras, rasboras, and small catfish like Corydoras. Avoid pairing them with overly aggressive or very small fish that may become stressed or nipped. A group of at least six Lined Barbs is recommended to encourage natural schooling behavior and reduce stress.
Substrates and Tank Decorations: For the Lined Barb, a soft substrate such as sand or fine gravel is ideal, allowing them to forage comfortably. The tank should be well-planted with plenty of open swimming space, as these active fish enjoy darting around the aquarium. Include rocks, driftwood, and other decorations to create hiding spots and mimic their natural riverine environment. A moderate water flow will also be appreciated, as it simulates their natural habitat.
Suitable Plants: Lined Barbs appreciate a well-planted tank that provides both cover and grazing opportunities. Hardy plants such as Java Fern, Anubias, and Amazon Sword are excellent choices, as they can withstand the activity of the barbs. Floating plants like Water Lettuce can also be added to diffuse light and create shaded areas, enhancing the fish’s comfort.
Sexing: Sexing Lined Barbs can be challenging, as males and females are similar in appearance. However, during the breeding season, females may appear slightly rounder and fuller-bodied due to the presence of eggs. Males might display more vibrant coloration and may become more active in courting behavior.
Breeding: Breeding Lined Barbs in captivity can be accomplished with the right conditions. Set up a separate breeding tank with slightly warmer water and fine-leaved plants or spawning mops for the female to deposit her eggs. The male will fertilize the eggs, which will hatch in about 24 to 36 hours. The fry should be fed on infusoria or finely crushed flakes until they are large enough to consume more substantial foods. Remove the adult fish after spawning to prevent them from eating the eggs.
Maximum Size and Longevity: The Lined Barb typically grows to about 3 to 4 inches (7.5 to 10 cm) in length. With proper care, they can live up to 5 years or more, providing a long-term addition to your aquarium.
General Information: The Lined Barb is a visually striking and active species that brings life to any aquarium. Their peaceful nature and compatibility with a wide range of tank mates make them an excellent choice for both beginner and experienced aquarists. Their schooling behavior and distinctive appearance make them a focal point in community tanks.
A Fun Fact: The Lined Barb is known for its ability to adapt to various water conditions, making it a versatile species in the aquarium hobby. Their sleek, streamlined body and distinctive horizontal stripes make them easy to identify and a pleasure to watch as they move gracefully through the water.
