Long-nosed Distichodus

Among the distinctive features of the Long-nosed Distichodus are its elongated head and characteristic forked caudal fin. The body coloration varies from orange to golden, with prominent vertical black stripes noticeable across the entire body. Interestingly, this striking pattern becomes less distinct with age.

This representative of African characins inhabits large rivers and their tributaries in the Congo and Zaire basins, preferring to stay in schools. Their diet primarily consists of soft vegetation, such as young shoots and leaves, but they will also readily consume worms and other benthic invertebrates when available.

Young individuals of this species are peaceful, but over time, their behavior can become quite unpredictable. They tend to show aggression towards smaller fish species and those with long fins. These fish prefer to live in schools: if kept in a group of five or more individuals, the level of aggression significantly decreases. Nevertheless, even in such a group, other aquatic inhabitants may not always feel completely safe. They coexist well with catfish and other species that prefer to stay at the bottom.

Since any large fish produces a significant amount of waste, the Long-nosed Distichodus is no exception, and maintaining water cleanliness becomes a key condition for its successful keeping. Installing an efficient filter, preferably an external canister type, and regular 30% water changes every two weeks, are usually sufficient for this task. Other necessary equipment includes an aerator, a lighting system, and a heater. The aquarium must be covered, as these fish are known for their jumping. For aquarium decoration, it is recommended to use artificial plants, arranging them in groups near shelters such as driftwood, grottoes, or imitations of castles or sunken ships. Smooth stones and coarse sand are suitable as substrate.

Although the Long-nosed Distichodus can be classified as an omnivorous species, it should be remembered that it prefers plant-based food. The lion's share of its diet should consist of plant products, such as flakes and pellets with vegetable components, fresh or frozen lettuce or spinach leaves, and peas. Meat supplements, such as bloodworms, can make up a smaller portion of the diet. It is important to provide sufficient main food, otherwise there is a risk that the fish will start nibbling on live aquarium plants.

Cases of successful breeding of the Long-nosed Distichodus in home aquarium conditions have not yet been recorded.

The long-nosed distichodus shows high endurance, and provided a balanced aquarium, health problems are generally absent. More detailed information on the symptoms of possible diseases and methods of their treatment can be found in the section “Diseases of Aquarium Fish”.

When choosing a long-nosed distichodus, preference should be given to young specimens, as they adapt more easily to aquarium conditions. Carefully inspect the fish for intact fins, absence of spots, ulcers, or plaque on the scales, which may indicate bacterial infections. A healthy specimen should show high activity and have a good appetite.

• Avoid purchasing fish with signs of emaciation or an unnaturally bloated belly.
• Make sure the fish shows curiosity and does not constantly hide in the corners of the aquarium.
• Ask the seller about the current diet to ensure a smooth transition to the foods you typically use.
