Long-nosed Distichodus

Geographic Origin and Biotope: Vastly spread throughout the immense Congo River basin and its major tributaries. Prefers the margins of deep, moderate-flowing channels, browsing among rocky crevices and drowned forest roots.

Taxonomy and Morphology: A giant within the Distichodontidae family. While slightly smaller than sexfasciatus, it still grows to a staggering 40-45 cm (16-18 inches). The key morphological distinction is the head: it features an elongated, pointed, 'anteater-like' snout (rostrum) ending in the same powerful, fleshy lips equipped with sharp, shearing teeth. The body is highly compressed laterally but very deep-chested, built for bursts of speed.

Social Behavior: Suffers from the exact same 'Dr. Jekyll and Mr. Hyde' syndrome as its cousin. Very young specimens (2-4 inches) are shy, peaceful, and stunningly colored. As they grow massive, they become grumpy, highly territorial, and prone to violently biting slow-moving tankmates. They become extremely intolerant of their own kind and will engage in devastating brawls for dominance in all but the most massive public aquaria.

Coloration and Sexual Dimorphism: Juveniles are show-stoppers: golden-yellow, bright orange, or rusty-red base color slashed vertically by 6 to 8 perfectly solid black tiger stripes. Sadly, as they grow past 20 cm, the brilliant reds fade entirely. A massive adult is usually a washed-out muddy yellow, grey, or olive, with the black stripes fading into smudged shadows. Externally identical sexes.

Tank Setup: Needs a minimum tank length of 180-200 cm (6 feet) and plenty of turning width. LIVE PLANTS ARE STRICTLY BANNED: it will aggressively bite through the stems of any plant, turning it into mulch in hours. Provide a soft sand or smooth gravel substrate. Scape entirely with massive, heavy, round boulders and huge driftwood. Be careful not to create narrow caves where its long body or snout can get wedged as it grows. Strong filtration and flow are highly recommended.

Feeding: Voracious Herbivore/Omnivore. 60% of its diet MUST be vegetable-based to prevent fatal digestive bloat. Offer thick slices of raw zucchini, whole shelled peas, romaine lettuce, and massivore spirulina tablets. The remaining diet can be chunky, meaty foods like whole shrimp, mussels, and earthworms. Because they chew and spit fibrous veggies, they create a colossal mess that clogs filters rapidly.

Water Quality: Generally hardy, but prefers the softer, slightly acidic waters native to the Congo Basin. pH 6.0-7.0. Temp 23-26°C (73-79°F). The sheer volume of waste they produce demands industrial-grade biological and mechanical filtration (large sumps).

Compatibility: Treat it like a massive, aggressive Cichlid. NEVER house with slow-swimming or long-finned fish (Angelfish, Discus) or it will mercilessly bite off their fins. NEVER house with its own kind. Keep STRICTLY AS A SOLITARY SPECIMEN in Monster Fish communities. Best tankmates are robust, aggressive giants: huge Bichirs (Polypterus), giant Synodontis, or massive Central American Cichlids (Jack Dempseys, Green Terrors).

Reproduction: Unrecorded in private home aquaria.

Risks: 1. INSTANT DESTRUCTION of all aquatic plants. 2. Visual disappointment (the bright juvenile colors vanish entirely in adulthood). 3. Biting/Mutilating peaceful tankmates. 4. Intraspecific murder if two are kept together.
