Lipstick Leporinus

Geographic Origin and Biotope: Major river systems of the Orinoco (Venezuela, Colombia) and Guianese rivers. Inhabits main river channels, rocky flooded zones, and areas with strong flow, grazing heavily on algae-covered rocks and submerged fruits.

Taxonomy and Morphology: An absolute giant within the Anostomidae family, reaching 35-40 cm (14-16 inches) in captivity. Built like a muscular torpedo for immense swimming power. Features the iconic 'hare-mouth' equipped with sharp, shearing incisor teeth designed to cut vegetation and crush seeds.

Social Behavior: An indefatigable, restless, and dominant swimmer. Constantly patrols the tank, investigating and biting objects. Like the Banded Leporinus, it is a notorious and vicious fin-nipper, easily shredding the fins of slower tankmates. Highly aggressive and intolerant toward its own kind in confined spaces.

Coloration and Sexual Dimorphism: Subtle but featuring a striking focal point. The body is a metallic olive/gold. Three prominent, large black blotches (or a dashed line) run along the lateral mid-section. Its namesake feature is its mouth: the lips and entire front snout are stained a brilliant, glowing FIRE RED (the 'lipstick'). Unpaired fins are also flushed with intense red/orange.

Tank Setup: Exclusively for Jumbo Tanks (MINIMUM 180-200 cm / 6-7 feet length, 200+ gallons). Will eat literally any live plant down to the roots. Scape the tank like a major riverbed: massive smooth boulders, giant driftwood, and sand. IMPORTANT: Driftwood and rocks must be heavy and secure, as a 40-cm Leporinus will violently ram and move light decor looking for food. A HEAVY, INDUSTRIAL-STRENGTH LID is mandatory to contain its massive jumping power.

Feeding: Voracious Herbivore with omnivorous tendencies. 70-80% of the diet MUST be vegetable matter to prevent fatal bloat. Feed thick slabs of zucchini, broccoli stalks, whole romaine lettuce, and jumbo pond-algae pellets daily. Supplement sparingly with large earthworms or whole shrimp. To tear food, they bite and perform violent 'death-rolls' (like a crocodile).

Water Quality: Extremely hardy. Adapts well to pH 6.0-7.5 and medium hardness. Temp 23-28°C (73-82°F). Given the massive volume of vegetable waste they excrete, industrial filtration and powerful wavemakers (for strong current) are strictly required.

Compatibility: A strictly 'Monster Fish' species. Will swallow small fish and mercilessly mutilate slow/long-finned fish. House ONLY with large, heavily armored or aggressive tankmates that can stand their ground: Oscars, Pike Cichlids (Crenicichla), massive Geophagus, Arowanas, and jumbo Plecos. Never keep 2 or 3 together: keep either ONE solitary specimen or a massive school (8+) to disperse their lethal internal aggression.

Reproduction: Impossible in home aquaria.

Risks: 1. SEVERE MUTILATION of tankmates' fins. 2. Physical destruction of tank decor, including biting through soft filter tubing/heaters. 3. Shattering lids or jumping out. 4. Fatal intestinal blockages if fed a carnivore (high-protein) diet.
