Sarare Corydoras

Geographic Origin and Biotope: Exclusive member of the Rio Sararé basin (central Brazil). Its colonies populate pristine gallery forest streams ("creeks"), where crystalline, weakly flowing, and oxygen-loaded waters flow over a soft sandy bed studded with roots and rounded stones.

Taxonomy and Morphology: Moderate size, settling around 5.5 cm (2.2 inches). Classified in the "long-snouted" morphotype, it boasts a long snout, cephalically flattened, and a more sinuous and slender profile that helps it sink in search of tubificids in the compact substrate.

Social Behavior: Very resourceful species provided it enjoys adequate company. Requires the constant presence of thick schools (minimum 6-8 fish). A large school neutralizes the fish's shyness, allowing bold choral inspections in broad daylight.

Coloration and Sexual Dimorphism: Light dotted livery of great value. A silvery-cream base is covered by minute black spots scattered everywhere (including snout), while a strong and marked black spot stands out on the dorsal fin ("dorsal blotch"). Mature females have a prominent abdominal diameter.

Aquarium Setup: Fine silica sand is not an option for the survival of the long snout. Obligatory rounded furnishings (river stones), intricate woody branches like Red moor, and generous shading to avoid excess glare lethal for tranquility.

Diet and Feeding: Tireless foraging hero. Demands a protein and varied menu. Feed with excellent bottom feeder tablets, interspersed with abundant bi-weekly rations of live baits (large bloodworms, white worms, or brine shrimp) dropped in the dark to defeat food predators.

Water Quality: Being an Amazonian animal imposes exceptional care: zero tolerance to pollutants (Nitrites, Ammonia). Weak GH (2-12). The optimal pH must be slightly acidic-neutral (6.0 - 7.2) together with fixed temperatures of 22-26°C (72-79°F). Nocturnal oxygen drop causes asphyxia and death.

Compatibility and Tankmates: Inhabitant of high-class Amazonian communities. In total harmony with Nannostomus, schools of Bleeding Heart Tetras, Hyphessobrycon, and docile Apistogramma. Turbulent, voracious cichlids or large diggers are incompatible, as they would induce lethargic terror and starvation in the Corydoras.

Aquarium Reproduction: Occurs according to the T-mating ritual induced by means of intense artificial "monsoons" (large cool RO changes). They lay conspicuous and wide adhesive eggs affixed randomly in the tank. Lightning-fast isolation of the eggs to overcome the massive parental cannibalistic instinct.

Risks and Diseases: Sharp substrates will unfailingly cause deadly bacterial or mycotic necrosis to the extremely fragile sensory barbels of the snout. Never use for prophylaxis shock medications containing high concentrates of Copper or Malachite green.
