Descrição da espécie
Geographical Origin and Habitat: Originating from the Oyapock River basin, on the border between Brazil and French Guiana. Inhabits slow, wide rivers flowing through primary forests, on sandy bottoms covered with fine mud and wood.
Taxonomy and Morphology: Solox Corydoras (Corydoras solox). Large and spectacular species belonging to the "very long-snouted" Corydoras lineage. Shares the banded pattern with C. amapaensis. Easily reaches 6.5 cm (2.5 inches).
Social Behavior: Despite its size and "trunk-like" snout, it is a shy and peaceful animal. It is highly gregarious: a group of 6-8 individuals will forage together by sinking their long noses almost entirely into the sand to unearth worms.
Coloration and Sexual Dimorphism: Grayish-cream base coloration, interrupted by a conspicuous and wide black band running from the anterior end of the dorsal fin to the caudal peduncle, plus a dark blindfold over the eyes. Females are corpulent.
Cuidado, criação e companheiros de tanque
Aquarium Setup: Large tank (minimum 100 cm / 40 inches). Fine sand mandatory to protect the very delicate long snout. Set up the bottom with bogwood roots, intricate Manzanita branches, and scattered Indian almond (Catappa) leaves.
Diet and Feeding: Extraordinary benthic hunter. Uses its snout to dig deeply: it is crucial to provide live/frozen bloodworms, tubifex, and blackworms, as well as high-quality protein pellets that sink rapidly.
Water Quality: Needs excellent substrate and water hygiene. Keep the water soft and acidic (pH 5.5-7.2) and avoid drastic spikes in pollutants. An oversized filter with moderate surface current is ideal.
Compatibility and Cohabitation: Quiet and harmless. Excellent companion for fish from the Oyapock basin or similar: small Loricariids, non-aggressive Characins, and South American dwarf Cichlids. Frenetic bottom fish should be avoided.
Aquarium Breeding: Difficult to breed in captivity. Follows the temperature drop protocol. Long-snouted parents are known to be avid devourers of their own eggs if they are not promptly removed from the spawning tank.
Risks and Diseases: Extremely susceptible to damage to the rostrum: sharp gravel is a death sentence. Wounds to the long snout become infected rapidly (Flexibacter) leading to tissue degeneration.

Perfil de peixe
- Temperamento
- Semi-aggressive
- The temperament of Corydoras solox is exceptionally peaceful and highly social in nature. They must be kept in groups of at least six individuals to thrive. In proper schools, they are confident and constantly active across the bottom.
- Dieta
- Omnivore
- The diet of Corydoras solox primarily features benthic organisms and small detritus. In captivity, they eagerly eat sinking pellets and high-quality bottom-feeder wafers. Live foods like bloodworms and daphnia should be offered for optimal health.
- Expectativa de vida
- 5-10 years
- Tamanho adulto
- 6.5 cm
- Proporção sexual
- Specific M:F ratio
- A specific sex ratio is unnecessary for the general community keeping of Corydoras solox. For dedicated breeding, a ratio of two males per female is optimal. Females are visibly rounder and broader, while males are slender.
- Frequência de alimentação
- Twice daily
- It is recommended to feed Corydoras solox one or two times daily in moderate portions. Ensure the food reaches the substrate before mid-water fish consume it all. Feeding just before lights out helps them forage peacefully without stress.
- Carga biológica
- Low to Medium
- The bioload of Corydoras solox is relatively low compared to larger tank mates. Since they are schooling fish, their combined waste can accumulate over time. Consistent filtration and weekly water changes are necessary for maintaining clean water.
- Fluxo
- Stagnant
- Corydoras solox prefers a moderate water flow that replicates gentle Amazonian streams. This circulation thoroughly oxygenates the water and prevents detritus accumulation. Calm resting zones should also be provided for relaxation.
- Risco de salto
- Yes
- The jump risk for Corydoras solox is very low compared to surface-dwelling fish. However, their unique respiratory system causes occasional rapid surface darting. A secure aquarium lid is highly recommended to prevent accidental escapes.
- Reprodução
- Oviparous
- Breeding Corydoras solox in an aquarium is highly achievable with proper conditioning. Spawning is typically triggered by a large, slightly cooler water change. The female then deposits adhesive eggs on aquarium glass or broad plant leaves.
- Compatibilidade e companheiros de tanque
- Semi-aggressive
- In terms of compatibility, Corydoras solox is extremely peaceful and ideal for community setups. They coexist perfectly with small tetras, rasboras, and dwarf cichlids. Large, aggressive bottom-dwellers must be avoided to prevent undue competition.
- Nível do tanque
- Bottom
- As obligate bottom-dwellers, Corydoras solox spends the vast majority of its time on the substrate. They constantly search for food by sifting fine sand with their sensitive barbels. They occasionally dart to the surface to gulp atmospheric air.
