Corydoras sodalis (False Network Cory) Large - Aquarium Glaser

Corydoras sodalis is a peaceful, medium‑small Corydoras species prized for its elegant net‑like (reticulated) black pattern over a silvery body. It’s commonly called the False Network Cory, because it resembles Corydoras reticulatus but lacks that species’ bold dorsal fin blotch. 

Identification

• Body pattern: Fine black “network” or swirling reticulated pattern
• Body color: Pale silver to light olive
• Dorsal fin: No large black patch (key ID trait vs reticulatus)
• Caudal fin: Dark banding or striping

This subtler patterning is why it’s referred to as false network rather than true network Cory. 

Scientific & Trade Names

• Scientific name: Corydoras sodalis
• Common names: False Network Cory, Network Cory
• Sometimes sold as: Brochis sodalis (older or alternative classification used by exporters) 

Natural Range

• Countries: Brazil, Peru, Colombia
• Habitat: Shallow Amazon tributaries, floodplains, and slow‑moving creeks
• Substrate: Sand, fine silt, leaf litter

They naturally live in large shoals in calm, often tea‑stained waters rich in organic debris. 

Size & Longevity

• Adult size: ~4–5 cm (1.6–2.0 in)
• Lifespan: 8–12 years with good care

They stay smaller than most laser or bronze Cory species, making them ideal for mid‑sized community tanks. 

Ideal Water Parameters

Clean, oxygenated water is more important than exact numbers. 

Tank Setup

• Minimum tank: 15–20 gal (long footprint preferred)
• Group size: 6+ (social shoaling species)
• Substrate: Fine sand or very smooth gravel (barbel safety)
• Décor: Driftwood, leaf litter, smooth stones
• Lighting: Low to moderate

They appreciate shaded areas and will display more natural behavior in darker, naturalistic layouts. 

Diet

Omnivorous bottom‑feeder

• Sinking pellets or wafers
• Frozen/live foods: bloodworms, daphnia, brine shrimp
• Feed after lights dim to ensure they get food in community tanks

They are often mislabeled as “clean‑up fish” but require targeted feeding to thrive. 

Temperament & Compatibility

• Temperament: Very peaceful
• Best tankmates:
  Tetras, rasboras, dwarf gourami, peaceful dwarf cichlids, other Corydoras
• Avoid: Aggressive fish, sharp substrates

They coexist well with other Cory species but socialize best in same‑species groups. 

Breeding Notes

• Successfully bred in aquariums
• Spawning usually triggered by:
  • Cooler water changes
  • Increased dissolved oxygen
• Classic Corydoras T‑position spawning
• Eggs laid on glass, plants, or décor
