About
The bronze cory is one of the most widely kept Corydoras, with tank-bred lines available in green and albino forms. Wild fish occur across much of northern South America. They sift sand for insect larvae and organic debris; smooth substrate is essential to protect barbels. Keep in groups of at least six—social stress appears when kept in pairs or trios. Hardy and adaptable within tropical parameters; occasional surface gulping is normal (intestinal air breathing). Egg scatterers that glue eggs to glass, plants, or broad leaves.
Feeding & Diet
Sinking wafers or pellets; frozen bloodworm, tubifex, or brine shrimp; occasional vegetable-based tabs.
Frequency: 1–2× daily
Feed after lights-out or target feed so mid-water fish do not steal all food.
Habitat
Native Region: South America (widespread—Trinidad to Argentina in suitable habitats)
Slow streams, pools, and flooded zones with soft substrate and vegetation.
Sand or very smooth fine gravel; gentle flow; driftwood and plants; footprint matters more than height.
Behavior
Activity Level: Moderate
Schooling Size: 6+ recommended
Constant bottom activity; rests in groups; do not combine with sharp substrate or aggressive bottom fish.
Breeding
Difficulty: Moderate
Type: Egg scatterer
Sexual Dimorphism: Females broader and deeper-bodied when mature; males often slightly smaller.
Cool water change can trigger spawning; eggs on glass and plants; adults may eat eggs—separate if raising fry.
Tank Setup
Substrate: Sand
Plant Safe: Yes
Open sand runways for foraging; caves optional.
