Sterbai Corydoras

A spotted, warm-water cory that tolerates the high temperatures discus and rams demand — the bottom-dweller of choice for heated tanks. Same golden rule: sand substrate and a proper group.

• Minimum footprint: 20 gallons; a 25+ gallon tank gives real swimming room.
• Preferred swimming zone: bottom of the water column.
• Social — keep a group of at least 6.
• Care level: easy.

• Temperature: 74–84°F
• pH: 6–7.5
• Hardness: 2–15 dGH (Moderate)

Stable parameters matter more than perfect ones — aim for consistency before chasing an exact number.

An omnivore — offer a staple flake or pellet plus regular frozen or live foods (daphnia, bloodworm, brine shrimp) and some vegetable matter for balance.

A further 1 species pair with Sterbai Corydoras as conditional — workable with the right tank and precautions.

Standard tanks at or above the recommended 25 gallons:

• 29 gallon 30 × 12 × 18″
• 30 gallon 36 × 12 × 16″
• 40 gallon Breeder 36 × 18 × 16″
• All tank sizes

• Start from a 20 gallon minimum and plan the full group size (6+) before you buy.
• Activity level is moderate, which affects how much of the tank it uses and how much it adds to the bioload.
• Zoning matters: this species lives mostly in the bottom zone, so choose tank mates that occupy other levels.

Compatibility depends on tank size, water chemistry, temperament, and adult size. Run a full check against any species in our database.
