Celestial Pearl Danio

A gem-like nano danio speckled with pearl dots. Perfect for a small planted species tank, but too tiny to live with anything that has a big mouth.

• Minimum footprint: 5 gallons; a 10+ gallon tank gives real swimming room.
• Preferred swimming zone: middle of the water column.
• Social — keep a group of at least 6.
• Care level: easy.

• Temperature: 68–78°F
• pH: 6.5–7.5
• Hardness: 3–12 dGH (Moderate)

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

Standard tanks at or above the recommended 10 gallons:

• 10 gallon 20 × 10 × 12″
• 15 gallon 24 × 12 × 12″
• 20 gallon High 24 × 12 × 16″
• All tank sizes

• Start from a 5 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 middle 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.
