Scientific Name:  Devario aequipinnatus

Common Name: Giant Danio, Golden Giant Danio

Adult Size: 4 - 6 inches

Life Expectancy: 5+ years

Habitat: India, Nepal, Bangladesh, Myanmar, Thailand

Minimum Tank Size: 55 gallons

Ideal Tank Conditions: 

  • Temperature Range: 68 - 80° F
  • pH Range: 6.5 - 7.5
  • Water Hardness: 6 - 10

    Temperament: Peaceful

    Diet & Nutrition: Omnivorous and will accept a wide range of foods, including flake, freeze-dried, frozen, and live foods. To bring out the best coloration, offer live foods, such as bloodworms, brine shrimp, daphnia, or mosquito larvae. If live foods are not available, substitute the frozen counterpart. Occasionally include vegetable flakes in their feedings to provide a well-balanced diet.

    Breeding & Spawning: Relatively easy to breed, and the fry are fairly easy to raise. Spawning should be attempted in a roomy tank that has some exposure to the sun if possible, as natural sunlight triggers spawning. Keep the water warm, in the range of 77 to 82 degrees Fahrenheit, with a pH of 7.0 or below. Provide fine-leafed plants, such as java moss, or a spawning mop. Condition the breeder pair with live foods such as brine shrimp.

    During spawning, up to 20 eggs are produced during each pairing, which continues until as many as 300 are scattered on the plants or spawning mop. Remove the breeding pair once the eggs are laid, as the parents will consume the eggs and fry. Eggs hatch in 24 to 36 hours and the fry become free-swimming approximately 48 hours later. Feed the fry commercially prepared fine fry food and freshly hatched brine shrimp.

    Gender: Females are attractively colored but generally are less vivid than the males. The body is iridescent gold with steel-blue-colored spots and stripes running lengthwise from the gills to the tail. In females, the stripes bend upward at the base of the tail, while in males the stripe runs straight, extending through the tail. The abdomen of the female is fuller and rounder than that of the male. Males are also noticeably slimmer than their female counterparts.
