Gold Danio
Danio albolineatus
Animalia›Chordata›Actinopterygii
Variety of Pearl Danio · gold
📍 Southeast Asia
A color variety of the pearl danio (Danio albolineatus) selectively bred to express a warm golden-yellow body in place of the typical pearlescent sheen. It retains the same active, peaceful schooling behavior and hardiness as the standard pearl danio and is well-suited to community tanks.
Care Guide
Diet
Gold Danios are omnivorous and should be fed high-quality flake foods or small pellets as a staple, supplemented 2-3 times weekly with frozen foods like brine shrimp, daphnia, or bloodworms. Feed small amounts once daily, only what they can consume in 2-3 minutes, as they are active foragers.
Behavior
Gold Danios are highly active, fast-swimming fish that spend most of their time in the upper water column darting around in schools. They are peaceful and social, requiring a minimum group of 6 to exhibit natural schooling behavior and reduce stress. They are hardy and adaptable, making them excellent for community tanks.
Breeding
Breeding Gold Danios in captivity is possible but requires specific conditions including slightly warmer water (around 26-27°C), dense vegetation or spawning mops, and separate breeding tanks. They are egg-scatterers that produce hundreds of eggs; parents will eat eggs and fry, so removal of adults after spawning is necessary. Fry are tiny and require infusoria or liquid fry food initially.
Tank Mates
Similar size, peaceful temperament, and water parameter requirements make them ideal community companions
Closely related species with identical care needs and compatible schooling behavior
Peaceful bottom-dweller that won't compete for food or space in the upper water column
Small, peaceful fish with similar water requirements; keep in separate schools to avoid confusion
Peaceful invertebrate that helps with algae control and won't be harassed by active danios
Common Diseases
Ich (Ichthyophthirius multifiliis)
White spots on body and fins, rapid breathing, flashing against objects, lethargy
Raise water temperature gradually to 28-29°C, perform daily 25% water changes, use aquarium salt (1 teaspoon per 5 gallons) or commercial ich treatment for 7-10 days
Fin Rot
Frayed or disintegrating fins, white or gray edges on fins, lethargy
Improve water quality with frequent water changes, reduce stocking density, treat with antibacterial medication or salt baths; remove sharp decorations
Columnaris (Flexibacter columnaris)
Whitish film on body or mouth, loss of appetite, rapid breathing, fin deterioration
Perform large water changes immediately, treat with antibacterial medication, increase aeration, maintain optimal water parameters and temperature
Velvet Disease (Oodinium)
Fine golden or rust-colored dust on body, rapid breathing, scratching behavior, clamped fins
Darken the tank, raise temperature to 28-30°C, use copper-free velvet treatment, perform daily water changes for 7-10 days
