Tank Mates: Who Can Swim With Zebra Danios?
Ideal Tank Mates
Tetras (Neon, Rummy Nose, Cardinal)
Corydoras Catfish
Guppies

Dwarf Gouramis
Snails and Shrimp (they usually leave them alone)
Avoid

Breeding Zebra Danios
Breeding these little swimmers is surprisingly easy, even for beginners.
The Basics
Zebra Danios are egg scatterers
Males chase females during mating
They lay hundreds of eggs at a time
Breeding Steps
Condition males and females separately with high-protein foods
Move to a breeding tank with marbles or mesh at the bottom
Let them spawn—usually happens in the early morning
Remove adults after spawning (they’ll eat the eggs!)
Eggs hatch in 2–3 days
Fry become free-swimming in 5–7 days
Feed fry with infusoria or liquid fry food initially, then baby brine shrimp as they grow.

Zebra Danios are resilient but not invincible. Poor water conditions and stress can lead to illness.
Watch for:
Ich—white spots, clamped fins
Fin Rot—Frayed or disintegrating fins
Columnaris—cotton-like patches, ulcers
Swim Bladder Issues: Floating awkwardly
Prevention
Maintain stable water conditions
Avoid overcrowding
Quarantine new fish
Offer a nutritious diet
Routine care and observation go a long way in keeping your Danios healthy and happy.

FAQs
Are Zebra Danios aggressive?
Generally, no—they’re peaceful and community-friendly. However, if they are not kept in a large enough group, they may become nippy or chase slower fish. A school with a good size helps spread out their energy and reduces bullying.
Can I mix zebra danios with bettas?
Zebra Danios are fast and curious, and bettas are slow with long, flowy fins—an irresistible target. Some people manage this combo in larger tanks with lots of hiding spaces, but it’s not a recommended pairing for beginners.
What do zebra danios eat?
They eat a variety of foods, including
Flakes
Micro-pellets
Brine shrimp (live or frozen)
Bloodworms
Blanched vegetables (like peas)
They’re not picky, but a varied diet helps them stay healthy and colorful.
How do you tell male from female zebra danios?
Males are slimmer with a slightly more intense coloration.
Females tend to be rounder, especially when carrying eggs.
During breeding, males also tend to chase females more actively.
How long do zebra danios live?
With good care, zebra danios can live up to 5 years, though their average lifespan is around 3 to 4 years. Clean water, a balanced diet, and a stress-free environment all help extend their lives.
Do zebra danios jump out of the tank?
Yes! When startled or the water parameters are off, they are strong jumpers. Always keep your tank well covered with a secure lid to prevent accidents.
