Breeding Zebra Danios
Zebra Danios are lively fish that breed easily in home tanks. Breeding them can be fun and rewarding.
To breed Zebra Danios successfully, you need the right setup and care. This guide explains how to do it step by step.
Breeding Setup
Set up a separate breeding tank to keep the eggs safe. Use a tank of about 10 gallons with clean water.
Keep the water temperature between 72°F and 78°F. Add plants or spawning mops for the fish to lay eggs on.
- Tank size: 10 gallons
- Water temperature: 72°F to 78°F
- Use live plants or spawning mops

Zebra Danios spawn in the morning. Males chase females to trigger egg laying.
The female drops eggs on plants or spawning mops. Males fertilize the eggs right away.
- Place males and females in the breeding tank
- Observe for chasing and egg laying behavior
- Remove adults after spawning to protect eggs
- Eggs hatch in about 2 days
Raising Fry
After hatching, fry feed on tiny food like infusoria or finely crushed flakes. Feed small amounts often.
Keep the water clean and warm. Change water carefully to avoid stressing the fry.
- Feed infusoria or liquid fry food first
- Move to baby brine shrimp after a week
- Maintain water temperature around 75°F
- Change 10% of water daily to keep it clean
- Use a gentle air stone for oxygen
