Preparing For Hatching
As the days go by, the embryo grows more defined. The eyes become visible, and the tail starts to wiggle. These are signs the goldfish is getting ready to hatch.
The embryonic sac provides all the nutrients the embryo needs. Soon, the goldfish will break free from the egg. This stage usually takes about 4 to 7 days, depending on water temperature.
| Stage | Description |
|---|---|
| Day 1-2 | Rapid cell division, formation of layers |
| Day 3-4 | Heartbeat visible, shaping of body parts |
| Day 5-7 | Eyes visible, tail movement, hatching preparation |
Make sure the water temperature is between 70-75°F (21-24°C). This ensures the eggs develop properly.
- Monitor the water quality.
- Avoid sudden changes in temperature.
- Keep the environment clean.
Following these steps can help the goldfish eggs develop into healthy fry.
Caring For Goldfish Eggs
