How to breed goldfish
Goldfish feel particularly comfortable in ponds that have several levels. In addition, at least one third of the pond surface should be shaded. Aquatic plants for different depths also create “feel-good zones” for the goldfish. They also provide food, shelter and shade.
How does a goldfish have babies?
In addition, the male fish swim against the females to encourage them to lay eggs. When the time comes, the females lay 500 to 3000 eggs, which are immediately fertilized by the male. After only five to seven days, the almost transparent larvae hatch and attach themselves to aquatic plants.
How and when do goldfish breed?
Goldfish reproduction occurs between spring and summer. It is called spawning. During the entire spawning season of a year, around April to May, the female goldfish can spawn up to ten times.
Can goldfish reproduce in the pond?
Goldfish can multiply quickly in the garden pond. When the juvenile fish become too many, they can be offered on the Aquaterra association’s stock exchange. As soon as the ice has melted, there will be offspring again in the garden ponds.
How do I know if my goldfish is pregnant?
When your male goldfish are ready to breed, they will develop small white bumps called “spawn bumps” on their heads, gill covers, and pectoral fins. If you spot these white dots on your male fish, there’s a good chance your female fish is pregnant.
What do young goldfish eat?
- Lamb’s lettuce,
- lion count,
- broccoli and kohlrabi greens,
- Peas, boiled until soft and pureed (if possible without the hard-to-digest shells),
- potatoes, salt-free boiled,
- Rolled oats, scalded with boiling water.
How many baby goldfish survive?
The female can spawn up to ten times during the breeding season, but all of the offspring will never survive.
Can goldfish starve in the pond?
As a rule, fish keepers think that their animals have starved to death over the winter. However, pond fish usually stay close to the bottom and do not need food. “In fact, the goldfish didn’t starve, they suffocated,” says Ingeborg Polaschek.
Can fish live in a pond without a pump?
It is possible to keep fish in a pond without a UV filter or pond pump. Fish are animals that eat and therefore produce excrement. That’s why it’s important not to put too many fish in your pond.
How often do you have to feed goldfish in the pond?
Twice a day is completely sufficient. It is important that the fish eat the food completely within a few minutes. Otherwise, superfluous residues will sink to the bottom and contaminate the water.
What does a goldfish need in the pond?
The optimal fish stock is two goldfish per cubic meter of water. Planting in the pond, the right amount of food, clean and preferably filtered water and a good supply of oxygen are important for the well-being of the fish. In addition, ponds should be cleaned regularly.
Why do the goldfish die in the pond?
There must be enough oxygen in the pond so that the fish can breathe out the carbon dioxide they have absorbed. If there is too much carbon dioxide in the water, the fish can no longer absorb enough oxygen through their gills and suffocate.
How do I recognize lack of oxygen in the pond?
A lack of oxygen is best recognized in the early morning hours (around 6 a.m.) by observing the behavior of the fish. If the fish gasp for air on the water surface or cavort around the outlet of the filter, this is a clear sign of insufficient oxygen in the pond water.
How old does a goldfish get in a garden pond?
Goldfish can live 20 to 30 years! Interestingly, the color of goldfish only develops over time. They only turn golden when they are 8 months old, before that they still show the gray of the gable.
How do I get more oxygen in the pond?
As technical means of increasing the oxygen content use filters, pond aeration and an oxygen pump. Active oxygen supplies the pond with oxygen within a short period of time. The water can also be enriched with oxygen through water features, streams or waterfalls.
How fast does a baby goldfish grow?
They often grow to over 30cm and multiply endlessly from the second year onwards.
Why do goldfish eat their young?
When they are hungry they eat their young, which has the advantage that there is no overpopulation. But some will always survive if there aren’t too many in the pond yet. This is how they maintain the balance in the pond.
When do goldfish have babies in the pond?
Goldfish begin courtship in late spring, once temperatures exceed 15 degrees. The abdomen of the female becomes thicker due to the eggs located in it. If the female gives in to the male’s wooing, she remains over an aquatic plant.
When do goldfish turn red?
The goldfish? Once the tiny ones have finally grown to about 10 to 12 cm, they start to change colour. The deep green, almost black fish slowly, within three or four weeks, become red fish, but also white or red-white fish.
What to do if there are too many goldfish in the pond?
A planted pond and fish consume oxygen. If there are many fish in the pond, oxygen must be supplied in any case. A stream, waterfall, water feature or fountain is often sufficient for this. A pond aerator also prevents a lack of oxygen in the pond.
