Some pond owners allow aquatic snails from specialist shops to cost quite a bit of money, while the molluscs settle down under appropriate conditions, so to speak "by themselves". In some cases, they are also registered on aquatic plants or other animals. As some species feed on algae, for example, they can work well in the pond and improve water quality.
fishThere were no fish in the pond used but still swim through the water suddenly? This is rare but possible. For example, when aquatic plants are taken from a pond with fish and spawning was on them. However, the spawn can also be recorded on other animals, because juvenile fish can still hatch even if the spawn was humid for several hours outside the water.
Of course, the fish can also be used and for many, they necessarily belong to a garden pond. Those who decide for these pond inhabitants, but should pay attention to a few points:
Size of the pond
When setting up the pond, it should be clear whether fish should be kept in it later and in which way the choice falls. For it depends on which volume of water is needed and how deep the garden pond must be for safe wintering.
Easy care goldfish or demanding koi? From the claims of the fish depends on the effort that must be operated in the attitude.
With the exception of kois, most species of fish can easily be overwintered in the garden pond as long as it is deep and large enough to prevent complete freezing.
Goldfish are peaceful and therefore can be associated with other peaceful species such as gold-throated and grass carp. But that does not apply to all species and breeding forms. When buying fish should therefore be a detailed consultation in the specialized trade.
ShellfishPond mussels are difficult to observe and often fall on the pond cleaning. Their larvae can be entered into the garden pond via fish and less often via plants. The larvae attach themselves to fish and live first as parasites. When these larvae, the so-called glochidia, develop into adult mussels, they feed on microorganisms and algae, which they filter out of the water. So they too can contribute to a good water quality.
birdsFor many birds, garden ponds are attractive points, serving as a source of water and food. They catch insects and drink from shallow areas. Larger ponds occasionally attract ducks, which often go for a swim. But visiting birds at the garden pond is not always so peaceful and beneficial. Especially when fish have been used, a visit to the gray or heron rarely takes a long time. For young birds, the garden pond can also be life-threatening. The animals in the pond should therefore be protected as well as some animals in front of the pond.
Tip: A heron dummy can keep the danger away from the fish because it symbolizes flying animals that the garden pond is already "occupied".
Attract and protect sentient beingsMany micro-organisms and animals settle on their own in and around the pond and do not require any special conditions for that - water and some plants are already sufficient for them. But those who create ideal conditions for a variety of animal species and want to protect them, should pay attention to several factors:
Water depth vary
The pond is best laid out in steps, so that there are different heels along the sides. This offers different animal species the appropriate depth of water.
Install exit possibilities
Very shallow bank areas and stable stacked stones or slabs are beneficial for many species. Birds and other wildlife can drink here more easily. In the pond sunken animals can save themselves in these places. Flat shore areas with a corresponding perimeter can also serve as a bird bath.
Dense marsh plants, water lilies with large floating leaves and aquatic plants provide shelter through hiding places, food for many creatures and in the case of aquatic plants also oxygen. They serve as a storage place for spawning, can provide shade and also consume nutrients, which in turn benefits the water quality. Pond edge, shallow shore areas and the pond itself should therefore be varied planted. The amount of plants should not be excessive and designed for growth.
Offer hiding places
Densely grown and large-leaved plants are already hiding places in the water and on the shore, but it should not be left.Also stones piled up to caves, heaps of twigs and foliage, perennials, hedges and nesting boxes are gladly accepted. They provide protection, attract various animals and can even be used decorative to design.
Sun and shade
All day bright sun or only shade do no pond well. It is better if at least part of the water surface is slightly shaded. This prevents the water from overheating in the summer. In addition, the change from shady to sunny areas attracts more animals.
