Eye-catching fish

Fish in natural water often have a camouflage, which protects them against herons and different enemies. In a pond you should rather introduce fish with an eye-catching colour. After all you want to see your fish. Protection can be applied in many different ways.

Quickly propagating fish
A pond can accommodate just a limited number of fish, without it getting into trouble with the biological cycle. If there are too many or too large fish in a pond, the pond plants and the filter can no longer cope with the amount of waste materials and the pond will get turbid than. So, it is important to choose fish which do not grow too fast and which do not get hundreds of young ones per annum.
