Koi Fish And Goldfish

Koi Fish or Goldfish? For people planning to have a water garden or a pond, their set-up will not be complete without fish swimming in the water. Everyone has their own criteria for choosing which ones. Their reasons for choosing one over the other could be based on practical, economic or aesthetic reasons. Once they have made their selection on which type of fish to care for, there are those who will even go a step further and name their fish, just like they would to any other pet.



Picking the type of fish may seem a simple task: just select the prettiest and most colorful ones you see. However, for those who are serious, fish selection is much more involved. There are several factors to be considered when planning the pond as to what type of fish is desired. Towards this end, the most common pond fish that people choose are Goldfish and Koi.

Both Goldfish and Koi are popular ornamental pond fish. They are hardy and can survive, although briefly, in adverse pond conditions. They even share some common historical origins and breeding development. Both are selections of carp, but they come from two different families. Goldfish are mutations from Crucian Carp (Carassius carassius) and Koi are from common carp (Cyprinus carpio).

These may be simple and non-essential differences, but for those who have no experience in having a pond and caring for fish and want to do so, it is quite an unsettling question to ask themselves, “Which should I put in my pond, Koi or

Goldfish? Or is it ok to put them both together?” The answer to this question lies in your situation and the habitat you are able to provide for either fish. If you prefer a pond or water garden that combines fish and plants, it is a good point to remember that Koi can knock and uproot the plants in the pond and even eat them. Goldfish, on the other hand, would just happily dart around the plants, but hardly disturb them. While some fancy Goldfish need to be brought inside over the winter, any Koi will survive cold climates as long as the pond is at least two feet deep.
