Choosing fish to stock in your pond varies on the size of water garden you have and the price you are willing to spend. Fish such as goldfish are easily maintained and generally won’t grow to be bigger than six inches thus making them ideal for smaller ponds. The common goldfish, comet goldfish and Shubunkin are known to be hardy. However, fancier goldfish including fantails and lionheads are more easily preyed upon.
More desirable fish such as Koi take a little more consideration, time and maintenance. Koi require at least three feet in depth, better water quality and a bigger pond as a general rule of thumb. At one year of age, Koi will generally get to about 6-8 inches, 12-16 inches in two years, with the possibility of getting up to 24-36 inches in a decade. However, the size of Koi greatly depends on how big their habitat is as well as the quality of their environment, water and maintenance. Although much goes into the care and keeping of Koi, they make great pets and can become very friendly, even eating out of your hands at dinner time. They also help in keeping your pond beautiful as they graze on algae.
Fish such as The White Cloud fish and Catfish variety aren’t typically kept as pets like Goldfish and Koi. The White Cloud Fish are often kept for the purpose of mosquito control, mostly in warmer climates while Catfish will get rather large, tear up plants and stir up sediment and most likely prey on smaller fish.
Whatever your selection, with a little care and attention, fish can add color and fun to your water garden.
