Keep your aquarium water clean is the first rule in caring for your Koi. This is not simply removing rubbish or water pollutants using a brush or filter. This also means regulating the temperature, transparency, dissolved oxygen and the amount of nutrient concentration. The water pH should be kept between 6 to 9 to allow your Koi to flourish. Monitoring of water quality should be done regularly to ensure cleanliness and safety of the animal. Change about 1/3 of the total water volume every two or three weeks, and the filtration system should be cleaned once a month.

Feed them two to three times regularly. Make sure the fish food you are feeding to the Koi is suitable and is specially prepared for them. These can be in the form of stick or pellet. Moreover, each fish stage does not require the same protein content in their foods. Juveniles need higher protein compared with adults. Also, feed them with food that can be consumed within a few minutes because uneaten foods might lead to poor water quality, causing cloudiness, phytoplankton bloom and fish disease.

Determine the size of your aquarium before stocking Koi. Having too many Koi in a very small aquarium can affect the quality of your water because ammonia and nitrate levels increase. Make an aquarium measurement before stocking to ensure that you provide a suitable environment for your Koi. The recommended ratio for the Koi and other ornamental fish is 1 inch in fish size per gallon of water.

Examine your Koi regularly. The fish becomes sluggish and weak if there are irregularities in the water chemistry and nutrition. They might get sick--or worse, die--if bacterial infections are not treated immediately. Diseases can arise from the introduction of other infected fish or damaged plants. It is strongly advised to isolate any sick Koi from the rest and change the water at once to prevent the disease outbreak.
