All About Koi Health
Koi health is of paramount importance if you want to enjoy your fish for a long time. Koi fish are known to live for decades although the average life span is 20 to 30 years. Koi are hardy and durable; but, they can get sick. Their longevity depends mainly on genetics and living conditions.
The modern koi are tough but they have lost much of the resiliency of their ancestor, the magoi carp. They can thrive in the poorest water conditions and remain unaffected by the presence of parasites. This is because of the inbreeding practice that started long ago when nishikigoi was first being developed. Breeders needed to pair koi with parents and siblings to obtain the perfect body shape, intense colors and beautiful patterns that make the present koi so admirable.
Nonetheless, the koi of today rarely get sick and if they get sick or die, you can trace the root cause to water quality problems. Similar threats to koi health are parasites, ulcer disease, predators, medicine overdose, leaping out of the water, virus infections, toxic pesticide sprays, and tumor.
Water Quality
Poor water quality is the leading cause of koi death. You will need to watch out for the pH, ammonia, nitrite, nitrate and oxygen levels in your pond. Even marginal changes in their levels can adversely affect koi health. PH refers to the acid and alkaline levels of your water. Koi need a pH of 7.0 through 9.0. Ammonia is formed by your koi in the form of waste. It can be removed effectively by using biological filter system that takes advantage of the nitrification cycle.
Bacteria will convert ammonia into nitrites. However, nitrites are still toxic to the koi and must also be changed by other bacteria into nitrates that are relatively harmless to the koi. Nitrates, in turn, are absorbed by the plants as well as algae in the pond. You already know how oxygen is needed to sustain life. As your koi grow in size, they will need more dissolved oxygen. To Make sure that there is plenty of oxygen in the pond water set up a waterfall, jets or air pump, or place air stones to add more oxygen into the water.
Parasites, Ulcer Disease and Bacterial Infections
If the koi fish die or display abnormal behavior despite the good quality of your water, you could suspect the reason to be either parasites or bacterial infections. Parasites like anchor worms or fish lice can be destructive to your fish. The initial signs are red or white pimples that quickly turn into sores. The ulcer can reach into the muscles of the fish so you need to catch the disease while still in its early stages.
You will need to keep you koi free from parasites. Keep the affected fish in salted water and feed with medicated food. You can swab the sores with betadine to help them heal. Consult with a veterinarian on how best to treat your koi.
Quarantine
You will have to quarantine any brand new fish for three weeks before introducing them to the pond. During this period, you will need to treat the fish for parasites. If you do not have a separate quarantine tank, make sure to purchase your koi only from trustworthy dealers that guarantee their fish to be parasite-free. Also carefully pick the plants for addition to the pond which also needs to be parasite-free.
Overcrowding
If you continue having koi health problems (like stunted growth or erratic behavior) even if your water is of top quality and you purchased only parasite-free fish, you may want to evaluate your koi population. Your fish may be suffering from stress because of overcrowding.
