How long do koi live?

Koi carp are among the most long lived of domestic fish when kept within an appropriate environment, and should be considered as a lifelong pet. The commonly accepted average age for a well kept domestic koi is around 50 years, however, it is not unheard of for koi to live to over 100 years – and even over 200 years in one well documented case!

How large do koi grow?

Koi carp can grow very large, given enough time and the right environment, potentially reaching over three feet in length! They are also fast growing, and will soon outgrow a pond that is too small for them, leading to potential health problems.

Do Koi Have Teeth

Below is a photograph taken on the 7th August 2004 .. and shows 10 teeth that have been shed by Koi .. these vary in size as you can see and the largest ones are probably from Koi over 28″ in length.koi_teeth2

We have set these along side a 20pence piece to give you an idea of their actual size … So when you are Vacuuming the pond if you look and ‘feel’ very carefully, then you may just find one or two of them – you will be quite amazed …

From information we have been able to gather, we understand that a Koi will shed up to 36 sets of teeth during their lifespan ..  it would seem Mother Nature got something right where teeth are concerned ..  wouldn’t it be super if she had allowed the Human species on this planet Earth, to also have 36 sets of teeth .. !!

Are koi carp expensive?

There is no one answer to how much koi carp cost, as prices vary greatly. Small, young koi carp for the pet market can be picked up for under £10 each, while mature specimens that have reached a large size and have particularly desirable colors and markings often change hands for tens of thousands of pounds – and sometimes even more! However, for the beginner koi keeper, the cost of your first koi carp should be well within your budget.

Koi Pond Beginners Guide

cache_2446408747Koi ponds come in many shapes and sizes, from the relatively modest sized pond that may hold mixed collection of koi carp and Goldfish, through to ponds of many thousands of gallons, stocked only with top quality Japanese Koi. Many Koi keepers started their interest by introducing a few Koi carp into a small, pre-formed plastic pond to provide a colourful addition to their Goldfish. How ever, whilst you may have some success in ponds like this, there is no doubt that the koi will not achieve their full potential. There are several drawbacks to Koi keeping in small ponds: the water temperature and chemical composition are prone to sudden changes which is not good for Koi, the size of the Koi is limited by the buildup of waste in the water and the shape of the Koi is likely to be affected by a limited swimming area and a lack of depth. Having accepted that there are problems with very small shallow ponds we can now take a look at the requirements for purpose built Koi ponds.

Pond Size

A Koi pond needs to provide clean, well oxygenated water in order to produce a healthy environment for fish to live and koi-pond1-150x150grow. The basic requirements are: To be large enough to accommodate the potential size that Koi can grow to ( 24 inches / 60cm plus). A pond of around 8 feet x 6 feet and 4 feet deep (2.5m x 2m x 1.2m) containing approx’ 1200 gallons (5500L) would be a sensible minimum for keeping Koi in the UK or other temperate climates. The larger the pond the better it will be. Many Koi keepers have found that what appears to be a massive pond, soon looks too small for their growing collection of fish. Many people find they end up building two, three or more Koi ponds before finally arriving at the perfect set up. While it is tempting to economise, it is well worth bearing in mind that building a good size pond in the first place is cheaper than building a succession of Koi ponds. The larger the volume of water the more stable the pond will be. A hot day can send the temperature soaring in a small pond, whilst a cold night can see it plummet. Fish are cold blooded and their body temperature matches the temperature of the pond. Sudden changes in temperature will cause physical stress and may lead to disease. This also applies to Goldfish and other pond fish. But Koi carp have been progressively interbred over many years to develop their colours and like most pedigree animals are relatively delicate. For this reason they may develop health problems in conditions where Goldfish are living quite happily. The stability of the water temperature is also greatly affected by the ratio of surface area to volume. The larger the area in relation to the depth the greater the affect of sudden changes in air temperature, if you have two ponds with the same volume but one is deeper than the other it will be less affected by temperature fluctuations. In addition to helping create a more stable environment, a good depth helps to exercise your Koi. Swimming up and down helps develop the muscles and maintain a good streamlined, cigar shape to their body. Koi that have been kept in shallow ponds typically develop a somewhat obese rugby ball shape.

Pond Construction

As well as considering the size of the pond, it is worth spending a little time considering the shape and construction method. Ponds with simple shapes and flowing curves allow a good circulation of water and avoid dead spots. Construction in concrete blocks, with a rendered surface and finished in fibre glass allow for the rounding off of corners in a rectangular Hybrid-Water-Garden--1196pond and sloping of the pond base towards the bottom drains. This method of construction is the most expensive but gives the best results. Care should be taken to make sure the type of final gel coat used with the fibre glass will completely cure and not leach styrene into the water with potentially fatal results for your Koi. There are a number of specialist fibre glass firms that will undertake this work and a firm that has experience of building Koi ponds will ensure the correct finish is used. A cheaper alternative and probably the most commonly used method of building Koi and Gold fish ponds is to use a good quality rubber pond liner. To calculate the size of liner required, measure the longest distance across the pond and add twice the maximum depth to obtain the length. Measure across the widest point and add twice the maximum depth to obtain the width. Then add a foot (30cm) to each measurement to allow for an overlap. So for a pond of 8 feet x 6 feet x 4 feet deep the liner would need to be 8 + (2 x 4) + 1 = 17 feet long and 6 + (2 x 4) + 1 = 15 feet wide. When fitting the liner, care should be taken to pleat and fold the corners carefully to minimise the chances of debris becoming trapped. The corners can be fixed down flat with special mastic tape to give a good finish.

A Koi pond should serve two main functions;
One is to provide a healthy home for your Koi.
The other is to provide “clear-water” so that you, the owner, can enjoy your Koi.

Swimming Pool Filters

One of the reasons swimming pool filter systems do not work very well on Koi ponds is that they are designed for mechanical and chemical filtration of water. Swimming pool filter systems rely on a pump that is operated for a set time each day. Pumps used for biological filters are required to run 24 hours a day. Most people who purchase swimming pool pumps for Koi ponds are “shocked” at the increase in their monthly electrical bills.

Small Commercially Available Pond filters

Let me warn you about some commercial pond filters available through nurseries, water garden supply, and internet catalog sales.
The manufacturer, like most companies, are in business because there is a demand for these product . Some product descriptions, as advertised, may seem like the solution. But seriously, who would you rather trust? The claim of a manufacturer or somebody who lives near you with a successful fish pond. I feel that your “best” source for information on proper filtration is from a person, in your area, who has successfully kept fish healthy in their own pond for several years. The best place to locate people like that is through a Koi club in your area.

How to Choose the Correct UV Light For Your Pond

There are a couple of reasons to use a UV light on your pond. One is that when installed properly, they are a 100% cure for green water. The other reason to possibly have one would be to control the water born pathogens that live in all ponds, also on all fish. To eliminate green water requires less wattage than you needed to kill certain pathogens. It is for this reason that there are different sizes of UV’s available. Depending whether your goal is simply achieving clear water, killing pathogens, or both will dictate which size UV is right for your needs. Your budget will also be a consideration in which one may be right for you. They are even made with high grade Stainless steel housing in some models! I highly recommend the use of a UV light in your pond, no matter what the size. Wouldn’t you like to have crystal clear water, low pathogen counts, and healthier fish?  A UV is the most economical way to achieving all of these goals. Regardless of what you may read, do not choose a UV light based on the size of your pond. The correct way to size a UV light is by the flow of the water going through your system in the location that the UV will be installed. I cannot stress enough that it is critical to properly size a UV light based on the flow rate at the location you will be installing it, and not the size of the pond.Your pond pump should be big enough to cycle your total pond water volume at least once every 2 hours, three at the very outside. You must ensure your UV light can cope with this volume of water. If not all is not lost. Just add a Y juntion to your main line so the UV gets half the flow and this will allow the UV time to treat the water as needed. I cannot stress enough that poor water quality is the number one cause of fish stress and illness. A UV can help towards this goal. If you maintain good water quality, the fish will usually take care of themselves. The quality of your pond water is everything to the health of your fish. Your No.1 tool in fish keeping is a water test kit.
