This is important due to the high amount of waste goldfish produce. If the filter does not create bubbles or stir the surface water, an aeration system (such as air stones) can also be attached to ensure that water is well oxygenated. Good filtration will ensure all water is regularly filtered mechanically and biologically via the nitrifying bacteria in the filter media. Goldfish are heavy feeders and high waste producers and require efficient filtration of a suitable size to maintain water quality and for aeration. However, there are some new modern designs that incorporate filtration and lighting which can be good alternatives. Traditional fish bowls are usually too small for goldfish and should be avoided. Certain types of goldfish may have increased space requirements, such as slimmer goldfish that are usually more active meaning aquarium size for these varieties needs to be larger and longer than generally recommended for their body size. You will also need to consider how large your fish will be when they reach adult size and the total number of fish you wish to keep. * Remember that the larger the tank and filter, the better it is for your goldfish. Minimum tank volume is about 50L and with the following tank dimensions:įilter capacity has an equally important role to play when setting up. When choosing goldfish you will also need to consider how large the goldfish will become to ensure that they are provided with adequate space as they grow. Indicators of poor health include fish that sink or bob to the surface fish that have lumps, bumps, wounds, clamped fins or a trail of excreta and fish that stay in a corner of the aquarium for a prolonged period of time. Healthy fish are also alert and swim without undue effort. Healthy fish display clear and bright body colouration and they hold their fins erect. When purchasing a goldfish first check that the seller is responsible and that their aquariums are not overcrowded. The following information will help to improve goldfish longevity, health and welfare. Housing needs to meet both their behavioural and physiological needs. Unfortunately, many goldfish do not reach their lifespan potential due to inadequate housing conditions. Goldfish have a lifespan averaging about 10-15 years, with some varieties living up to 30 years when provided with proper care. Goldfish are social and intelligent animals and are regularly seen interacting with each other and their human caregivers whom they can learn to recognise. Today, there are a wide variety of goldfish available. Goldfish originate from temperate climates and in the wild they live in cool streams, lakes, and ponds throughout Asia and parts of Eastern Europe. Fish become conditioned to regular feedings and seeing the fish as they come to the surface to feed is one of the best parts in keeping a pond.Goldfish ( Carassius auratus) are the most popular of all ornamental fish and are known for their attractive bright colours. You do not want it left to decompose, or become stuck in a nook or filter box. Keep each feeding to small amount so that your fish eat all of the food. One should offer different forms of foods (pellets, flakes, cakes, greens, insects and fruits), different enhancements (vitamin fortified, special amino acids for color enrichment, added vegetable matter) and foods that both sink and float.įish need to graze constantly, so feed them often. In their natural environment, fish have a variety of foods to choose from. During these colder times, wheat germ foods are an excellent choice for an easily digested fat source.Ĭan I feed just pellet food to my pond fish?Ĭertainly, variety is important in any animal's diet and the same goes for fish. You should decrease protein and fiber levels. As water temperature drops so does fish activity. These percentages will vary depending on season (water temperature). You want a protein level around 30%, carbs about 65% and fiber about 5%. So if you are feeding Shubunkins, Comets or Fantails, pond food or Koi food is fine to feed. In fact just about every brand of goldfish food says it is OK for Koi and pond fish (other types of carp). The nutritional requirements of both fish are very close. Digestion requires a particularly alkaline diet in protein and high in vegetable matter.Ĭan Koi and other types of pond goldfish eat the same food? Foods that normally would get digested in the stomach (as in other fish) are not good, for this reason we want to feed a food that will be absorbed by the fish as it passes through the intestine. What do I need to think about when choosing food for Koi?Īs with any goldfish species, it is important to remember they do not have stomachs, only very long intestines.
