Do Koi Carp Need Sunlight? 1 355

All animals, including koi carp, need light to live! While artificial lighting can help you to see the depths of your pond more clearly or allow you to view your koi once the sun has gone down, natural lighting in the form of sunlight is vital to koi, for a wide variety of reasons.

Day and night cycles

All animals live out their lives affected by their “circadian rhythms”, which are caused by the natural cycle of darkness and light. It is therefore important to make sure that your pond is positioned in such a way that your koi pond will be exposed to natural light and feel the effects of the daily and seasonal lighting changes. This is important in order to keep your koi healthy and their metabolisms ticking over normally.

Vitamin D

Vitamin D is an important vitamin that cannot be artificially created and is only generated through sunlight. Vitamin D enables plant and animal life to grow and thrive. It is responsible for a wide range of processes including building and maintaining a healthy immune system and contributing to the growth of strong teeth and bones.

Do koi carp need sunlight?While humans get their daily vitamin D dose directly from the sun, koi carp cannot process it in this way. To get their supply of vitamin D, koi need to eat plants and animals that have already absorbed it.

Plant growth

Sunlight is also vital in order to grow strong, healthy plants in your koi pond and to allow the process of photosynthesis and oxygenation of the water.

Exposure to sunlight also means that the plants in your koi pond will be rich in vitamin D, which as already mentioned, is essential for healthy koi.

The colors of koi in natural light

Natural lighting in the form of sunlight also helps your koi’s colors to really shine through. As well as showing the koi off in their best light, sunlight will contribute to the development of healthy color pigmentation.

Too much sun

While sunlight is vital for your koi pond in order to ensure that your fish and plants thrive, it is also important to ensure that there is a shaded area of the pond. This allows the koi to get out of the hot sun when they need to cool down.

Finally, too much bright light over the pond for long periods of time can contribute to bacteria growth and algae blooms, so it’s important to get the balance of light and shade just right!

Keeping exotic fish as pets 0 374

Exotic fish

There’s something mesmerising about watching a tank full of brightly coloured fish swim around. Do they make good pets though? Is it hard to keep exotic fish? With the right pet care and pet advice, exotic fish make great, if unusual pets.

Tank size

Go for the biggest sized tank you can afford and have room for. The bigger your tank, the easier you’ll find keeping the balance of the water right. Your fish need plenty of room to swim too. Aim for at least a 20-gallon tank.

Tank set-up

You’re going to need a heater to warm the water. You’ll also need a filter to ensure clean, healthy water, which is crucial for fish to thrive. It’s advisable to add an air pump to boost the oxygen levels.

You’ll also need a light for the tank, and a timer for the light, so it’s not on all the time. Bear in mind a fish tank should be placed out of direct sunlight, away from draughts and heating sources.

On top of the things that make your tank work you’re going to need everything that goes into your tank; gravel for the bottom, plants, and decorative caves and tunnels so your fish can hide if they want to.

You can usually buy aquarium starter kits at pet food stores if you want help in pulling everything together.

Getting the water right

The filter will cycle your water to make it suitable for fish to live in, never add tap water directly to the tank. You need to de-chlorinate it first. You can also add a water treatment to help keep the water healthy between changes.

You should change about 10-15% of the water each week to keep it clean and healthy for the fish. Never do a full tank change once your fish are in the tank.

Choosing your fish

When you choose your fish, make sure you start introducing them slowly – this will help you identify if you’ve got the water balance right, and at this point, your tanks eco-system is still developing, so adding lots of fish can damage it.

There’s a wide range of tropical fish to choose from – Cichlids, Betta and Swordtails are good starter fish, and are nice to look at. Never mix goldfish and tropical fish together.
