Do Koi Carp Sleep? 0 861

One of the most common questions we get asked is “do koi carp sleep?”. You may assume that koi do sleep at some point; but is that correct? And, if so, how do koi sleep? How often do they sleep? And how can you tell they are sleeping? Read on to learn more…

What do we mean by sleep?

When we think of sleep, we generally mean a period of inactivity where we close our eyes, relax our bodies and lose consciousness as our brains and bodies refresh themselves.

Dreaming and the different stages of sleep are an important part of this, and the sleep of mammals goes through distinct cycles before we wake up in the morning.

The differences between fish and mammals

Koi carp are not mammals, and so, sleep for them is not the same thing! Fish such as koi carp do not have the same higher-level brain functions that mammals do, and so they do not and cannot follow a similar type of sleep process to us, and as far as we know, they do not dream.

Do koi carp sleep?Another way in which koi sleep differs from human sleep is that koi do not close their eyes. This is because they can’t, as koi don’t have eyelids!

Ultimately, there is some debate among fish experts over whether or not the resting and rejuvenation process of fish like koi carp can genuinely be viewed as “sleep” or simply as deep rest. But one thing we can be sure of is that koi do go through cycles of very limited activity on a daily basis, where it is fair to say that they are at least deeply resting, if not actually “asleep”.

Brain function and resting

You can often tell when your koi are undergoing a rest cycle by watching their activity levels. When at rest, koi will float still in one spot of the pond for a long period of time, usually in the middle or near the bottom of the pond in order to avoid exposing themselves to predators.

Cold weather also has an effect on koi, and they may, in extremes of cold, go through a process of semi-hibernation, where their metabolic rate slows right down, they do not feed, and they will retreat to the bottom of the pond to wait out the cold snap. When the weather warms back up again, they will come “back to life” and resume feeding as normal.

Keeping exotic fish as pets 0 530

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.
