To determine which fish are able to share a pond with koi carp, it is first important to consider the characteristics of koi and their environmental requirements.
Koi carp?are ideal for ponds that have a large capacity, plenty of cover and an efficient filter system. They require excellent?water conditions and only thrive in large, deep ponds. They are very resilient and can withstand winter in a frozen pond, as long as you provide and maintain an air stone or floating heater to promote exchange of gases.

Koi are descendants of the common carp, and normally reach 36 inches and weigh as much as 35 pounds when fully grown. They were originally raised in rice paddies by Japanese farmers; with mutation, slight variations in color soon developed. Through selective breeding over the centuries, certain colors and patterns like Orenji, Doitsu and Midori developed.

So, given their size and habitat, what species of fish can safely share a pond with koi carp?

-Orfe thrives well in ponds with efficient filter system and well oxygenated

-They are sociable fish and should be kept in schools of at least three

Sturgeon moves the bottom surface about more as it hugs the bottom

It?s?irregular body?movement disturbs the muck at the bottom of the pond?and this gives the pump a chance to get it to filter

Koi and catfish can live in harmony for a while, but as the catfish grow they may damage or kill the koi.

-Contribute to the pond load

-Bottom feeder

– tend to kick up a lot of bottom debris, which can lead to cloudy, murky pond water

Keeping exotic fish as pets 0 1959

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.
