Do koi carp have teeth?Koi carp have teeth right at the back of their throats, not at the entrance to the mouth as you might expect. You will not be able to see your koi’s teeth simply by looking into their mouths, they’re too far back in their throats.

So how do koi carp eat?

Because koi usually feed from the bottom of their pond, their mouths are ideally shaped to allow them to pick up food from the pond floor. This positioning of the mouth on the underside of the head means that koi are referred to as “bethnic feeders” – though they are also capable of eating from the surface of the pond and the middle of the water too.

The teeth of the koi carp are next to the last arch of the gill. The teeth on the bottom plate point upwards towards a hard bony plate in the roof of the throat. This allows koi to crush their food and chew hard particles that they would not otherwise be able to digest.

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.
