Can Koi and Arowana Live Together in a Pond?

Yes, both fish can live together. However, the best way to ensure that your Koi and Arowana can live in a pond together is to make sure the two species are the same size, or that the Koi is larger than the Arowana.

Having the same size is best because neither fish will be intimidated or attack the other. Arowana is carnivorous and therefore these fish will view smaller fish as food. However, a large enough pond with lots of vegetation and plants should help prevent any attacks from occurring between the two types of fish.

Koi naturally live in a school and normally swim together therefore they should be placed with more than one fish. To prevent bullying of weaker fish or for the Koi to just feel happier, it is recommended that you place at least two Arowanas of the same kind in your pond.

Can Arowana live in a pond?

Yes, Arowana is normally found in a large body of water rather than ponds, but it is possible for Arowana to live in a pond.

It is because Arowana can live in low oxygen water which means they are not very strict on the type of environment that they need to survive. As long as you provide them with high-grade fish food, and clean their habitat properly then your Arowana will have no problem living in a pond. 

If you think about it, Arowana is really similar to Koi. Koi fish is known for their ability to thrive in low oxygen water which means they can live in a pond environment. So, Arowana should have no problem living in a smaller body of water such as a pond as long you provide them with all the necessary needs that they need to survive and thrive.

In fact, you can also combine Arowana with your Koi fish in a pond because both fish are known for being hardy and can live in low oxygen water.

If you want to make sure that your Arowana will have enough space to survive then it might be better if you put them in a small pond rather than in a large pond. This is because Arowana can grow really big and if you put them in a large pond then they might end up feeling claustrophobic and at the same time, you will also need to invest a huge amount of money on their food supply if they are going to be living in a big body of water.

Can a few Arowanas be kept together in a pond?

Yes, they can be kept together IF you have a large pond.

Arowana is very territorial, with strong aggression towards the same species and its own reflections, they can easily start fighting and killing each other even when there are equal numbers of them. This is especially true for male Arowanas. It’s a terrible sight to see surviving fish with their scales damaged and fins torn.

If you have more than one Arowana in the same pond, you should at least have a few big fishes (or Koi) sharing the same water space with them as they can be very aggressive towards other species too. If there are no bigger fish or Koi in the pond, it is very likely that Arowana will dominate the Koi and it will not hesitate to kill them.

So, it is not advisable for those who want to keep just Arowana or a few Arowanas in the same pond.

Can Arowana live with goldfish in my pond?

Yes, the Arowana can live with the goldfish. When the Arowana is still small, and you also have the goldfish in your pond, make sure that the goldfish will not be an easy snack for him/her. The Arowana fish can grow up to 1 m or more depending on the species. They are carnivores by nature so they just love anything fleshy-looking, whether it’s the goldfish or frogs, they just eat everything.

They have a very long and sharp mouth, and they will swallow their prey in one piece. Therefore if the goldfish are still small (around 2″ or less), then it’s not safe to put them together with your Arowana fish. But be sure that you won’t leave them unmonitored or whenever you’re not home. If the Arowana had a chance to catch and swallow up your goldfish, then there’s nothing you can do anymore.

But be sure to buy both of them when they are small. That way they will have a chance to grow up together.

In Conclusion

Ponds are a great way to add a little nature to your backyard.

Koi and Arowana can live together in the same pond because they require similar conditions. The ponds in which they are found typically contain low oxygen water, so while the Koi need to be given fresh running water occasionally to stay healthy, both will have no problem living in low oxygen water.
