Yes, goldfish can live alone. Even when they are kept alone, they live a long and healthy life if they get good nutrition and a clean environment. However, it’s a good idea to keep goldfish with other fish. They will benefit from the interaction and companionship and will live happier lives.

To evaluate when and how to keep goldfish with other tank mates, let us explore the characteristic traits and needs of this creature in closer detail.

Do Single Goldfish Get Lonely?

Goldfish are peaceful, community fish. Although they are not schooling fish, they enjoy the company of other fish.

When kept in groups, these fish continuously interact with each other.

However, goldfish can do just fine on their own.

A single goldfish will perform the same activities every day without displaying signs of loneliness.

Factors To Consider When Keeping Other Fish With Goldfish

Given below are the various factors that you should consider while keeping your goldfish with other fish.

Water Temperature

The habitat needs of a fish will depend on the type of species and where it originates from.

Tropical fish do best in temperatures above 75°F, while cold water fish need lower temperatures of 70°F or less.

In the wild, fish can move to a more comfortable microenvironment if there is any change in temperature or water condition.

However, this is not possible in a small aquarium.

So, you should maintain consistent and correct temperature conditions for your goldfish to survive and grow.

When adding other fish to your goldfish tank, choose species with similar temperature needs.

Common varieties of goldfish need temperatures between 60°F and 70°F while the fancy varieties prefer 68°F to 74°F.

Water pH

Your fish may have originated in a pond, stream, river, lake, or ocean.

The pH level of each of these water bodies is different. So, no single pH applies to all fish by default.

Nonetheless, it is an important parameter. Fish that are young or ill are susceptible to pH changes.

Additionally, breeding occurs only at a specific pH in some fish.

Goldfish thrive in water with pH levels between 7.4 and 8.

Find fish with similar pH level requirements to keep with your goldfish.

An easy way to determine this is to check whether the fish originated in similar habitats.

Size Of The Fish

Fewer problems are likely when all the fish in an aquarium are of similar size.

So, it is unwise to keep goldfish with smaller fish. Goldfish will also feed on fish fry and eggs.

So, it is a threat to other inmates of the tank and their offspring.

Remember that the fish you bring home from a pet store will not be fully grown.

Make sure that their size will be similar when they achieve full growth to ensure compatibility.

Tank Size

You will need a bigger tank when you have more than one fish.

Since each fish will need a lot of water to swim, a big aquarium is always the better choice.

Overcrowding will restrict freedom and limit the growth of your fish.

So, avoid adding more fish that the tank can comfortably accommodate.

Another factor to consider is that goldfish are very messy. Their waste causes the ammonia levels in the tank to rise.

You will have to frequently change the water or invest in a filter to ensure that the water quality is maintained.

When keeping more than just one goldfish, you will have to clean the tank more often or use a strong filter.

Goldfish grow considerably big. It needs a big space to swim comfortably.

Additionally, the growth of a goldfish is restricted by the size of its enclosure.

Make sure that the tank has enough space to accommodate as many fish as you decide to keep.
