Are you looking to add some tank mates to your goldfish aquarium? You’ve come to the right place!

Here, we’ll discuss 14 of the best fish that can live harmoniously with goldfish. From platies to bristlenose plecos, these fish all make great additions and will bring plenty of color and activity to your tank.

Let’s get started!

Key Takeaways

  • Peaceful tank mates for goldfish include platies, Corydoras catfish, mollies, and white cloud mountain minnows.
  • Peaceful tank mates should have similar water conditions, a peaceful temperament, and need plenty of swimming space and plants for hiding/breeding.
  • Tank mates should be checked for compatibility with goldfish and fed flakes or freeze-dried foods designed for small fish. They also require cooler water and more space for swimming.
  • Peaceful tank mates help maintain the balance of the tank by eating algae, add vibrant color and movement, promote healthier water quality, and contribute to a happy ecosystem in the aquarium.


Platies are a great choice to serve as goldfish tankmates. They prefer similar water conditions and have peaceful temperaments.

When it comes to tank setup, platies do best in tanks with plenty of swimming space and plants for hiding/breeding. Furthermore, they can be encouraged to breed by providing the right conditions – caves, clean water, and vegetation – which can add an extra element of fun to your aquarium!

Corydoras Catfish

Corydoras catfish are a popular choice for aquariums because they’re peaceful and active. They thrive in tanks with plenty of hiding spots and require medium-soft water conditions.

Corydoras breed in a wide variety of tank sizes, from 10 to 40 gallons. To create an ideal aquarium setup, provide live plants and driftwood or rocks for them to hide under.

Breeding habits vary among species, so it’s important to do your research before introducing them into the tank.


Mollies are a popular choice for freshwater aquariums. There are many species to choose from, and they’re easy to care for. They can thrive in a range of temperatures. Dietary requirements vary by species, but they typically enjoy live foods like plankton or worms.

Mollies are peaceful and make great tank mates. They’ll add vibrant color and bring life to your aquarium!

White Cloud Mountain Minnows

Are you considering White Cloud Mountain Minnows (WCMM) for your goldfish tank? WCMM are a great addition if they are compatible and properly fed.

You should check with an expert to make sure they will get along with your goldfish before adding them.

Once that is taken care of, make sure to feed them flakes or freeze-dried foods specifically designed for small fish like WCMM.

With the right combination of tank mates and food, the WCMM can be a great addition to your aquarium!

Compatibility: Is WCMM Compatible With Goldfish

You’ll want to be sure that your White Cloud Mountain Minnow (WCMM) is compatible with goldfish before adding them to the same tank. To ensure their compatibility, consider the water temperature and size of the tank.

WCMM prefer cooler water than Goldfish so a larger tank may be needed for both species to thrive. Additionally, because WCMM are active swimmers, they need more space than Goldfish do in order to remain healthy and happy.

With these factors in mind, it’s possible for WCMM and Goldfish to co-exist successfully in one aquarium.

Feeding: How to Feed Wcmm?

You’ve determined that WCMM is compatible with goldfish, so now it’s time to think about their feeding habits and tank setup.

Feeding should be done two or three times a day, using only as much food as the fish can consume in a few minutes. Make sure to provide them with a variety of foods like flakes, pellets, and frozen treats.

It’s important to keep an eye on the inhabitants of your tank and adjust the amounts accordingly.

Siamese Algae Eaters

Siamese Algae Eaters are a great addition to any goldfish aquarium. They’re omnivorous, peaceful, and originate from Southeast Asia.

These fish can help maintain the balance of your tank by eating the algae that accumulates on rocks and plants.

Plus, they add vibrant color and movement to your tank, making it an even more enjoyable environment for you and your fish!

Diet: Omnivorous

When choosing a goldfish tank mate, it’s important to consider its diet. An omnivorous fish will eat both plants and animals. An omnivore helps keep the water clean by scavenging for leftover food and waste, promoting healthier water quality.

Dietary requirements should be balanced, with the right mix of proteins, vegetables, and other nutrients in their diet. Feeding your fish a variety of foods will help ensure they stay healthy and active.

A well-rounded diet is essential to keeping a happy and healthy tank atmosphere.

Behavior: Peaceful

When selecting a tank mate for your fish, it’s important to consider their behavior. Ideally, you’ll want a peaceful variety that won’t cause any distress or aggression.

When looking at tank mates with peaceful coexistence, consider species like neon tetras, zebra danios, and white cloud mountain minnows. These fish have an easygoing nature and can be kept in groups of five or more within the same tank.

Social dynamics are also key when considering a tank mate. Larger fish should not be mixed with smaller ones as they may mistake them for food!

Allowing your fish to peacefully coexist will ensure their health and happiness in the aquarium.

Origin: Southeast Asia

Many of the most popular aquarium fish originate from Southeast Asia, including some of your favorite varieties. Fish care and water quality are key elements in successfully keeping these breeds.

To ensure a healthy habitat, make sure to research the specific needs for each species before adding them to your tank. With proper attention and good maintenance, you can enjoy a thriving aquarium with stunning inhabitants from Southeast Asia!

Bamboo Shrimp

Bamboo shrimp are an ideal tank mate for goldfish because they don’t require direct feeding. They survive off the detritus in the aquarium.

When it comes to breeding habits, bamboo shrimp prefer a tank setup with plenty of caves and hiding spots. They breed easily, so it’s important to keep their numbers in check to prevent overcrowding.

A great benefit of having bamboo shrimp in your tank is that they help keep the water clean. They consume excess food and debris, which helps maintain water quality.

Overall, bamboo shrimp make a peaceful addition to any goldfish aquarium!

Ghost Shrimp

Ghost shrimp are a great addition to many freshwater setups. They don’t require much care and can help clean up the tank. The size of your tank will determine how many ghost shrimp you can have.

Ghost shrimp are active scavengers that feed on leftover food and algae in the tank. They’re peaceful and sociable creatures that add life to any aquarium setup!

Despite being very peaceful, they can be skittish with bright lights or sudden movement in the aquarium. Therefore, it’s important to provide adequate hiding spots for these fish in order to reduce stress levels.

Harlequin Rasboras

Harlequin rasboras are a lively and colorful addition to any freshwater community, making them a great choice for beginners. These little fish don’t require much from their environment. They do best in tanks of 10 gallons or more with neutral pH water and temperatures between 72-78°F.
