There are hundreds of fish that can live with goldfish, so if you’re looking for new fish to add to your goldfish tank, there are plenty to choose from.
However, not all fish will make the best goldfish tank mates.
Every type of fish has different needs. For instance, some fish like warm water, others like cold water, some like saltwater, others don’t. Because you’ll want all of your fish to be healthy and happy, it’s important to choose tank mates that like similar tank conditions.
Tank conditions for fish to live with goldfish
Goldfish are freshwater fish that like a temperature of 65 – 80 °F, so fish that live with goldfish should like this setup too. But temperature is just one factor to consider.
In addition, some things to think about include:
- Is your tank big enough for all the fish? You can find the minimum tank size needed for the goldfish alone, using our goldfish tank size calculator.
- Will the other fish nip your goldfish’s fins?
- Could the other fish suck on your goldfish’s scales?
- Might the fish chase each other around the tank?
- Could the goldfish try to eat the other fish?
- Will either fish out-compete the other for food?
- What are the risks of adding new fish to a tank?
- Will the fish look good together?
We look at all of these factors more closely in our guide to keeping other fish with goldfish.
What fish can live with goldfish?
Our experts have given this some serious thought and have come up with an ultimate list of 21 possible goldfish tank mates.
This list generally assumes that we are talking about fancy goldfish, living in an aquarium. This is because fancy goldfish are slower moving and therefore less likely to bother their tank mates.
However, some fish on this list may also live with small (i.e. young) slim-bodied goldfish, as they are less likely to be able to eat their tank mates due to their small mouths.
Larger slim-bodied goldfish are best kept in a pond, which presents different challenges and requirements.
So, what fish can live with goldfish? We’ll start with our top two choices, then list fifteen other options. And finally, for those of you looking for something a bit different, we suggest four tank mates that aren’t even fish!
The best goldfish tank mates
Our top two fish that can live with goldfish are
These are two very different types of fish, so whatever you’re looking for – and however your tank is set up – chances are one of these will work for you.
Let’s look at them more closely.
Temp: 70 – 80 °F | Max Size: 5 inches
Bristlenose Plecos are much smaller than Common Plecos, which can grow up to 15 inches. Therefore, Bristlenose Plecos fall into a useful sweet spot of being small enough to fit into many goldfish tanks, without being so small that goldfish can eat them.
Choosing a Pleco to live with your goldfish comes with a big advantage too: Plecos love to eat algae, so will keep your tank nice and clean!
And while some Plecos have been known to suck on goldfish scales – often causing serious injury – this issue is very rarely reported with the Bristlenose Pleco.
Pros of keeping Bristlenose Plecos with goldfish:
☑ Unlike other Plecos, Bristlenoses don’t usually suck on goldfish scales.
☑ Bristlenose Plecos will eat algae from your tank, which keeps it clean.
☑ They generally stay near the bottom of the tank, adding interest to an area that might otherwise be empty.
Cons of keeping Bristlenose Plecos with goldfish:
✖ Bristlenose Plecos don’t usually suck on goldfish scales. However, there is always a risk that your particular Pleco may decide to!
✖ Bristlenose Plecos are pretty big fish – up to 5 inches – so you will need plenty of room for both your Plecos and your goldfish.
Temp: 64 – 77 °F | Max Size: 3 inches
Platies (or ‘Platy Fish’) are small livebearers that come in a wide range of colours.
Platies breed relatively easily and can give birth to dozens of fry (babies) at a time. However, you won’t need to worry about your goldfish tank becoming overrun. This is because all of the fry are likely to be eaten by your goldfish and the Platies themselves. (Needless to say, if you can’t bear to see this happen, you need to stop them breeding or accept that Platies may not be the fish for you!)
Though it might seem strange to recommend a small livebearer for a goldfish tank, Platies are chunky enough to avoid being eaten. They’re also placid and unlikely to nip at your goldfish.
Pros of keeping Platy Fish with goldfish:
☑ Platy Fish are peaceful, so very unlikely to nip at your goldfish.
☑ They are small, but usually big enough to not get eaten.
☑ Platies are easy to care for.
☑ Platies are available in lots of patterns and colors.
Cons of keeping Platy Fish with goldfish:
✖ Platies grow to a maximum size of 3 inches, so they are just about big enough for most goldfish to not view them as a potential snack. However, if you have large goldfish and small Platies, please do be careful!
Good goldfish tank mates
Generally speaking, the fish listed below will live quite happily in an aquarium with fancy goldfish.
That’s why we’ve called them “good” goldfish tank makes. In other words, they’re not perfect, but they should be fine.
Please do read carefully though. Choose the best fish for your own situation, and be ready to remove the new fish from the tank if there are any problems.
Black Skirt Tetra
Temp: 68 – 78 °F | Max Size: 3 inches
Pros of keeping Black Skirt Tetras with goldfish:
☑ Black Skirt Tetras are hardy and easy to care for.
☑ They’re fast, so can out-run goldfish if necessary.
☑ Like the Platy, Black Skirt Tetras are usually too big for goldfish to try to eat.
Cons of keeping Black Skirt Tetras with goldfish:
✖ You’ll need room in your goldfish tank for a school of six or more Black Skirt Tetras.
✖ They’re not always the most lively fish.
✖ There is some risk of Black Skirt Tetras nipping goldfish fins.
Temp: 64 – 82 °F | Max Size: Just over 2 inches
Pros of keeping Bloodfin Tetras with goldfish:
☑ Bloodfin Tetras are hardy, so good for beginners.
☑ They’re also fast, so can out-run goldfish if necessary .
Cons of keeping Bloodfin Tetras with goldfish:
✖ You’ll need enough room in your goldfish tank for a school of at least 5 Bloodfin Tetras.
✖ There is some risk of Bloodfin Tetras nipping goldfish.
✖ At just over 2 inches, Bloodfin Tetras are only just large enough to safely live with goldfish.
Temp: 68 – 75 °F | Max Size: 2 inches
Pros of keeping Checker Barbs with goldfish:
☑ Checker Barbs are a placid fish that is a good fit for community tanks.
☑ They are fast, so can out-run fancy goldfish, which tend to be slow swimmers.
Cons of keeping Checker Barbs with goldfish:
✖ At around 2 inches, Checker Barbs are only just large enough to safely live with goldfish. Therefore, there is some risk of larger goldfish attempting to eat Checker Barbs.
✖ You will need enough room for not just one, but a school of Checker Barbs.
Temp: 60 – 75 °F | Max Size: 2.5 inches
Pros of keeping Corydoras Catfish with goldfish:
☑ Corydoras will hunt out food scraps at the bottom of the tank, eating them rather than leaving them to rot, which helps keep your tank clean
☑ They are very peaceful and certainly won’t give your goldfish any trouble. However, the reverse may not necessarily be true.
Cons of keeping Corydoras Catfish with goldfish:
✖ As your Corydoras live at the bottom of the tank, you may struggle to feed them without their food being grabbed by your goldfish first.
✖ Corydoras are a schooling fish, so you will need room to keep a small group together.
✖ As with other smaller fish on this list, there is a chance that goldfish will attempt to eat them.
Temp: 72 – 75 °F | Max Size: 4 inches
Pros of keeping Giant Danios with goldfish:
☑ Giant Danios are large enough to avoid being eaten by goldfish.
☑ They are fast and active, which means they will stay out of trouble and add plenty of interesting activity to your tank.
Cons of keeping Giant Danios with goldfish:
✖ Giant Danios grow to 4 inches and should be kept with other Giant Danios, so you will need a large tank.
Temp: 64 – 75 °F | Max Size: 3 inches
Pros of keeping Gold Barbs with goldfish:
☑ Gold Barbs are hardy and easy to care for
☑ They have a fantastic golden color that will brighten up any aquarium.
Cons of keeping Gold Barbs with goldfish:
✖ Barbs can have a tendency to be territorial and nip goldfish fins. This is usually less of a problem with Gold Barbs than with some other types (such as Tiger Barbs), but it is still a risk.
✖ You will need room for at least 5 Gold Barbs, as well as your goldfish.
Temp: 61 – 75 °F | Max Size: 3 inches
Pros of keeping Hillstream Loaches with goldfish:
☑ Hillstream loaches are generally peaceful, though may defend their territory or source of food.
☑ Loaches will help to keep your tank clear of algae.
Cons of keeping Hillstream Loaches with goldfish:
✖ It may be difficult to ensure your loaches get enough food without it being snapped up by the goldfish first.
✖ Your tank will need an area of fast-flowing water. Your loaches will enjoy this, but your goldfish might not!
Japanese Rice Fish
Temp: 65 – 75 °F | Max Size: 1.5 inches
Pros of keeping Japanese Rice Fish with goldfish:
☑ Japanese Rice Fish are an ideal ‘starter fish’ for beginners, similar to the White Cloud Mountain Minnow.
☑ Although you should keep Japanese Rice Fish in groups of six or more, they are small enough to not take up a huge amount of tank space
Cons of keeping Japanese Rice Fish with goldfish:
✖ At just one and a half inches long, Japanese Rice Fish are at risk of getting eaten by goldfish – if the goldfish can catch them.
Murray River Rainbow Fish
Temp: 71 – 78 °F | Max Size: 4 inches
Pros of keeping Murray River Rainbow Fish with goldfish:
☑ Murray River Rainbow Fish are a very colorful fish that will brighten up any goldfish tank.
☑ They are very hardy and therefore low maintenance.
☑ They are peaceful fish and therefore unlikely to harass goldfish or any other tank mates.
Cons of keeping Murray River Rainbow Fish with goldfish:
✖ You will need enough space for at least three, preferably more, Murray River Rainbow Fish in your tank.
Temp: 64 – 72 °F | Max Size: 6 inches
Pros of keeping Rosy Barbs with goldfish:
☑ Rosy Barbs are another great choice for any goldfish-keeper looking to add color to their aquarium.
☑ Rosy Barbs are very active fish and will provide plenty of interest and entertainment.
Cons of keeping Rosy Barbs with goldfish:
✖ At up to six inches long – and as a schooling fish – you will need a very large tank to keep both Rosy Barbs and goldfish.
Temp: 70 – 78 °F | Max Size: 4 inches
Pros of keeping Rubberlip Plecos with goldfish:
☑ Rubberlip Plecos are much smaller than the Common Pleco, which makes them far better suited to a community tank.
☑ They have similar environmental requirements to goldfish.
☑ Rubberlip Plecos are quite placid, non-aggressive fish.
Cons of keeping Rubberlip Plecos with goldfish:
✖ While they are generally not aggressive, Rubberlip Plecos are physically capable of sucking on goldfish scales, which means there’s always a risk of serious injury to your goldfish.
Temp: 73 – 77 °F | Max Size: 5 inches
Pros of keeping Scissortail Rasboras with goldfish:
☑ Scissortail Rasboras are a placid fish that does well in community tanks.
☑ Their streamlined bodies contrast well with fuller-bodied fancy goldfish, so they are a good aesthetic choice.
☑ Scissortail Rasboras have interesting tail patterns and a brilliant silver sheen.
Cons of keeping Scissortail Rasboras with goldfish:
✖ Your tank will be need to be quite warm, in the region of 73 – 77 °F.
✖ Scissortail Rasboras are a five-inch-long schooling fish, so a large tank will be required to keep six or more with goldfish.
Weather Loach (aka Dojo Loach)
Temp: 45 – 77 °F | Max Size: 11 inches
Pros of keeping Weather Loaches with goldfish:
☑ Weather Loaches are fascinating creatures. For instance, did you know they can survive for HOURS out of water?
☑ Weather Loaches are friendly, social fish that do well in a community, as long as they have enough space and are not housed with aggressive tank mates.
Cons of keeping Weather Loaches with goldfish:
✖ Weather Loaches are BIG – growing up to eleven inches.
✖ You’ll want to keep three or more Weather Loaches so will need a really big tank. Ideally, the tank should be wide as well as long, to give the Weather Loaches plenty of room to explore.
✖ Weather Loaches like to burrow in sand or small round gravel, which you may not want in your goldfish setup.
White Cloud Mountain Minnow
Temp: 45 – 75 °F | Max Size: 1.5 inches
Pros of keeping White Cloud Mountain Minnows with goldfish:
☑ A small fish, but still interesting, with a bit of color. It is easy to keep a group of six or more White Cloud Mountain Minnows without the need for a huge tank.
☑ White Cloud Mountain Minnows are fantastic beginner fish, as they are extremely hardy.
Cons of keeping White Cloud Mountain Minnows with goldfish:
✖ Though we have included White Cloud Mountain Minnows on this list, at just one and a half inches long, there is a real risk that they may get eaten.
✖ Remember – your goldfish attempting to eat a Minnow isn’t just dangerous for the Minnow, it’s dangerous for the goldfish too, as they could choke.
Temp: 65 – 78 °F | Max Size: 2 inches
Pros of keeping Zebra Danios with goldfish:
☑ You’re spoilt for choice when it comes to Zebra Danios. Colour varieties include Gold, Albino and Blue Danios, and you can get Long-finned Danios too. There are even Leopard Danios which – as the name suggests – have spots instead of stripes!
☑ As a similar fish to White Cloud Mountain Minnows (above), Zebra Danios share the benefits of being a small but interesting fish that can cope with a wide variety of water conditions.
Cons of keeping Zebra Danios with goldfish:
✖ Although they are usually okay, there have been reports of some Zebra Danios nipping goldfish fins.
Animals other than fish that can live with goldfish
We’ve looked at what fish can live with goldfish… but what about tank mates that aren’t fish?
If you’re looking for something a little different, one of these four options might just be for you.
Temp: 64 – 82 °F | Max Size: 6 inches
Pros of keeping Apple Snails with goldfish:
☑ Their size and shell keeps them safe from goldfish. Usually, goldfish will investigate the Apple Snail but stop bothering it once they realise it’s not food.
Cons of keeping Apple Snails with goldfish:
✖ Apple Snails may not be as active in cooler goldfish tanks.
✖ Apple Snails like to eat a lot and may eat your plants. You may therefore want to use fake plants (or none at all) if you’re going to keep an Apple Snail.
Temp: 60 – 64 °F | Max Size: 10 inches
This is more of a technically possible animal to keep with fancy goldfish, as opposed to a recommendation. We’d generally recommend keeping an axolotl as a pet in a tank of its own.
Pros of keeping an Axolotls with goldfish:
☑ Axolotls won’t usually bother goldfish, and if the goldfish bother them, they will nip back. This often results in a stalemate, where the goldfish and Axolotls live peacefully.
☑ Look at them! Axolotls are fascinating creatures!
Cons of keeping an Axolotls with goldfish:
✖ The ideal temperature range for Axolotls (60 – 64 °F) lies just outside our minimum recommended temperature for goldfish, which is 65 °F.
✖ Any significant water flow in its tank may lead to your Axolotl becoming stressed.
✖ Unlike most fish on this list – which are at risk of being eaten by your goldfish – in this case, smaller goldfish are at risk of being eaten by the Axolotl!
✖ Axolotls are large, so you’ll need a very big tank to keep them with goldfish.
Temp: 68 – 85 °F | Max Size: 4 inches
Pros of keeping Bamboo Shrimp with goldfish:
☑ Bamboo Shrimp are larger than Ghost Shrimp, below, which will help them to avoid being eaten.
☑ If you provide plenty of hiding places, your shrimp will usually stay hidden and keep well away from your goldfish.
Cons of keeping Bamboo Shrimp with goldfish:
✖ Even if they don’t succeed, there is a chance that your goldfish will try to eat your Bamboo Shrimp, which can cause the shrimp a lot of stress.
Temp: 72 – 82 °F | Max Size: 2 inches
Pros of keeping Ghost Shrimp with goldfish:
☑ Ghost Shrimp’s transparency can help them to hide from goldfish, though you should still provide plenty of good hiding spots too.
Cons of keeping Ghost Shrimp with goldfish:
✖ As with Bamboo Shrimp, above, the main problem with keeping Ghost Shrimp and goldfish together is the risk of your shrimp being eaten by your goldfish.
