Can Swordtail Fish Live With Goldfish?

Yes, swordtail fish can live with goldfish. Both species are compatible in terms of water parameters (temperature, pH and hardness). Swordtails get along well with other peaceful community tank mates such as guppies and mollies.

However, swordtails may become aggressive towards each other or smaller fish if they are overcrowded so it is important to provide adequate space for the fish to swim around freely. Swordtails should not be housed with larger predatory fishes such as cichlids which could bully them or even eat them. Goldfish on the other hand should not be kept with small tropical fish since their dietary needs are different and they produce large amounts of waste that affects the quality of water in an aquarium.

As long as both species have enough space and a suitable environment they will peacefully coexist together in an aquarium setting.

Swordtail fish can be a great addition to any goldfish tank, as they are both hardy and easy to care for. Swordtails can thrive in the same water conditions that goldfish prefer, and their naturally peaceful temperaments make them ideal tank mates. They add a splash of vibrant color with their long flowing tails and fins that are often adorned with various hues of reds, oranges, greens, yellows and blues.

As long as your goldfish aquarium is large enough to accommodate both species comfortably, it should provide an excellent home for swordtail fish and goldfish alike!

Can Angelfish Live With Goldfish

Angelfish and goldfish may look similar, but they are not compatible tankmates. Goldfish require cold water temperatures while angelfish prefer warm waters, making it difficult to create an environment that meets both fish’s needs. Additionally, goldfish produce more waste than angelfish and can quickly pollute the tank if overcrowded or under-filtered.

Therefore, keeping these two species together is not recommended for successful long-term care of either type of fish.

How Many Swordtails Should Be Kept Together

When considering how many swordtails to keep in an aquarium, it’s important to remember that swordtails are schooling fish. As such, they should be kept in groups of at least four or more for optimal health and well-being. Additionally, the tank size should be taken into account when determining how many swordtails can be comfortably housed together – a 20 gallon tank is suitable for up to 10 small fish like swordtails.

Swordtail Size

Swordtails can range in size from 3-5 inches, depending on the species. They are popular aquarium inhabitants due to their hardy nature and attractive color patterns. Swordtails can have both short and long fins, as well as an array of colors including yellow, orange, red, black and white.

Their maximum lifespan is around five years when kept in a healthy environment with plenty of space to swim and feed.

Swordtail Temperature

Swordtails are tropical fish, so they prefer waters with a temperature range between 72-82 degrees Fahrenheit. It is important to keep the tank at a consistent temperature and monitor it regularly as fluctuating temperatures can cause stress to your swordtail, which can lead to health problems. Additionally, if the temperature dips below 72F or rises above 86F for an extended period of time it can prove fatal.


Swordfish are a type of fish that can be found in tropical and temperate oceans around the world. They have an elongated, flat body shape with long, sharp bills and two dorsal fins. They are large fish that can grow up to three meters in length and weigh up to 180 kgs!

Swordfish are mainly carnivorous but also feed on squid, octopus and crustaceans. They use their sharp bills to slash at prey which stuns them so they can be eaten more easily. Swordfish is a popular seafood dish due its mild flavor and firm texture.

What Fish Can Live With Swordtail Fish?

Swordtails are a species of tropical fish native to Central America. They are peaceful, hardy and popular aquarium fish that can live with a variety of tankmates. Swordtail fish have an interesting social behavior and prefer to be kept in groups.

When it comes to compatible tankmates for swordtail fish, there are many options available. Popular choices include other peaceful schooling fish like Danios, Barbs and Tetras; as well as some larger semi-aggressive species such as Gouramis or Angelfish. Other suitable companions include Corydoras Catfish, Platies, Mollies and even Livebearers such as Guppies or Endlers.

It is important to ensure that the other species chosen all require similar water parameters (temperature, pH level etc) so they can coexist happily together in the same environment. Lastly, keep an eye on any aggressive behaviors from individual specimens which may lead them into conflict with their tank mates – if this occurs then you should consider rehoming one of the more aggressive individuals elsewhere!

Can Swords Live With Goldfish?

No, swords cannot live with goldfish. Swords are a species of fish that require cooler waters than the warmer aquarium tank temperatures needed by goldfish. Goldfish prefer temperatures between 65 to 72 degrees Fahrenheit while swords need water temperatures in the mid-70s or lower to thrive.

Additionally, swords can be quite aggressive and territorial and may bully any other fish they are kept with, including goldfish. As such, it is not recommended to keep these two species of fish together in the same tank as doing so could severely stress out your sword and/or lead to injury for both types of fish due to aggression from either side.

Can Swordtail Fish Eat Goldfish Flakes?

Swordtail fish are a type of tropical fish that can make an exciting addition to any home aquarium. They have striking coloration and a unique shape that makes them stand out among other types of fish. One question many people ask is whether swordtail fish can eat goldfish flakes.

The answer is yes, swordtail fish can safely eat goldfish flakes as part of their diet. Goldfish flakes provide the essential nutrients for your swordtails such as carbohydrates, proteins, lipids, vitamins and minerals; however some supplementation with frozen or live foods may be necessary in order to ensure proper nutrition for your swordtails. When providing goldfish flakes for your swordtails it’s important to remember not to overfeed them as this could lead to an unbalanced diet which could cause health issues down the line.

In general you should only feed them what they will consume within two minutes twice daily and remove any leftovers before they have time to decompose in the tank water. With proper care and nutrition, your swordtails should thrive while eating goldfish flakes!

What Fish Cannot Go With Goldfish?

Goldfish are one of the most popular and beloved pet fish, but not all fish can live harmoniously with them. Goldfish are coldwater fish, meaning they thrive in a temperature range between 65-72 degrees Fahrenheit. Many tropical or warm water fish require temperatures up to 84 degrees Fahrenheit and cannot survive when kept in water that is too cold for them.

Additionally, goldfish tend to be large compared to other aquarium species so it’s important to make sure any tankmates you choose don’t grow larger than your goldies or require more space than your tank allows. Goldfish also have strong suction mouths and will eat anything small enough for them to swallow—including their tankmates! This means some smaller species of fish such as guppies, small tetras, neon tetras and mollies should not be kept with goldfish.

Other territorial bottom dwellers like cichlids may attack and even kill peaceful goldfish if given the chance so it’s best avoid housing these two types together altogether. If you want an interesting mix of different colored finned friends in your aquarium then consider adding some white cloud mountain minnows instead; they stay relatively small (under 2 inches) thrive at cooler temperatures around 68–72°F (20–22°C), have similar dietary needs as the common goldie, plus they come in several pretty colors including reds & blues!

Oranda Power : goldfish and swordtail…could it work?


Overall, it is possible to keep swordtail fish and goldfish together in the same tank. While there are some risks associated with this type of combination, by taking a few precautions such as providing plenty of hiding spots for the swordtails and not overstocking the tank, these fish can make compatible companions. With proper care and maintenance, both species can live peacefully side-by-side in an aquarium environment.
