Referred to scientifically as Xiphophorus helleri, this fish is very popular in community aquariums. In the wild, these fish normally have olive-green bodies with red stripes. Native to Central and North America, these fish were first discovered and then named in 1848.

The Swordtail Fish is one of the most common Swordtails, and is usually found in variations of red or green, leading to the creation of the specific Green and Red Swordtail Fish breeds. All Swordtail Fish look not unlike Platy fish and Guppies, but they usually have bulkier bodies. In addition, these fish have “swords’ that stick out from the bottom of the male’s tail fin.

Swordtail Fish are found in the Atlantic slopes of southern Mexico all the way to northwestern Honduras. In addition, they are now found in a number of countries in south Africa and Australia as the result of human introduction.

They are found in all kinds of waters, preferring areas that are heavily vegetated. Typically, they are found in canals, warm springs, and ponds.

Swordtail fish are not large freshwater fish species, but they aren’t the smallest you’ll find, either. Growing only to about 6 inches in length, the females of this species are larger than the males, who only grow to about five and a half inches.

There are all kinds of Swordtails, including the Montezuma Swordtail, the Delicate Swordtail, the Mountain Swordtail, and the Pygmy Swordtail. These fish are fast-growing and have beautiful dramatic “sword”-tails, as the name implies.

In the wild, these fish live in groups but do not exhibit schooling behavior. They will often group together in an aquarium, so it’s a good idea to keep multiple fish in your tank. These fish are incredibly hardy and can survive in a range of environments – meaning they can tolerate any small mistakes you might make when you are first getting started!

As medium-sized fish, these creatures do not need extensive amounts of space. However, they can be quite active, so while decorations are fine to have in your tank, it’s important that you leave plenty of open swimming space.

Ideally, the minimum amount of tank space you should for an adult swordtail is at least 15 gallons. If you intend to add more fish, you need to double that number – make it at least 30. These fish are great jumpers, so in addition to providing plenty of swimming space, you will also want to put a tight-fitting lid on your tank. There would be nothing worse than coming home to see your poor Swordtail Fish lying motionless on your living room floor!

These durable tropical fish can endure a wide range of water conditions. In terms of temperature, they have a large range- anything between 65 and 82 degrees Fahrenheit is fine. Nevertheless, you should try to avoid rapid fluctuations in temperature, as this can cause your fish serious stress and illness.

Swordtail Fish prefer waters that are relatively hard, with a rating of 12 to 30 dGH. The pH should be between 7.0 and 8.4. These fish like waters that are somewhat alkaline.

You should put special systems in place to make sure your tank is appropriately filtered. Install a filtration system before you introduce your fish, as this will keep your water parameters level and secure. You should also conduct weekly water changes of at least ten percent to keep your fish healthy and happy.

Swordtail fish eat many types of food. In the wild they are omnivores, so when you raise htm in captivity you can feed them just about anything. The best foods are high-quality flake food and live options like bloodworms, brine shrimp, fruit flies, daphnia, and mosquito larvae.

These fish also eat lots of algae and vegetation in a natural habitat. While they will usually leave the plants in your tank alone, it’s a good idea to give them some kind of a plant-based supplement to meet their dietary needs. An algae wafer is the perfect option to help meet this need.

Swordtail Fish Tank Mates

Swordtail Fish are active, yet peaceful, species. They aren’t shy and will instead appreciate having some company in the tank. You might consider housing them with passive species like others swordtails or even related species like mollies, platies, or angelfish.

Many people keep their Swordtails with corydoras, too. You will want to make sure these fish are peaceful, but otherwise, they usually won’t bother your Swordtail Fish as they occupy different levels of the water column. There are some types of tetras you can keep with your Swordtail Fish, too, but you need to make sure they are large and are kept in schools of at least five to prevent aggression.

You should always try to keep your Swordtail Fish with other fish of their own kind, too. This will help them feel the most at home. It’s important to maintain a good female-to-male ratio – ideally, you should only have one male to every four females. You may be able to get away with just three, but four will definitely be more ideal. This will prevent the males from harassing the females, as the somewhat aggressive behavior will be spread out among multiple females.

It should also be noted that male Swordtail Fish will be more aggressive toward other males within these pieces. If you don’t have a large tank, you might want to consider only raising one male Swordtail.

Maintaining consistent water parameters and avoiding rapid fluctuations in water temperature or pH can help keep your fish stable.
