The Swordtail is similar in shape to both the Platy and the Guppy though it has a bulkier body and a "sword" extending from the bottom of the male's tail fin. Today it is often thought to be named for this "sword" shaped extension of its tail fin, but the Swordtail was actually named for the sword like appearance of the male's anal fin!
A beautiful male sporting a "sword" tail is one of the most striking physical characteristic possible by any aquarium fish. Even though there is no apparent purpose for this tail, it is 1/4 to 1/3 the total length of the fish. The wild species have an even more majestic tail, with swords up to 6 inches (15 cm). Though the "sword" tail is shorter in tank bred specimens it is complimented by the wonderful colors that are now available.
Like the platys, swordtails have been interbred to produce all kinds of interesting colors and different types of finnage. Some of the more common Swordtails are: Red, Red Wag, Red Tux, Painted, Neon Green, Marigold (and wag), Pineapple, Black, Red Twin bar, Sunset, and Gold Tuxedo swordtails.
Extremely popular because they are one of the prettiest fish, the Swordtails are also easy to breed, fast growing and readily available.They are generally peaceful lively fish that swim in loosely grouped schools. Even though they are considered a good community fish, there are potentially many different behavior patterns and temperments. The individual fish vary from peaceful harmonious tankmates to bullies. Older males especially can tend to be aggressive toward each other and other species.
Swordtails do best in a well planted tank with lots of room to swim around. Provide floating plants to protect the young as the parents often eat their fry. Like all livebearers, they do like a bit of salt though it is not necessary.
The Swordtails are found in Central America from the Atlantic slopes of southern Mexico to Guatamala.
There are several color varieties of the Swordtail Xiphophorous helleri as well as a variety of other Swordtails species. The original Swordtail Xiphophorous helleri the most available and the other species, though similar, are not always as large and are often more delicate.
The Spotted Swordtail was introduced as early as 1864, while the popular Green Swordtail was first introduced in 1909.
Scientific Name: Xiphophorous hellerii
Social Grouping: Groups - Enjoys being with other swordtails even though it is not a schooling fish.
IUCN Red List: NE - Not Evaluated or not listed
Swordtails come in many colors and mixtures of colors, even in wild strains, that including red, green, black and albino though the most well known is red. There are now lyretail and high-fin varieties as males have been developed with exaggerated finnage and with two swords instead of one. Even some females also now have a sword. Most crosses are between the Platy or Moonfish Xiphophorous maculatus and the Swordtail Xiphophorous helleri.

Popular cross bred Swordtails:
The Green Swordtail has a green body with red and yellow along the lateral line of the sides. The Green Wagtail Swordtail is this fish crossed with a Wagtail Platy and the Green Tuxedo Wagtail Swordtail is this fish crossed with a Tuxedo Wagtail Platy.
The Red Swordtail is a Cross between the Green Swordtail and the Red Platy, sporting different shades of red and called the Brick-red Swordtail and the Velvet Red Swordtail. There is also the Red Wagtail Swordtail and the Red Tuxedo Wagtail Swordtail.
A Variegated Swordtail is a mixture of colors with no set pattern.
The Hybrid Swordtail, is the same fish as the Salt-and-Pepper Platy. No two fish are alike but contain bits of black, red, yellow, and green blotches. If they retain the "sword" then they are called a Hybrid Swordtail rather than Salt-and-Pepper Platy.
Size of fish - inches: 4.5 inches (11.43 cm) - The females get up to 4.5 inches (12 cm), males are somewhat smaller at 4.0 inches (10 cm).
Fish Keeping Difficulty
Aquarium Hardiness: Very Hardy
Aquarist Experience Level: Beginner
Foods and Feeding
Since they are omnivorous the Swordtail will generally eat all kinds of live, fresh, and flake foods. To keep a good balance give them a high quality flake food everyday. Feed brine shrimp (either live or frozen) or blood worms as a treat.
Diet Type: Omnivore - This fish is an ominvore, however it appreciates a higher vegetable component in its diet. Supplementing processed foods with blanched lettuce is an excellent way to facilitate this need.
Flake Food: Yes
Tablet Pellet: Yes
Live foods (fishes, shrimps, worms): Some of Diet
Vegetable Food: Some of Diet
Meaty Food: Some of Diet
Feeding Frequency: Several feedings per day
Water Changes: Monthly
Minimum Tank Size: 15 gal (57 L) - Fifteen gallons could house a single individual with some company although this fish would be much happier in at least a 20 gallon tank with a few of its own kind. Generally it is best to keep a single male with a small harem of females unless the tank is large enough to house a more evenly mixed group.
Substrate Type: Any
Lighting Needs: Moderate - normal lighting
Temperature: 68.0 to 82.0° F (20.0 to 27.8° C)
Range ph: 7.0-8.3
Hardness Range: 12 - 30 dGH
Brackish: No - This is not a brackish fish, however it does seem to appreciate this addition of a little salt in the water. Around 1-1.25 teaspons of aquarium salt should suffice. Removed water should be replaced with salted water, however if the aquarist is topping off due to evaporation freshwater should be used.
Water Movement: Moderate
Water Region: Middle
They are generally considered a good community fish although they will sometimes eat their own (and other fishes) fry. Occasionally a Swordtail can become a bully, especially older males.
Temperament: Peaceful - The males develop a distinct hierarchy. This fish, particuarly of the male gender, may become more bellicose with age. This fish can have quite extensive fins which are often too tempting for fin nippers to resist so avoid combining these fish with them altogether.
Same species - conspecifics: Yes
Peaceful fish (): Safe
Semi-Aggressive (): Threat
Shrimps, Crabs, Snails: Safe - not aggressive
Sex: Sexual differences
Only the male has the "sword" extension on the bottom of the tail fin. The male is also slimmer and has a "sword" shaped anal fin called a gonopodium. The female has a fan shaped anal fin, is rounder of body, and will have a spawning patch at breeding time.
There is an occasional tendency for a male to be slow to develop a "sword" on his tail, especially if a large dominant male is present. When a dominant male becomes old or affected by parasites then this slow developing male may emerge. On occasion if there is no other male, the female may even attempt courtship with another female, though they are infertile.
amalsyikin - 2014-11-22 I've just realized that my swordtail was having the babies when she's dead. I took her body out from the tank and saw her babies were still inside the womb(didn't noticed alive or not). I buried them at my backyard :(.. My question : 1) what may caused the dead? The mother is stressed because of giving birth? Or else? 2) should i took out the babies out of the womb? thank you (who replied me the answers :) )
arriyah - 2014-11-22 you should have took the babies out of the womb
Connor - 2014-10-15 I have one male red swordtail and he is a gorgeous fish and gets on with my red finned platies, mollies, clown loaches, penguin tetras and my neon tetras. But does anyone know when my female red tail platy will give birth because she has been pregnant for ages and has had no babies?
Clarice Brough - 2014-10-17 The average gestation period of a live bearer is about 28 days, so if its been longer than that she may not be pregnant.
Connor - 2014-10-19 Thank you very much for your help and during the time we have had we have had 5 babies and we think it is her because she has got a lot thinner.
Trevor - 2014-09-15 Swordtails do not change sex, the situation you are referencing is a late developing male which occurs when there is already large male in the tank. Other males will develop slower until they reach a size that can compete with the tanks dominant male and will then develop their male characteristics. I have researched it and seen t twice in my own tanks, after which the late developing male would go on to father many fry of his own. This I am sure of from pairing the new males with young virgin females to be sure the changing of sex did not occur.
Clarice Brough - 2014-09-15 You're absolutely correct Trevor. Thanks so much for bringing this to our attention, we will adjust the information right away.
