Males develop the classic swordtail extension on the lower caudal fin, while females are usually larger-bodied and lack the sword. This active, hardy freshwater fish is best suited to peaceful hard-water community aquariums with stable water quality, open swimming space and calm tank mates.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003eKohaku Wag Swordtail, Kohaku Swordtail, Koi Wag Swordtail, Koi Swordtail, Wag Swordtail, Swordtail.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eScientific Name (Latin):\u003c\/strong\u003e\u003cbr\u003eXiphophorus hellerii\u003cbr\u003eOften written in the trade as Xiphophorus helleri.

Males use the sword-shaped tail extension during courtship and rivalry. Females give birth to free-swimming fry rather than laying eggs, and breeding can be frequent if both sexes are kept together.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAquarium Category:\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003eCommunity Fish\u003c\/span\u003e\u003cbr\u003eSuitable with peaceful hard-water community fish such as platies, mollies, larger guppies, peaceful rainbowfish, hardy tetras that tolerate alkaline water, bristlenose plecos, snails and Corydoras kept within suitable conditions.

Provide plants, open swimming room and a secure lid, as swordtails are active and can jump. If keeping mixed sexes, expect fry and plan stocking accordingly, as females can store sperm and produce multiple broods. Kohaku and wag markings vary naturally between individuals, so each fish may show a different balance of red, white and dark fin patterning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuitable for:\u003c\/strong\u003e\u003cbr\u003eBeginner to intermediate fishkeepers\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability:\u003c\/strong\u003e\u003cbr\u003eOccasional in trade \/ Captive-bred colour form\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAll images are a visual representation of the fish you will receive, made to be as accurate as possible.
