Blub
Swordtail
(Xiphophorus hellerii)
Common names: Swordtail,
Size: 13cm (approx 5 in)
pH: 7.0-8.0
Tempº: 22ºC - 28ºC (71 F - 82 F)
Tank region: Middle-Top layer
Origin: Mexico, Belize, Hondorus.
Gender: Males have swords on their tails. The males analfin is long and tube shaped (called a gonopodium), the female’s is triangular.
Notes: Swordtails are an old favorite - boating all the good points of the livebearer family in a larger package.
Hardy, pretty, active, easy to breed and lots of colour varieties to collect. This fish is a perfect addition to a community aquarium if you want a larger fish. Watch out though, these fish WILL breed if you have males and females, and whilst some fry are eaten, 1 or 2 from every batch make it to adulthood. It is also a bad idea to keep male Swordtails with Female platys, or vice versa. Both species are in the Xiphophorus genus and will interbreed readily.
