Xiphophorus helleri
Swordtail
breeding notes

BREEDING: A very easy livebearer that gives birth to large fry. Females can be seperated (breeding trap) when heavily pregnant to avoid unwanted male attention, and to avoid predation of the newly born fry. Even when bred in a well-stocked community tank, some fry will survive. Swordtails will interbreed with platies (Xiphophorus maculatus) if kept in the same aquarium.

Disposition: Somewhat aggresive on occasions Community tank?: Yes, a good community fish
Spawning Method: Adult fish removed from tankBreeding problems: none
Sex ratio: Almost all femalesBreeding difficulty: Very easy
Sucess: Very sucessfulYears Experience: 2
Other Comments: Have had a ratio of 85% female to 15% male. Fed on high protein pellets, black worms and vegetable flakes. unfortunately if female isn't penned and removed after birth she will eat majority of the fry. My spawning method is 1 male per 4 females. None of my males are kept together due to high aggression. Male is kept with females for only 1 month
