ive just bred swordtails by acccident lol!!!!!!!
had 1 female and 2 males, once the female got pregnant she grew huge, she had the fry and still huge much bigger than my other swordtails! i just have a normal tank, few ornaments few plants and they seem happy enough, although i just purchased another female and 2 more males thought about breeding more, and they seem to attack 1 ov the males, no idea why just they dont like him, bit off all his fins and some scales, ive had to move him!!!!!! but the other 5 r doing fine, and im hopeing to get some more babys 1 day
