Breeding Swordtails

I have a pair of swordtails. I have had them for two months. They are breeding great. The first time they had young I did not get the female in the net breeder in time. She gave birth again two days ago. I did have her in the net breeder this time. I was able to get about 40 fry transfered to my breeder tank this time.
Swords will have young about every 28 days depending on temperature and other water conditions. It is hard to see the gravid spot, but you will notice that she is more "plump" then normal. I will try to get the female in a net breeder about a week before she is due. If you know when she had her last bunch just add 28 days onto this to get the next due date.
They will have the young early morning, right after you turn on the light. Try to get the young out ASAP because she will eat what she can. Keep in mind also there will be still born fry. Do not worry this is normal.
I have my swords in water that has a PH of 6.5 and a temperature of 84. I know this sounds extreme but they are in with discus.
Most females will have about 30-50 healthy fry. This can very depending on the size of the female. Some large females could have over 100 young!!
Good quality Swordtails are getting hard to find. I hope this will help anyone who is thinking about raising swordtails.

Congratulations. Now you'll have to figure out what to do with all of the fry. Good reason to get another tank. lol

I am currently raising a single sword in a ten gallon... I really want him to grow up already! (I know he's not going to grow over night) How old are they before you can sex them? Sorry I've been trying to find this information on the web but apparently no one has pictures of the fry growing up or storys. He's probably two weeks old. Maybe a little older. He's definitely grown. I'm only feeding once a day though... I'm using the liquid fry drops because the finely ground fish flakes go unnoticed. And because I have a super crappy filter I don't want to have to much waste left in the water.. I'm currently cycling a good filter for that tank though. I just want to know if I have a girl or a boy already. If it's a boy I'm going to have to re home him ( I don't want him and his mom doing the nasty) But if it's a girl I am more then happy to keep her. I'm very happy though. This is the first time I might have a good chance at raising the fry. Before I had a batch of 7 or so but I had them in a very over stocked not fully cycled tank (newbie mistake ) I got them pretty big but they died over night from bad water conditions. I hope now that this one has a whole ten gallon to itself I'll be able to raise him to adulthood. I only ever found one fry though... I didn't even noticed one of my females was about to give birth. So I'm assuming the others were eaten ( If it grows up completely I think I'll name he/she nemo.. It seems appropriate) . Any advice is greatly appreciated! :) Thanks!

And just before you laid dead weight upon its shores, I stung you in the face for that's the nature of my core.
