Swordtail Tips

Swordtail

From: DVO
I currently have 2 female and 1 male swordtail that are actively breeding. A lot don't make it, they get eaten as they're born, but we have had some success in a 20 gallon tank. We're breeding what looks to be marigold/velvet hi-fin females and the male is yellow and orange with a long, beautiful red tail. Some babies come out clear, some yellow, some orange and even some with dark brownish spots on their heads.

When my female green swordtail is about to give birth, I put her in the breeding net, along with some small plastic plants. If I'm around when the babies come, I watch and wait until she's about done, then drain about 2 or 3 gallons of water from the main tank into my 5 gallon fry tank. Then I take about a 4 foot length of air tubing and siphon the babies from the main tank to the fry tank. Once the mother is done birthing, I top off the fry tank with water from the main tank and leave the mother in the breeding net for a day or two so that she can recover her strength before being put in with the other fish again. The plastic plants offer some protection for the babies if I'm not around or awake when the big moment comes, because the mother will often start to eat the babies soon after giving birth.

I have swordtails and I saw one having babies in our 55 gallon tank. I moved her to the net in our 10 gallon tank. She had about 40 fry. How can I tell when my swordtails are close to giving birth.
You really just have to watch them closely, watch for swelling in the stomach region and make a note of when they last gave birth and then make an educated guess knowing that their gestational period is usually around 4 weeks. If this is the first fish birth for you, you'll just have to watch them closely. Look for them to become less active and maybe less hungry right around the time they are ready to release the fry. When it happens, write the date down and you'll have a better idea for when it will happen again. Time to get more tanks!
