How do swordtails breed??

Recommended Posts

they are live bearers so the male impregnates the female and she gives birth rather then them laying eggs. add some elodea or foxtail or other floating plant mass for the fry to hide in as they grow. the adult fish can in some instances eat the fry as they are born hence the need for plant mass. HTH ;)

Hey I got a trio of sword tails for free and wanted to know how they breed etc if there are any tip from ppl post thanks :)

prolifically!

they have batches of sometimes over 200 live babys.

females capable of multible batches about a month apart from a single mating (superfetation)

Male has the sword the female does not. They are easy to breed. Swordtails are known to change sex too so you could go from a trio to a reverse trio.

Has the changing sex thing been proven?

I always just assumed menapausal girls just took on male characteristics, but such blockheads were infertile?

then again I have not really kept pace with the livebearer world that closely besides raising my own batch of 1!

Donny you should google it with the changing sex. Apparently your search should bring up 40% yes, 40% no and 20% has both genders. Had a tank of them recently and seemed that the female population was growing and the male was dwindling and remembered back 35 odd years ago there were these blue encyclopedia's and it was either world encyclopedia or animal encyclopedia and there was something there about 75% of them could change sex but only 23% could actually change back and figured what happened recently was just down to what I read many many years ago. I know the boys are more jumpers maybe it was just a slow exodus.

Livebearers are interesting fish. If you have a female sword who has been near a male, she is pregnant. The sperm can be stored within the body. You will see the female belly expand and almost look squared off when readdy to give birth. If you are seeing a girl get fat and then thin, she has given birth.

Normally the female when due to give birth will go and find a very quiet location. Of course any fry is perfect snack size. Once the female gives birth she kinda goes into a hypnotic state that gives the baby a chance to get away from her hungry mother. While that works well for the mother if the others are present and hungry......

If you are seeing the fat and thin stage you may need to set up a seperate tank. You can get various breeding traps, but they do not work well especially for the size of swords. Mother will tend to stress and hold on to her babies and not drop them.

ps ~ I still remember being told male swordtails had the long tail so they could jump from puddle to puddle with it! Something that persisted in aquarium lore for many decades after being shot down by the great Gunther!
