Breeding Tropical Fish For Beginners - Guppies & Swordtails
Michael Magnum


Breeding tropical fish can be a lot of fun. Try your luck at
breeding livebearers such as guppies or swordtails.

Equipment Needed:
Breeder Box or Breeder Net
Breeding Grass
5 or 10 gallon tank for the baby fish or a tank divider that you
can use for your main tank.
A pair - 1 female and 1 male

Two of the more popular tropical fish for beginners has to be
Guppies and Swordtails. Guppies and Swordtails are livebearers
which means that their babies come out swimming. Like most
livebearers, there is not much to getting your guppies or
swordtails to breed. If you have a male and a female then you
will eventually have a pregnant female. The gestation period for
livebearers is usually 28 days but can range from 20 to 40 days.

Place the male and female in the same tank together and they will
soon mate. You are probably asking, how can I tell when the
female is pregnant? When a female guppy is pregnant she will
develop a dark triangular shaped gravid spot near her anal vent.
This will get larger and darker as the pregnancy progresses.
While you are waiting on the female to develop the babies it's
time to make sure you are prepared for the delivery. We use
plastic breeder boxes and always have without any problems. A
breeder box is a small box plastic box about 4 inches long by 3
inches wide and 4 inches deep. There is a removable "V" shaped
trap in it which serves to separate the mother from the babies.


When the mother fish has babies they fall through the slot in the
"V" into the bottom of the box. After the mother is finished
having babies, you can remove the "V" trap and the mother so that
they babies have more room to grow. Some people have had bad
experiences with breeder boxes and now only use a breeder net. It
is also a good idea to purchase some real or plastic breeding
grass for the top of the aquarium. The breeding grass is just in
case the mother gives birth before you have a chance to put her
in the breeder box. The young babies instinctively will swim to
the top of the aquarium and the breeder grass provides a great
hiding place so they won't get eaten by the bigger fish in your
tank.

To feed your new arrivals you can use finely crushed flake food.
Using your fingers, you can rub the flakes into a fine powder.
Some only feed live foods such as baby brine shrimp. Live foods
would definitely be the best way to go, but for most this is
simply not feasible. Crushed or powdered flake food will suffice.
Try to feed the babies 3 very small meals per day. You will
invariably feed too much and the excess food will drop to the
bottom of the tank or breeder box. To clean a breeder box we like
to take a 3 ft. length of aquarium tubing and a small bucket. Use
the tubing as a siphon to clean the bottom of the breeder box. Be
careful not to siphon any baby fish.


Try to perform 25% water changes weekly for your baby guppies.
This will aid in the optimal growth of your baby tropical fish.
After a few weeks in the breeder box your new babies will soon
outgrow their home and you will need to move them either to a new
tank or your main tank with a divider installed. By 8 weeks old
your baby fish will most likely be able to return to the main
tank without a divider.
