Guppy Breeding

A detailed account of how I breed my guppies

by fballguy

For breeding guppies, a minimum tank of 10 gallons is reccommeded. ALWAYS make sure the tank is cycled before introducing fish.(A page on fishless cycling soon.) In a 10 gallon tank, it is reccommended to start with 3 guppies, 1 male and 2 females. For a 20 gallon tank, you can do 2 males and 4 females, and so on... For our purposes we will be going over how to breed guppies in a 10 gallon tank.

Always remember... keep 1 male to every 2 famales. This is very important, as male guppies are randy little fish, and will constantly harass any female around. If you keep too few females, the male may harrass her to the piont of death. If you have at least 2 females to every male, it gives the male more than 1 girl to chase, so at least 1 girl is always getting some rest.

The tank cycling period can take a long time. You can use this time to decorate your tank. Live or fake plants will do just fine. There is a plastic breeding grass that works well for giving fry places to hide. The more plants you use, the better. I prefer live plants myself. Java moss is great for giving fry places to hide. It is also a very versatile plant. You can float it by tying it to a cork... You can tie it to driftwood or other decor... You could stick it to the substrate... Or you can just let it float around and do it's own thing. Wisteria is another plant I reccommend. It is a stem plant that you can jam into the substrate and it will grow like mad. You will also need some sort of floating plant. Guppy fry will spend most of their time near the surface, so a floating plant is critical to their survival. My favorites are anacharis and hornwort. Use a suction cup to get it to stay in one place. There are many other plants that work great. I just reccommended these because they are very easy to care for, and need little to no maintenance, other than the occasional trimming.

So, once your tank is cycled, is it now time to choose your fish. Remember to get 1 male for every 2 females you get. (If you coulcn't guess by now, this is very important.) What color morph of guppy you get is your choice. Just make sure you get guppies that are healthy; no signs of ich, fin rot ect. If they have white spots growing all over them, any kind of fungus, or if the fins look a little bit beat up do not get them. Go to another fish store or wait and come back the next week.

Now that you have your fish, it is now time to introduce them to your tank. Make sure you acclimate them correctly.(An acclimation page is coming soon.) Once you release them into the tank, they will probably go after each other looking to mate right away. But do not be worried if they don't right away, they will very soon.

To get the most fry, be sure to feed high quality food. Frozen bloodworms and live blackworms are greedily accepted, and will make the female guppies produce loads of fry.

In about 30 days it will be time for the guppies to go into labor. It will take anywhere between a few hours to maybe a day or 2. It all depends on how many fry are born, and how stressed the mother is. It may be a good idea to remove the male during labor, and give the females a little bit of peace. You also may want to turn off the lights to help decrease stress.

Once the fry are born, you have a decision to make. You can either choose to remove the fry to a different tank(cycled of course) or you can leave them in the same tank as the parents. The parents will eat the fry if you decide to leave them, so that is why the plants and hiding places are so important. However you will lose some fry, but don't worry, you will have more in another month!

Young fry will release hormones into the water that slows growth. It is very important in the first 1-2 months to change 25% of the water every 2-3 days. This removes the hormones and allows the fry to grow at a quick pace. For the first month, liquid fry food is best, but if you grind up flakes to a powder that will be sufficient. Once the guppies grow to about 1 inch long, you can begin to feed as you would if they were adults.

Good luck and happy breeding!
