- Water Temperature
- Nitrogen Cycle
- Ambient Place to Mate
Once you have chosen the best pairs or trios among your guppy fish, you may need to set up the tank in a condition favorable for mating. Remember that guppies are tropical freshwater fish, so it is best to have a tropical water temperature. The favorable water temperature for guppy fish breeding would be around 74 to 78 degrees Fahrenheit or 23 to 25 degrees Celsius. If you are leaving in the tropics, you may just leave it on a room temperature.
Nitrogen Cycle
Females will ovulate easily in a pleasant water condition. And what adds on a good water condition are the Nitrogen levels in the water. There are no chemicals that would create a good Nitrogen Cycle available on the market. The Nitrogen Cycle in a tank is produced when Nitrogen becomes a byproduct of ammonia processed by the nitrifying bacteria. The waste products on the tank will be consumed naturally by these nitrifying bacteria hence producing Nitrogen on water which is healthy for your pet fish.
It is best NOT to put mating pairs of guppies in a new tank. You may leave the tank for a week, for it to have a sufficient Nitrogen Cycle. Also having an under gravel filter will let the nitrifying bacteria have a habitat. This would be the place where tank waste products and ammonia be eaten by this nitrifying bacteria which in return releases Nitrogen and promote a good Nitrogen Cycle on your tank.
Ambient Place to Mate
Just like any other creatures, there is always a mating place. In order for the chosen pair to have mutual relationship with each other, they should be separated from the rest of the group. You may only as little as a 5 gallon aquarium for a pair or trio. Most important is to have the tank or the pond to be a darker environment. Do not put lighting on the tank as this will stress the fish.
Once these conditions are met, leave the pair for a few weeks until you see the gravid spot on the females.
