If you’re looking at breeding guppy then they are going to need the right conditions in which to thrive. That involves getting the right tank as the chances of a guppy surviving on their own aren’t high. That’s due to adult guppy fish having no parental instincts and eating their young fry.
If you do it give them an environment in which to thrive then you’ll find that breeding guppy is very easy. They are quite simple to take care of, produce a lot of offspring and also reproduce quite easily. Here we take a look at the type of conditions they need to be in.
At the minimum, guppy should be in a tank that is at least 10 gallons. If you have more than four guppy fish then you are probably going to need a bigger tank than that. Having an overcrowded tank can lead to a wide variety of problems.
For the ideal conditions, you probably want to have a tank that is around 40 gallons. In such a tank you’d be able to keep a wide variety of guppy in a comfortable environment. In a large tank you can also more easily control the level of toxins and filtration.
There are two rules that people can follow in terms of how many guppies you can put in a tank and that is either having a maximum of one guppy per gallon or one gallon for every inch of guppy. The second rule can take into account tanks with a larger female population, as females are usually bigger than their male counterparts.
Of course, guppy fry won’t need quite this level of space but you want them to be able to thrive. If they are in too small a space then their growth can be stunted. Once you have the right tank size then you can focus on getting the right conditions.
To promote the perfect growth of your guppy fry, they need to be placed in perfect conditions. Here we take a look at what you’re going to need.
LED lights are going to be the best option for any tank due to their efficiency but don’t leave the lights on constantly. Guppy fry will need their rest and should be kept in darkness for at least 8 hours per day otherwise they can get stressed.
The best way to do this is with a timer that can automatically control the lights. Such timers are easy and cheap to acquire and you won’t have to worry about manually controlling your lights every day. There are also times when you’ll be away from home and need to keep them in their light schedule.
Guppies don’t need the temperature to be too warm but do need it constantly between 72-79F. You’re most likely going to need a heater to control that as most people can’t trust having the correct temperature all year round.
The best solution is to get a heater where you can preset the temperature. It will then turn off or on as required and takes the guesswork out of it. While guppies are quite easy to keep, they are quite sensitive to sudden changes in temperature. It’s worth noting that you need to double-check you’re getting a heater with enough power to heat the water volume you have.
Almost all aquariums are going to need a filter. As guppy fry are very small, your filter shouldn’t be dangerous to them. It may be that you need to place a mesh or something similar on the inlet to stop them from getting sucked in.
Sponge filters are particularly safe for guppy fry and can, therefore, be the best choice. If you’re choosing another type then caution is required.
We looked before at what the right temperature should be but what about the rest of the water parameters?
pH – Guppy like their water to be neutral in pH and as close to 7 as you can get would be great. If anything, it can be slightly on the alkaline side and anything between 6.8 – 7.8 is fine.
GH – Having slightly harder water isn’t going to be much of an issue. Around 200ppm is a good spot to be at as the minerals in the water can be healthy for a guppy.
Nitrite – This should be as close to zero as possible. If you get high readings then change your water.
Nitrate – Safer than Nitrite, you still don’t want to have a higher reading that 40.
Ammonia – Their feces contain ammonia and it can build up over time and become toxic. You want this reading to be close to zero.
If you wanted to raise guppy fry but don’t have a separate tank in which to do so then you may be tempted to get a breeding box. They can be a perfect choice for anyone wanting to keep the guppy fry safe from the adults.
The only thing to note here really is to not stunt their growth. If you keep them in there for more than a couple of weeks then you could well have problems. Release them into the rest of the population as soon as it’s safe to do so.
As with any fish, you want to be protective of their water. Even though you have a filter, it’s best to change the water to remove the likes of food particles, waste products and to oxygenate the water. This is especially important for fry as they are more affected by toxins. Poor water quality can stunt growth and increase the chance of deformities.
Guppy fry are fairly easy to keep and are great for breeding due to how frequently they breed and the number of babies they have. While that is true, you still want to give them the perfect tank conditions. If you follow the guide here then your guppy fry are going to develop into thriving adults.
