Some guppy breeders and enthusiasts might argue that you don’t need to follow that ratio, but the more fish you have in your tank, the more often you will have to clean it and change the water. Consider this when deciding what size tank to get, and how many guppies to keep in it.
You can buy these supplies at a local pet supply store for a relatively low cost. You will also want to buy a chlorine testing kit, just to make sure the water is completely free of chlorine before adding your fish. Follow instructions on the dechlorination bottle. Nearly all tap water has a certain level of chlorine in it. You can use purified, filtered, or distilled water that is free of chlorine, to begin with, but to be safe, still test the water for chlorine before putting your fish in it.

If you need a heater, make sure you buy one that is appropriate for the size of the aquarium you have. For example, if you have a 5-gallon tank, you’ll need a less powerful heater than if you have a 20-gallon tank. Ask the associate at the pet supply store if you aren’t sure which heater you need. To avoid overheating your tank, it’s best to keep it out of direct sunlight. Use a heater if you need to raise the temperature, and use an artificial light in the tank rather than sunlight. If for some reason the water becomes overheated, take some of the warm water out and replace it with cooler water to lower the temperature slowly.
Even if your tank did come with a filter, you can always change it out for a different or better one should you feel you need to. Make sure your filtration system can keep up with the amount of fish you have and the size of your tank. A regular filtration system should be enough to keep your tank oxygenated, but you can also add an airstone to help add oxygen to the water if you have a larger tank or if you have lots of fish. You should keep the tank set up and working for a month without any fish, just avoid the temptation of buying any fish before. The bacteria are in the media part of the filter (where bacteria develop) and clean out the toxic substances that are dissolved in our water, as fish contaminate their own water by excreting. These substances aren’t removed by the mechanical system of the filter, only bacteria can transform these highly toxic substances into others much less toxic, that can be removed by changing part of the water weekly. In this month feed the bacteria with some fish food (1 flake each three days), in order to train them for when the fish come. This whole process is called cycling.
Make sure you rinse all substrate and decorations before placing them in the water. You want to make sure you get all the dust or dirt off of them that they may have picked up in the supply store. Avoid adding things taken from nature, such as clams, roots, sand, because they might contain parasites or will modify your pH (or the general hardness if adding calcareous stones) This may lead to illnesses in your fish or even their death. It’s better if you buy them in your pet store, this way, you avoid unpleasant surprises. Only those who have experience in keeping fish would pick things from nature, as they difference between roots and rocks (making a previous study on them and getting some information in advance) which are innocuous to the water quality and those who are not.
If you are using natural light, like placing your tank near a window or light source, make sure it doesn’t affect the temperature of the water too much. Make sure your water maintains the proper temperature for your guppies. Doing this might lead to algae problems, so it’s better to put artificial light.
Brine shrimp, earthworm flakes, dried bloodworm, white worms, and mosquito larvae are all great options for feeding your guppies. Flake food with fish meal as a primary ingredient is a great choice. Read the labels before buying your guppy food.
Be careful not to overfeed your guppies. They should be able to consume the food you give them within two minutes.
If your tank goes cloudy, lighten up your feeding by about 20% for a few days and see if that helps the fish readjust and the water to balance itself out again. If this happens it might be due to a peak of toxic substances (ammonia and nitrite) because of skipping the cycling period. . .
If you want to avoid breeding, you will want to keep all one gender in your tank. Guppies give birth to live fry rather than laying eggs, so if your guppies breed, you will see their babies right as they are born. Learn more about breeding guppies before doing so.
When cleaning, you won’t want to take out all of the water and replace it. By taking out only 25-40% of the water, the fish will be better able to adjust. [9] X Research source Your filter should be doing most of the heavy lifting on a daily basis, but using a siphon hose (easily purchased at a pet supply store) to clean any algae or food from the bottom of the tank will help keep the tank cleaner, and your fish healthier. Clean the glass on the inside of the tank if you notice it’s getting dirty. Use a razor blade to scrape off any grime that might be on the inside of the tank, then use the siphon hose to suck it up. Also, you may want to periodically remove any decorations from the tank and rinse them thoroughly to remove any algae or grime build-up.
Keep your tank clean and well-maintained, and you will likely not have any issues with sickness or disease. If any guppies die, make sure you remove them quickly from the tank. If any guppies do show signs of disease or sickness, quarantine them in a separate tank while they heal so they don’t infect the others. Some people recommend that you add a bit of aquarium salt to the water to prevent fungus. If you add any tank mates, make sure they can tolerate this (for example, corydoras cannot). Marine salt and cooking salt are not the same things.
