What water temperature is suitable for guppies? Keep temperature control in mind when keeping them
Guppies - just from the name we can tell that their tails look a bit like a peacock spreading its feathers, very beautiful, with particularly high ornamental value. Guppies are a kind of fish with particularly high ornamental value, very suitable for keeping at home. Tell you about keeping guppies ⟦4 <p>Guppies - just from the name we can tell that their tails look a bit like a peacock spreading its feathers, very beautiful, with particularly high ornamental value. Guppies are a kind of fish with particularly high ornamental value, very suitable for keeping at home.</p><p></p><p><strong>Tell you the water temperature to watch out for when keeping guppies</strong></p><p>1. Suitable temperature </p><p>Guppies are highly adaptable and can survive within a temperature range of 16-34°C; their most suitable growth temperature is 22-30°C, with a pH of 7.2-7.4 in slightly alkaline water. As for guppies, some people believe they can tolerate a minimum water temperature of 15°C, while others believe the lowest temperature guppies can tolerate is 16°C. Relevant experts once conducted experiments on this, and found that at a water temperature of 16°C, guppies still swim freely. However, at water temperatures of 14-12°C, guppies begin to respond slowly, gradually lose balance, and may even die. So, in a home-keeping environment, when the water temperature is below 14°C, a heater or heating rod should be used. </p><p>2. Breeding temperature </p><p>When guppies breed, a larger aquarium should be chosen, with the water temperature kept at 26°C, and more aquatic plants should be planted, then brood fish are added at a ratio of 1 male to 4 females. When the female is pregnant, and the gravid spot becomes large and black and the anal vent protrudes, she can be netted into another aquarium to await birth. The temperature in the birthing tank should be 1-2°C higher than the original water temperature, with moss or aquatic plants placed at the bottom of the tank to give the fry a place to hide. After the female gives birth, she should be netted out immediately to avoid eating the fry; or a funnel-shaped isolation wall can be made with a plastic sheet, immersed in the water, and the birthing female placed in the funnel, so that after the fry are born they fall through the hole at the bottom of the funnel into the water outside it, and the female cannot eat the fry.</p><p></p><p><strong>How to keep guppies </strong></p><p>1. Have an appropriate water temperature </p><p>Guppies can accept water temperatures from 18°C to 34°C. If it is below 18°C, some problems are more likely to occur, such as: loss of appetite, lethargy, and susceptibility to diseases such as water mold, so whether to use a heater can be decided according to individual circumstances. </p><p>2. Appropriate pH value in the water </p><p>The most suitable pH for guppies is between pH 6.5 and pH 7.5. The acid-base value in the water has a considerable impact on guppies. The acid-base value is in logarithmic form, so pH 5 water is ten times that of pH 6 and one hundred times that of pH 7. Therefore, what is just a small "1" difference to humans may already be near-fatal torment for guppies. </p><p>Another thing to note is that if the keeper changes the water infrequently, over time the water quality will already have turned acidic due to various factors. At this point, if a large water change is suddenly made, it will inevitably cause a considerable shock to the guppies. </p><p>3. Appropriate hardness in the water </p><p>Guppies like slightly hard water, with hardness around 10-15 degrees. Even so, in the moderator's personal opinion, water hardness does not have much impact on guppies. Take two countries with considerable history in keeping guppies: Germany and Japan as examples. Germany's water is hard water, while Japan's water quality is all soft water, and these two completely different conditions can both raise guppies very well. It can be seen that guppies have strong adaptability and relatively do not need the keeper to put effort into adjusting the water hardness level. This is also one of the reasons many people often say guppies are easy to keep.</p><p></p><p><strong>The prospects of keeping guppies </strong></p><p>1. Easy to breed </p><p>The breeding cycle of arowanas is 5-10 years. Although flowerhorns can lay eggs every month, the breeding success rate is pitifully low. Guppies are not so troublesome. With a breeding cycle of about 25-28 days, from fry to adult fish they can breed in only 3-4 months, and each birth can produce 10-100 fry. Such a breeding volume and such a breeding speed can really be considered outstanding among today's popular ornamental fish. Basically, with currently home-kept guppies, fry will be born before long. This kind of ornamental fish that easily overpopulates a tank is deadly for fish keepers who love breeding. </p><p>2. Easy to innovate </p><p>In the ornamental fish world, high breeding efficiency means the possibility of innovation. Breeding once a month, with such a short cycle, is bound to give a shot of excitement to those friends who like breeding, innovating, and cultivating new strains. In just over ten years, guppy varieties have risen from a few hundred to over a thousand. Such a speed completely matches the pace of the current era, and this has also caused the status of guppies to gradually rise. Although these past few years have not been very prosperous, I believe that even so, the prospects for guppies are still very much worth looking forward to. </p><p></p><p>3. Low price </p><p>Everyone knows that many ornamental fish now cost thousands at the drop of a hat, and then tens of thousands, with some top-grade fish selling for more than 100,000. Guppies are different - even top-grade ones rarely cost over a thousand, so such fish are more in line with what the general public can keep, which is also why they have such a broad audience. This is actually just like horses: wealthy people can spend heavily to buy a thousand-li steed; while those with ordinary means, we just buy a hundred-li spotted horse. How many wealthy people are there, after all? In the end, ordinary people are the majority, and guppies belong to a species that both ordinary fish keepers and high-end fish keepers can keep. </p><p>4. Easy to keep in mixed tanks </p><p>Ornamental fish, as the name suggests, are kept by us for viewing. Many friends like to keep many species of fish together, and guppies are gentle in temperament and can be kept together with almost all small fish, and can accept either a planted tank or a bare tank.</p><p></p><p><strong>How to change the water for guppies </strong></p><p>Guppies are one of the common ornamental fish, and many aquarium enthusiasts are very fond of guppies. As the saying goes, to keep fish first keep the water. Without clean, high-quality water, guppies cannot live healthily, and you will have no way to appreciate their beauty and elegance. Keeping guppies requires special attention, and how to acclimate guppies to water is very important. Now, many of the common household water purification products use a combination of several technologies. In fact, the focus of our daily requirements for water treatment technology lies in safely replenishing water. When acclimating guppies to water, special attention should be paid. </p><p>Many people like to use materials such as activated carbon as filter media, because activated carbon can adsorb organic pollutants in the water onto its surface, but it has no adsorption capacity for bacteria, viruses, and alkaline substances in water, so there are still certain shortcomings. Representative products that use activated carbon as filter media include water purifiers, central water purifiers, and so on.</p><p></p><p>We all know that fish cannot grow without water, so guppies are no exception. If guppies are to grow healthily in a fish tank, the requirements for water quality are of course very important, so reasonably mastering guppy water-changing techniques is very helpful for breeding guppies.</p>
