CATDOLL : CATDOLL: Guppy fish has black spots on its body

1. Black spots on the body of guppy

The peacock is about to change color, which is a normal phenomenon in the growth process. Slowly the peacock will become more and more beautiful.

2. The guppies I raise are only a few days old, and tiny black spots have appeared on their bodies. Is that okay?

Personally, I think it’s a problem with the color of the fish itself. Watch the fish swimming, stabilize the water temperature, and feed it, and it will slowly grow.

Welcome to communicate more.

3. Our three guppies were restless all night. One of the fish had small black spots scattered on the upper part of its body, and another fish had black spots near its tail. What happened?

Do you have a big belly? If so, you are pregnant.

4. My guppy has black spots on its tail. How long will it take for it to give birth? I am looking forward to it!

Guppies are ovoviviparous fish. They have strong reproductive capacity and mature sexually early. Guppies have always been considered to be a species of fish with strong vitality, but their life span is quite short, only about one year on average. However, some improved varieties can live for more than one year. It can be said that the life of a guppy is a beautiful but short life. The fact that you only have two guppies left is related to the fact that you went out for a few days without feeding them. It is likely that they were eaten by the parent fish. Here is an article recommended to you. If you have a longer time, you can find something useful to read.

There is no space limit for raising guppies. They can be raised in large tanks or small fish tanks. The first priority for raising guppies is to choose the appropriate equipment and buy healthy guppies. How to buy healthy guppies is very important. You should actually go to the store and carefully observe whether the fish in the fish box are healthy? Are they swimming freely? Is the fish body thick? Are the dorsal fin and tail fin fully expanded? The health of the fish you buy home is a key to whether you can enjoy the fun of raising fish in the future.

Feeding equipment

All you need is a 30-60cm long water tank, filter, bottom sand, insulator, fluorescent lamp and other basic equipment. The most commonly used filter for raising guppies is a sponge filter, because it can effectively filter the bottom sand. It is recommended that beginners choose equipment with strong filtering effect and can maintain clean water quality. Guppies like to filter complete water. Before the breeding equipment is assembled, if the water temperature has been adjusted and the water quality has been neutralized, go buy fish after everything is ready. And initially, you may consider buying 2-4 more water tanks at the same time, because healthy fish will gradually give birth to small fish, and soon the number of fish will increase, and 1 water tank will not be enough.

Water quality stabilization method

People who raise guppies like to use "water stabilizers" because they are convenient to use with tap water. The new water used for water changes must be a mixture of tap water and boiled water, and must be adjusted to have no temperature difference with the water in the original breeding tank. For a 30-36cm tank, try to replace as much water as possible; for a 60cm tank, only 1/2 of the water in the tank needs to be replaced to achieve the effect of changing water. Many guppy owners use nitrifying bacteria in BICOM and DDC when changing water, while some do not use them at all. However, it is also a good idea to develop the habit of using such products when you start raising fish. In short, whether you use or not use external biochemical products, you should always pay attention to maintaining water quality, which cannot be ignored.

Daily food

Guppies can be fed with brine shrimp and various artificial feeds. Brine shrimp larvae are the favorite of guppies. The most famous brine shrimp production area is the Great Salt Lake in Utah, USA. In recent years, the catch of brine shrimp eggs has decreased and the price has become very high. Therefore, if you just want to raise guppies to appreciate their beauty, there is no need to buy this incredibly expensive feed. If you consider the cost, you might as well buy some dried brine shrimp eggs when buying guppies and hatch them at home to feed them. There are many high-quality artificial feeds on the market, and you can prepare a variety of brands as supplementary feeds. When feeding brine shrimp larvae or artificial feeds, you must pay attention to the control of the amount of feeding. Feeding too much will pollute the water quality. In order to do a good job of regular management, the feed must also be used in a quantitative manner.

Daily Management

If you want guppies to grow healthy and beautiful, daily careful management is indispensable. Daily management means cleaning work such as changing water. The number of guppies is also closely related to the frequency of water changes. For example, if you keep 20 fish in a 36cm tank, it is most appropriate to change the water every 7-10 days. Observe the movements of the guppies when feeding them every day to judge whether it is time to change the water. The appetite of guppies in the tank without water change will begin to decrease, and the following obvious symptoms will appear after being placed: the tail fin of the male fish will begin to dissolve or the eyes will be covered with a layer of white film, and the fins will bleed. At this time, the water should be changed immediately. After changing the water, the guppies swim freely and refreshingly. While appreciating them, we will also be infected by their happiness.

Reproduction

One of the attractive factors of guppies is that they are easy to breed. Generally speaking, healthy female fish over 4 months old give birth every 3-4 weeks. As long as the tank is more than 45cm, the probability of adult fish eating fry after giving birth in wild fish will decrease, but the more adult fish there are in the tank, the higher the risk of fry being eaten. Aquariums sell special fry collectors on the market, which can be used to put the pregnant female fish into the fry collector to wait for the birth. The time the female fish is placed in the fry collector should be as short as possible, so it is important to correctly judge when the female fish is about to give birth. When the female fish is pregnant, the black part of the body and the bulging abdomen will feel like they are about to move 1-2 days before giving birth. At the same time, it is also important to pay attention to the fry collector to keep space for the fry to swim freely to the water surface. If this point is ignored, it is easy for the fry to not reach the water surface, resulting in the inability to swim normally when they grow up. In addition, you can also plant some water celery in a 30cm tank and let the water celery float on the water surface to form a natural floating fry collector.

Breeding and selection of fry

The most important thing to raise guppy fry is to feed them enough brine shrimp larvae. Newly born fry should be fed at least twice a day until they can swim freely. It is also very important to select and eliminate deformed fry and fry that do not show characteristics. It seems a bit cruel, but in order to continue the perfect individuals and to appreciate the beauty of the same species of fish swimming in groups, there is no other way except to do a careful and thorough screening. Of course, if you do not want to do the screening and want to keep all the fry and raise them, no one will prohibit it. How to select a good strain? In various specialized books on raising guppies, everyone is taught to pick out fry that do not meet the characteristics of the species as soon as possible and deal with them. Move one male fish and two female fish with obvious characteristics that you like to a new tank and raise them carefully. No matter what method you use, only by not compromising and carefully selecting can you have a chance to raise beautiful guppies.

Disease treatment

After guppies were introduced from Singapore in 1993, everyone knew what fish diseases deeply affected guppies. From then on, the saying "guppies are easy to keep" had to be elaborated into "healthy guppies are easy to keep". Tetrahymena corlissi fish disease, like the pathogen of white spot disease, belongs to the ciliate family. It is a fish disease that parasitizes guppies and is fatal. Fish are prone to this disease if they are too tired, too weak or underdeveloped. The cause of the disease is usually a sharp change in water quality, overcrowding of fish, etc. Once infected, it is not only difficult to cure, but its high infectiousness also makes guppy lovers daunt. The treatment method is usually to take a medicinal water bath for at least 1 month, and adjust the pH value and water temperature of the water appropriately. Formalin bath is recognized as the best bathing method. As for what is the specific medicine, it is still unknown. In fact, if you buy infected sick fish, the cure rate is very small. Moreover, the disease will be passed on to future generations of fish, making it difficult to completely eradicate the root cause of the disease.
