What kind of fish is a red tropical fish with black spots on its body and black spots on its body?

In general, the reasons for dark spots in fish are as follows:

Fish will appear dark spots when frightened, and they will disappear after a while.

If the water quality is not good or the water quality is not suitable, the water should be changed when the water quality is not good, and the water should be changed immediately if the water quality is not suitable, and the water quality should be adjusted.

Rotariasis (melanosis). The symptoms of this disease are:

The body of the sick fish is thin and dull, and when the lesion is in the gills, it causes breathing difficulties and floats on the surface of the water. Caused by the parasite of the wheel worm in the ** or gill region, the water temperature is above 25 May and August is the epidemic period. If it is black body disease, it is recommended to use 1 salt water for feeding; 20 parts per million potassium permanganate solution dip 10-20 min;

Weakened constitution due to low water temperature. In addition to the darkening of the color on the body, the main manifestation is that he also sinks in the bottom corner of the water and does not like to move. The solution is to gradually increase the temperature of the water. If the temperature is suddenly increased in a short period of time, it may also cause the fish to die due to metabolic disorders.

There are also some fish that will also have dark spots during the discoloration period, and will appear dark spots due to factors such as environmental growth, light, etc.

Is the red tropical fish you have moonshine or redwing?

There are some species of moonshine fish that have dark spots on their bodies, which is normal.

If you're sure it's a disease, could it be melanoma? I've never seen it.,The introduction on the Internet also says that parasites are caused or something.,There's also a ** method.,Check it out.。 But it seems unlikely to be the disease.

Freshwater fish with red spots on their bodies are crucian carp.

Crucian carp is a very common freshwater fish and has a delicious taste, so many people prefer to eat crucian carp. The reason why crucian carp has red spots on its body is mainly related to parasites, water pollution, and the growth environment.

Many fishing friends like to fish for crucian carp, and often post all kinds of large carp in the circle of friends. Influenced by this, it seems that everyone thinks that as long as it is golden yellow, it is a crucian carp. I want to tell you that this understanding is wrong!

The biggest difference between crucian carp and other crucian carp is the form, not the color.

Because the water in which the fish live contains different minerals, even the crucian carp may not be golden yellow, and many of the crucian carp in the wild river are white or cyan. Let's teach you to recognize crucian carp. The yellow-orange-orange crucian carp is the soil crucian carp?

Not necessarily! A crucian carp like this is a crucian carp.

Why do people like crucian carp? Old anglers must know it, because there are very few that specialize in breeding crucian carp. The reason is very simple, the growth of the crucian carp is relatively slow, in the wild environment, the crucian carp can generally only grow to more than 1 tael a year, and the growth is even slower after half a catty.

The crucian carp is slender, small, and has a small mouth, mostly golden yellow (different water quality).

There are only 28 lateral lines on the side line of the fish, and there are only 28 scales from the side line, and the scales are small. The back of the crucian carp is blue-black or yellow, the belly is white, the tail fin is thin and the color is lighter than the body color, the flesh is light red after cooking, the lip is very thin, and there is little or no meat on the gill shell; The head is round and small, and the transition between the head and the body is very smooth, so there is no protrusion of the body.

However, even in the wild river, the number of pure soil crucian carp is actually not much. It is mainly the farmed hybrid crucian carp and the release of crucian carp that have created new hybridizations. The number of crucian carp that leads to pure qualifications is decreasing.

In terms of weight, the crucian carp rarely exceeds one and a half catties, and it takes at least 8 to 10 years for the crucian carp to grow to 1 catty, and even if it grows to about two, it will take years.

This is a fish with black spot disease, the pathogen is mainly water mold and mold, parasitic on the wounds and eggs of the fish body, is a more common fish disease. **Mainly the fish body is injured, the scales fall off, etc., resulting in the invasion of germs into the wound.

**Method: a. Splash 250 grams of salt and 250 grams of baking soda mixture on a 100cmx55cmx45cm fish tank, insist on several times, and the effect is remarkable.

b. Dissolve malachite green grams or methylene blue in 100 kg of water, soak the fish body for 10 20 minutes, and the mycelium can be seen to fall off after a few days.

c. Soak in 2%-3% salt water, once a day, for 5-10 minutes each time.

d. Mix 2 parts per million (2ppm) potassium permanganate plus 1% brine and soak the diseased fish for 20-30 minutes.

e. Increase the water temperature to inhibit the growth of water mold. And a 15-watt ultraviolet lamp can be used to irradiate for several hours a day, which can effectively inhibit and eliminate water mold.

Fish are injured by friction, and the fish body is injured by trauma or parasites that cause the fish's ** to be infected by mold spores after being injured, thus inducing black spot disease.

Reason 1: Or you can dissolve malachite green grams or methylene blue in 100 kg of water, and soak the fish body for 10-20 minutes; Or soak the goldfish body in 2%-3% salt water once a day for 5-10 minutes each time.

Reason 2: In daily life, it is necessary to do a good job of preventing black spot disease, such as being careful when fishing and transporting, so as not to let the goldfish be injured and avoid it being infected by parasites and germs.

Fish with black spots are called pike.

The pike (scientific name: esox reicherti) is a pike family. Pike is a fish, and this species is a special fish in the waters of the high-latitude Hantong round caravan cold area.

Generally, the body length is about 600 mm, the vertical weight of the body cavity is 1000-2000 grams, and the largest individual can weigh more than 16 kg. The body is elongated, the front of the head is flattened, and the snout resembles a duck's beak. The mouth is large, and the teeth of the premaxilla, mandible, vomer, hip and tongue are sharp.

The scales are small. The lateral line is not obvious. The dorsal fin is shifted backward, opposite the anal fin.

The body is bronze on the back, white on the abdomen, and has black spots on the sides.

However, there are often new changes due to different habitats. It is distributed in the river, Timi River, Polonai River, Bear Lake, Erguna River, Shilka River, Onen River, and Ingoda River, Nenjiang River, Heilongjiang River, Songhua River, Ussuri River, Dalai Lake, Jingpo Lake, Wudalianchi, Suifen River, etc. The type origin of this species is in the Onen River and the Ingoda River.
