Why do tropical fish look beautiful?

Most of the fish have a lighter belly, generally milky white, commonly known as "fish belly white"; The color of the back is relatively strong, such as black, dark gray, grass green or russet. The color of fish with a strong back and a light belly plays a very important role in its life to hide itself and avoid predators. In zoology, this phenomenon is called "protective color".

Fish can also adapt to different environments and have different colors, making their body color similar to their surroundings. In particular, the fish in the tropical seas are even more colorful and dazzling. For example, the peppercorn bream, which lives in seaweed bushes, has blue stripes and green spots on its body.

Some fish near red coral reefs have dark red bodies.

The body of the glass fish moving in the clear water is almost completely transparent, and even the bones and internal organs in the body can be seen. Flounder, which crawls on the sediment of the seabed, has a russet body.

Why do some fish have a particularly bright color, while others change color? This is because the dermis and scales of fish have pigment cells, which include red, orange, yellow, black and other pigments. These pigments can be mixed to form many different colors, giving the body a vivid color, with spots or stripes of different sizes, etc.

In the fish pigment cells, there is also a kind of "silver light" cell called struvin, which is mixed with the pigment cells to produce pigment, which can make the fish's ** sparkle and radiate a dazzling light. At the same time, due to the expansion and shrinkage of pigment cells, the color of the fish changes.

Butterfly fishButterflyfishButterflyfish, belonging to the butterflyfish family, is one of the most colorful saltwater fish except for the humphead fish. They are typical reef fishes, with a side-compressed body shape and a slightly protruding snout. There are many species of butterflyfish, with bright colors and elegant postures, and they are the most important members of marine ornamental fish.

Clownfish. Clownfish is a common name for the subfamily of anemone fish of the damselfish family, because it has one or two white stripes on its face, like a harlequin in Peking Opera, and is a tropical saltwater fish. There are 28 known species, one from the genus Sparrowfish and the rest from the genus Doublesawfish.

Clownfish have an inseparable symbiotic relationship with sea anemones, hence the name anemone fish. The clownfish is particularly cute, and if you have watched "Finding Nemo", you will definitely be familiar with it, this tropical fish is red and white in color, very small in size, and very agile swimming.

Probably because the temperature is suitable, and the resources of various living environments are relatively abundant, and there are many species, so tropical fish products are also very rich.

Since there are many colorful coral reefs and coral trees in the tropical ocean, in order to avoid the enemy, the tropics "dress" themselves up in a colorful way. This way, once an enemy is spotted, they can hide in the coral bushes and blend in with their surroundings, obscuring their vision.

In fact, only male tropical fish are very beautiful, because male tropical fish attract the opposite sex for courtship through their beautiful patterns.

Why tropical fish are beautiful in appearance is a wrong statement. Tropical fish are ugly, ugly, and some are. It's just that you can't see it, because everything you see is beautiful, and even for the sake of beauty, use a laser to make colors, otherwise you will buy it?

Most tropical fish are carnivorous, a few are omnivorous, and a few are herbivorous. Carnivorous fish are further divided into ferocious and mild. Fierce mouth and fierce temperament, like to eat small fish, small shrimp and earthworms and other large pieces of food, such as Texas leopard, Arowana; Fish with a mild temperament have a small body and a small mouth, and like to eat small animals such as daphnia and midges larvae.

The tropics receive more time in the sun. The intensity of the light is also relatively large. It is easy to generate brightly colored body colors. The sunny environment is full of colorful things. As a result, the body color of the fish is also more diverse.

In addition, there are many colorful coral reefs in the tropical ocean. In order to avoid the enemy, the tropical fish dress themselves up in colorful colors, and once the enemy comes, they quickly hide in the coral, so that they are not easy to be detected by the enemy. Bright colors are their best camouflage, which is also the result of evolutionary selection.

1. The influence of temperature and eating habits

The higher water temperatures in the tropics have resulted in many tropical waters in fish containing higher levels of fatty acids and free fatty acids, which can make the meat stale and have a stronger fishy smell. In addition, natural disasters such as heavy rains can lead to water pollution, resulting in the proliferation of microorganisms in the water, which can also adversely affect the taste and meat quality of the fish. In addition, the general preference for sweet and sour flavors and oily eating styles in tropical regions has led to the addition of spices and seasonings during fish farming and processing, which can mask or destroy the original taste and texture of the fish.

2. The influence of the living environment of tropical fish

Many tropical fish inhabit environments such as freshwater lakes, rivers and rainforest waterways with abundant aquatic vegetation. These complex water environments give tropical fish strong immunity to a variety of parasites and external threats. However, the pollution and impact of heavy metal pollution, organic pollution and microplastics on fish meat in these environments cannot be ignored.

In addition, tropical fish grown in the wild also experience many predators and competitors, and their meat is often not tender enough, and there are too many scales and bones that affect the taste.

3. The influence of dietary structure and healthy food concept

Tropical fish is a relatively unpopular ingredient in China, and most people don't know much about it, and they can't find the fun and nutritional value of food from it. In addition, in the context of the increasing emphasis on healthy diets of modern people, people's willingness to consume tropical fish containing high amounts of mercury, vibotocyanide and other harmful substances is also declining.

4. The influence of cultural and religious factors

In many tropical folk religions and ancient cultural traditions, the consumption of certain fish species is often forbidden, which also contributes to the sluggish local market demand for tropical fish. In addition, the evaluation and tasting standards of tropical fish vary from one culture to another. For example, in some cultures, people like to try luxurious giant tropical fish, while in others, people prefer small fish species and may add more seasonings and spices to the processing of the fish.

1. The reason for the colorful color of tropical fish

Tropical fish have a variety of colors on their bodies because they need color to attract the opposite sex to reproduce. Different colors represent different genders and breeds, and at the same time they are one of the ways they communicate. For example, male tropical fish tend to be more vibrant in color than females.

In addition, the colors of tropical fish are also deceptive. They may produce colors that resemble background colors to confuse predators as a way to protect themselves.

2. The formation mechanism of color on tropical fish

The formation mechanism of color on tropical fish is mainly controlled by the pigments in **. Pigment pigments are divided into two categories: melanin and chromin. Melanin produces black and dark colors, while chromanin produces a wide variety of colors that resist the remnants of dust.

The formation of color pigments is mainly achieved in two ways. One is synthesized through nutrients in food, and the other is produced by the cells in the body themselves.

3. Does the color of tropical fish change?

Yes, the color of tropical fish changes with the environment. For example, some species of tropical fish become darker in the dark and more vivid in the light. In addition, the color of tropical fish can also change due to injury, stress, and disease.

In addition, the color of tropical fish is also related to their environment. Things like the color of the water and the color of the aquatic plants can have an effect on the color of tropical fish. Some varieties may become darker in shallow waters and brighter in deep waters.

4. How to make the color of tropical fish more vivid

The color of tropical fish is affected by environmental factors, so if you want to make tropical fish more vibrant, you need to provide them with the right environment. For example, keeping water clean and stable, providing adequate light and water temperature, providing them with food and nutrients, and so on.

In addition, you can also choose a brighter and brighter tropical fish as a pet. For example, red dragons, blue dragons, parrot fish, etc., their colors are more bright and bright, which can make people feel the fun of raising pets.
