CATDOLL : CATDOLL: Is loach a fish? Is loach a warm-water fish?

1. Is loach a fish?

Loach is a fish. Loach is small, slender, round, short, with small scales under the skin, dark blue in color, and a slightly cylindrical front section. The loach has a flat back, a round abdomen, a small head, a small, inferior mouth, and a horseshoe shape. It has small eyes without spines under the eyes, 5 pairs of whiskers, and extremely small, round scales buried under the skin. The back and sides of the body are gray-black, with many small black spots all over the body. There is an obvious black spot at the base of the caudal peduncle, and the other fins are gray-white. Loach mainly inhabits the bottom layer of various shallow and silty waters. Loach is widely distributed in China, Japan, North Korea, Russia, India and other places along the coast of Asia.

2. Is loach a warm water fish?

yes.

Loach is a warm-water fish with strong adaptability to the environment. It mostly lives in shallow waters such as ponds and lakes with still water or slow water flow. It usually lives at the bottom of the water. When the water is dry, it drills into the mud and can survive out of water. Loach can not only breathe with gills, but also breathe with skin and intestines. Breathing with intestines is a unique physiological phenomenon of loach. The intestinal wall of loach is thin and rich in blood vessels, which can assist breathing and gas exchange. When the water is dry in drought, it will dive into the 10-30 cm mud layer to "hibernate". A small amount of water can moisten the skin to maintain life. Loach is an omnivorous fish, and its food is animal and plant debris and microorganisms.

3. Is loach a fish? Why?

Loach is of course a fish! Here’s why

The definition of fish is a cold-blooded vertebrate that lives in water all year round, breathes with gills, and uses fins to assist in body balance and movement.

From the definition of fish, we can see that there are four characteristics to be called fish: 1. It is an oviparous animal with a backbone that lives in water all its life, and a few fish can stay on land for a short period of time. 2. It swims (moves) by swinging its tail and trunk and coordinating the fins. 3. It mainly breathes through gills. 4. Most fish have scales covering their bodies.

Loaches mainly live in water and like to find food in the mud. They have a strong ability to adapt to the environment and breathe mainly through their gills, but can also breathe through their skin and intestines. The skin of loaches secretes a lot of mucus and feels slippery, but it also has scales, which have degenerated into dense and fine scales. From this, it can be seen that loaches meet the characteristics of fish and should of course be considered fish.

4. Are loaches and eels fish?

Loaches and eels are fish.

Fishes are divided into two classes: jawless and jawed. The jawless class includes cyclostomes and armored fishes, and the jawed class includes placoderms, chondrichthyes, and ray-finned fishes. Most fishes are cold-blooded vertebrates that live in water all year round, breathe with gills, and use fins to assist body balance and movement. There are also some fish like African lungfish, mudskippers, and climbing perch that can survive on land for a long time, as well as snakeheads, eels, and gars that breathe with a single swim bladder. Although most fishes are cold-blooded animals, many sharks and tunas are semi-warm-blooded, while moonfish are warm-blooded.

7. Is loach a fish?

Yes, loach is a type of fish.

Loaches usually live in freshwater, they have long, slender bodies and scaleless skin, they can swim and sneak quickly. The scales of loaches are very small and difficult to see, and their gill covers can be completely closed to prevent mud and sand from penetrating into the respiratory tract.

Loach is one of the fish that humans eat and enjoy.

8. Will raising loaches in the fish tank affect other fish?

Putting loaches in the fish tank will affect the rest of the ornamental fish and pollute the water quality of the fish tank.

1. Loaches affect the rest of the ornamental fish in the fish tank. Loaches are very active at night, and their slender bodies make it easy for them to get in and out of the fish tank's landscaping. They are also very sensitive to vibrations, and will jump up and down in the fish tank at the slightest movement, affecting the rest of the ornamental fish.

2. Loaches pollute the water quality of the fish tank. Loaches like to snatch fish food, and they also excrete their own waste and secrete mucus. This process itself is a process that increases water pollution.

9. What kind of fish is loach?

Loach is a fish, a non-water fish, and a freshwater fish.

10. Are crocodiles and loaches fish?

Crocodiles are not fish, but loaches are fish.

Crocodiles are not fish but reptiles. They live in rivers, lakes and shallow bays. There is a membrane at the opening of their nostrils, like a door. When they dive into the water, the membrane closes to prevent water from flowing into their nostrils. The crocodile's body structure is very suitable for living in water. Only when it needs to bask in the sun or lay eggs will it use its strong limbs to slowly crawl onto land.

Loach is a bottom-dwelling fish that lives on the bottom of shallow waters with lots of silt, such as rivers, lakes, ditches, paddy fields, and ponds. It hides during the day and comes out at night. It has strong adaptability and can live in an environment rich in humus. When there is a lack of oxygen in the water, it can jump to the surface of the water and swallow air for intestinal breathing.
