CATDOLL : CATDOLL: Can koi and tropical fish be raised together?

Can koi and tropical fish be raised together?

It is not suitable to be mixed with tropical fish for the following reasons:

1. Koi is very gentle in nature, and the water quality environment in which it lives. Koi can live in water temperatures of 2-30℃, and the most suitable water temperature for survival is 21-27℃. In this temperature, Koi's feeding ability is very strong. Koi likes to live in slightly alkaline water and water with low hardness. They prefer to swim in groups and have a strong ability to adapt to the environment.

2. Koi are large ornamental fish, with a relatively large body and a relatively long lifespan. Most importantly, they are gentle and kind, so when choosing fish to keep with them, you must choose fish with a relatively gentle temperament, otherwise the koi are very likely to be attacked and easily injured.

3. Koi also don't like to be frightened too much. When changing water or adjusting the water quality, the pH should not exceed the specified range. Koi can withstand a sudden change in water temperature of 2-3℃. The range of pH fluctuation that can be tolerated is less than 0.5.

Precautions for mixed breeding of koi

1. Choose fish that can survive at a temperature close to that of koi. However, be careful to avoid the situation where big fish eat small fish. When choosing fish to raise together with koi, the fish should not be too small.

2. When raising mixed fish, the food habits of the fish can be random, because koi are omnivorous.

3. Since koi have a very gentle temperament, when choosing fish for mixed breeding, you should not choose ones that are too ferocious. You should choose ones that can get along well with koi and have very little or no aggressiveness.

Can Koi fish and catfish be kept in the same fish tank?

The scavenger can be raised with koi. However, the temperature should not be too low. The scavenger is a tropical fish. If the temperature is too low, the scavenger cannot bear it. If the temperature is too high, it is not good for the koi. At the same time, the scavenger will suck the mucous membrane of the koi and will never repent. However, if the individual difference is too large, the koi will also bite the scavenger.

If the temperature of the fish tank is not too low, you can raise fish together. If the fish tank is not clean, you should start with improving the filtration. You can add a filter. The scavenger plays a small role. The scavenger excretes a lot, which will make the environment worse. Nowadays, people have made the scavenger too magical. It is very difficult to use and is far inferior to snails. It is recommended to improve the filtration or release a few large snails. The small ones will be eaten.

The scavenger is an omnivorous fish that sucks algae, benthic animals and garbage in the water, and can also swallow a large number of fish eggs and fry. In the aquarium, it often attaches itself to stones and glass to stabilize its body and suck algae, and also looks for benthic animals (such as water earthworms). For small particles of feed floating on the water surface, it will suck them by sticking its belly to the water surface. Its mouth is like a vacuum cleaner, sucking all the fish feces and green plants into its stomach.

Cleaner fish form:

1. The body of the scavenger fish is streamlined, with small eyes, a low mouth, a prominent forehead and a thick snout. The upper and lower lips each have two lobes of teeth on the left and right.

2. Teeth are brush-shaped. There is a missing barbel at the corner of the mouth, one on each side. The gill rakers are like dense combs. The body is covered with black patterns, and the black stripes are clear. The base of the pectoral fin can make a sound similar to that of the yellow catfish. There are two dorsal fins, no lateral line scales, and only four rows of large scales on the sides of the body.

3. The sexes are clearly distinguished: the female scavenger has a wide dorsal body, soft and smooth barbs, a lighter body color, and short and round pectoral fins; the male scavenger has a narrow dorsal body, hard and rough barbs, a darker black body color, long and pointed pectoral fins, and a star.

4. The scientific name of the "scavenger" is "king heteromorpha". It is native to Latin America and is also known as the sucker fish, garbage fish, and angler fish. It is large in size and has well-developed lips like a sucker. It is named because it feeds on various underwater garbage and is often mixed with various fish. Adult scavengers have a huge appetite. In addition to algae such as moss, it also feeds on the eggs of other fish. It can eat 3,000 to 5,000 eggs a day and will also swallow fry. In the aquarium, it often attaches itself to stones and glass to stabilize its body and sucks algae and moss.

5. When nutritious and delicious fish worms and fish food are placed in front of them, they will definitely not be interested in the leftover bait and dirt. The scavenger is not a very good ornamental fish species. They rest during the day and move at night. They will gnaw on the water plants and bite them like fishing nets. In addition, if the fish is sick, they will attach to the fish's body at night and gnaw on its wounds. The scavenger's excrement is very large, not only is it not clean, but it will make the situation worse.

You can keep them together, but the temperature index cannot be too low. If it is too low, the scavenger can't stand it. If it is too high, it is not good for koi. And the scavenger's cleaning effect is not very good. The scavenger only eats some moss and steals fish food. It is better to strengthen the filtering effect and put two 15W upper filters. The effect is good. My small tank keeps budgies and moss-clearing rats. Add together a lot. I haven't changed the water for half a year. It all depends on the filter.

If the temperature is not too low, you can raise them together. The fish tank is not clean, mainly because it is closed. You should start by improving the filtration. The scavenger plays a small role. The scavenger excretes very slowly and will make the environment worse. Nowadays, people have made the scavenger too magical. It is very difficult to use and is far inferior to snails. It is recommended to improve the filtration or release a few large snails. The small ones will be eaten.

I don't know how others raise them, and I don't know if the two above have raised them this way. But I raise Koi and scavengers together, and they are harmonious. My scavenger is about 15 cm. I haven't heated it yet, but it will be easy to heat in a few days. Because I am in Harbin.

You can use fish tank bleach. It is not recommended to use a scavenger because it will compete with the koi for food and eat the koi's eyes.
