The breeding and management of tropical fish is a comprehensive work. Including water, feeding, heat preservation, etc. It requires mastering the living habits of different kinds of tropical fish and improving the living environment of tropical fish.
1, feeding device
In addition to aquarium and water quality filter, there are water quality recirculation filter, heating device, oxygen increasing device, lighting device, water pumping device and so on. A single aquarium can use a small filter pump, 100-200W heating pipe, single-hole and double-hole air pump, fluorescent lamp and small submersible pump. For multiple aquariums, the installation is complicated. There are two kinds of circulating filtration devices for tropical fish: in-box filtration and out-of-box filtration. Small aquariums mostly use in-box filtration or low-power circulating filtration pump, while large aquariums mostly use out-of-box filtration. The heating device of tropical fish has various electric heating tubes with different powers, such as 100W, 200W, 500W, 1000W glass or stainless steel electric heating tubes, which can automatically adjust the temperature. The heating device of large fish house adopts heating, air conditioning, electric heating, etc. Provided by the boiler room.
The aerobic devices of tropical fish include single-hole air pump, double-hole air pump, four-hole air pump and turbo oxygenator. For a single aquarium, you can choose a single-hole air pump. For multiple aquariums, you can choose two-hole or four-hole air pumps. Single-hole, double-hole or four-hole air pumps are all made of plastic materials, and the oxygen flushing in water is completed by the movement of rubber plugs. The rubber stopper will rupture or age after long-term use and should be replaced in time. Turbine oxygenator can be used to raise tropical fish in a large area. Made of metal material, with low failure rate and long service life. In addition, the auxiliary oxygenation device includes gas stone and oxygen pipeline.
The main lighting devices for tropical fish are fluorescent lamps, halogen lamps and mercury lamps. For the lighting of a single aquarium, sometimes underwater colored lights can also be used. It is a small glass tube, which can be directly placed under water and adsorbed on the glass tube wall. Its lamp tube can emit red, blue, green, white and other different colors, and the beautification effect is good.
Most of the pumping devices for tropical fish use low-power submersible pumps made of all plastic materials, which are small in size and light in weight, with power of 200W, 500W, 1000W, etc. , its lift is 5- 10 meter. When in use, it can be adsorbed on the cylinder wall, and the water in the aquarium can be drained in a few minutes, which is safe and reliable.
feed
(1) Foraging habit: The feeding water temperature of tropical fish is generally controlled between 24℃ and 28℃. In this temperature range, tropical fish have a strong appetite and grow rapidly, and are always maintained in a relatively stable state without being affected by external temperature changes. The bait of tropical fish includes fish worms, earthworms, earthworms, Tenebrio molitor, small live fish, pellet feed and so on. There are many kinds of tropical fish, and their sizes vary greatly, so the bait selection of different kinds of tropical fish is also different. Tropical fish with a body length of 3- 12 cm mainly feed on turtles, supplemented by earthworms, red worms and Tenebrio molitor. For tropical fish with a body length of 12 cm or more, soft-shelled turtles are small and have poor palatability, so they should choose larger bait, mainly red worms, water worms, Tenebrio molitor and small live fish. Tropical fish mainly feed on animals, and small species can also be domesticated as particles, and a few fish are mainly plants.
(2) Feeding frequency: The feeding amount of tropical fish should be determined according to the size and quantity of fish. Generally, domestic cultured tropical fish only need to be fed 1-2 times a day, and the feeding amount should be eaten within 5- 10 minutes. When raising tropical fish in large quantities, feed them 2-3 times a day; During the breeding period, fish are generally fed 3 to 4 times a day. Tropical fish, due to their small size and limited food intake, should be 7-80% full at a time. Increasing the frequency of feeding will promote the rapid growth of turtles. In most tropical fish, turtles are the main bait. When entomology is the main bait, the feeding amount should be controlled within LO-30 minutes. When the bait is mainly water earthworm, the feeding amount should be controlled within 5- 10 minutes, and each person should feed it for 2-3 times, and the fed water earthworm should be washed clean. When the bait is mainly small fish and shrimp, in principle, we should eat more meals and eat less. When tropical fish are replaced with new bait, the amount of bait should be gradually increased from less. Tropical fish should stop feeding 1 ~ 2 days before transportation.
Use water
(1) water exchange: water exchange refers to partial water exchange, which is a simple and effective method commonly used in tropical fish culture. Before adding water, turn off the power of the heater, air pump, circulating filter pump and other electrical appliances in the aquarium, and then wipe off the moss attached to the glass wall or scenery of the aquarium with gauze. After letting the water stand for 15 minutes, all the suspended substances in the water sink to the bottom of the cylinder, and gently suck out the dirt at the bottom with a rubber tube. Generally, the sucked water accounts for about 1/4 ~ 1/3 of the total water. Then the prepared fresh water with the same temperature is slowly injected along the cylinder wall.
(2) Changing water: Changing water refers to changing all the incoming water, which is the simplest and most effective method to change the water quality, but the workload of changing water is large, especially when the aquarium is small in scale and beautiful in scenery, and the process is complicated and cumbersome. Before changing the water, cut off the power supply of all the small appliances in the aquarium, take out all the fish and scenery, and drain the water. After the aquarium is cleaned, put away all the scenery and put it in fresh water for later use.

What do you need to know to raise tropical fish?
Generally speaking, those who are carefully raised and properly managed; Pay attention to stocking density and master the change of water temperature; Keeping good water quality, fresh bait, qualitative, quantitative and regular feeding can raise ornamental fish. The following are the essentials that must be mastered in raising ornamental fish for your reference.
1 If you want to raise fish well, you must first learn to buy fish: healthy fish swim in the middle and lower layers of water (except the upper layer) for food, swimming naturally and leisurely, and the tail fin is clear and elegant. Sinking to the bottom, floating head, swimming and struggling, trauma, white hair and white spots, thick caudal fin, turbidity, severe bloodshot, dark body color, turbid eyes, being single and alone, refusing to eat or wiping the jar with your body are all sick fish, so you must not buy them.
When buying, large and medium-sized fish with strong vitality should not only be inflated to keep oxygen, but also be covered with black bags to reduce external interference. Valuable fish should be bagged separately to avoid injury caused by mutual contact. Pay attention to heat preservation when buying fish in winter.
Don't rush to put the tropical fish into the jar after buying it home. Soak the plastic bag containing fish in the fish tank for ten to twenty minutes before opening it, so that the water in the tank can flow into the bag for many times and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and quality. If there is a light, turn it off. In the dark, fish are quiet and not easily frightened.
Tropical fish are most suitable for living in the range of 24-28 degrees, and can live normally when it reaches 32 degrees in summer, but if the temperature suddenly changes too much, tropical fish can't adapt. Therefore, before you buy fish, you should not only adjust the water temperature of the fish tank, but also pay attention to the fact that the deviation between the water temperature of the fish tank and the water temperature of your fish tank should not be large, which is generally allowed within 4 degrees. If the water temperature difference between the two is too big, I'd rather not buy it for the time being and wait until the adjustment is close.
You can't change too much water at a time, which will lead to water quality discomfort. Water quality includes pH value, hardness, residual chlorine, dissolved oxygen, nitrate, sulfide, protein and turbidity. Tropical fish have adapted to live in the original water quality, all changed water, and suddenly changed the water quality, so they can't adapt, and the water quality is out of balance, which makes them fall and get sick. If you need to brew the bottom and wash the tank, you should also keep most of the old water. After cleaning the water tank, put the water back into the water tank and add new water.
Pay attention to the density of fish. Tropical fish like large space for activities. Novices often buy their favorite fish when they see it. They seldom care about how many fish can be raised in the tank. Even if they ask the fishmonger for advice, can they ask you to buy less for the benefit? Usually, fish with the length of 1 liter of water are raised 1 cm. If your fish tank is filled with 100 liters of water, it is safer to feed tropical fish up to 10 cm long. Individuals insist on 1.5 as the control target. In a larger space, fish are more active, stronger and brighter in color. Excessive density easily leads to hypoxia and deterioration of water quality, which is the main cause of illness and death of tropical fish.
7 how to feed. The most important thing to pay attention to in small tank fish farming is to control feeding, once or twice a day, and it is advisable to eat it within 3 to 5 minutes. Feed less in rainy days and not at night. Fish need to consume more oxygen when digesting food. The air pressure is low in rainy days and at night, and the dissolved oxygen in water is low. In this case, feeding the fish may lead to serious hypoxia in the water and kill the fish. Most dead fish occur at night, and severe hypoxia in water is one of the main reasons.
The bait must be clean, which is the easiest thing for beginners to ignore. Feeding unclean bait can easily lead to fish diseases. It is recommended to buy brand frozen fresh foods produced by professional companies, such as red worms and bumper shrimp. Although live worms such as earthworms and mealworms are the favorite of tropical fish, they all grow in polluted water environment and are easy to die and rot in temporary culture. So, be careful to put in live food.
Keep the water clean. Tropical fish will consume a lot of oxygen, discharge a lot of waste, pollute water and breed germs after eating. To keep the water clean, a filter should be installed. If the fish are raised in a bare water tank, it is necessary to remove the educts from the bottom of the water tank and replace one tenth or a little more old water every day, especially in summer. The ecological tanks for fish and aquatic plants only need to change the water of 1/3~ 1/4 once a week. The filter can be designed with aeration, and filtration and aeration can be carried out at the same time, which not only purifies water but also supplements oxygen. However, the water tank cannot be inflated.
10 cannot be launched with oil. Oil pollution will float on the water surface to isolate the air, so that the oxygen in the water can not be replenished, leading to the death of tropical fish due to lack of oxygen. Eating meat and even applying hand cream will bring oil into the water, so be careful to avoid it. Accordingly, fish tanks should be far away from places where oil and natural gas are produced.
1 1 It's best to start with fish with low prices and easy to raise, accumulate experience and then raise rare species, so as to be handy and successful.
What tropical fish can be raised without heating with a heating rod? What are the ornamental fish that are not heated by heating rods, that is to say, the fish that are relatively cold-resistant? There are usually goldfish and koi fish. Feeding method of goldfish: Although goldfish is an omnivorous fish completely domesticated by human beings, it can directly affect the growth and development of goldfish like crucian carp and other fish.
You don't need a heating rod to raise tropical fish. If it's in Guangdong and Hainan, it's not needed. Otherwise, it is basically needed, unless the air conditioner is turned on as soon as it is cold, and it has been above 20.
What tropical fish can be raised without heating? Tropical fish can be used in summer, but unlike normal fish, a temperature-changing animal can automatically adjust its body temperature, but when the outside temperature is too low, it can't stand it and die, so it must be heated in winter.
Can I raise tropical fish with heating rods in my fish tank? As long as I have the filter, I can improve the water and heating rods, and I can improve some tropical fish! Only heating rods are not enough!
List of tropical fish with low temperature tolerance What goldfish can you raise without heating tropical fish with a heating rod in winter? Koi fish is the most common one.
Other tropical fish, as the name implies, are tropical fish. How can they bear the low temperature?
Unless you are a breadwinner, grass carp, crucian carp, carp, silver carp and so on.
What tropical fish can you raise without heating with a heating rod in winter? This is an idiot question.
If your indoor temperature can reach above 26 degrees, you can guarantee that the fresh water you change can reach this temperature every time, so you naturally don't need to heat it.
Whether to use heating is not a matter of season, but depends on your indoor temperature.
What tropical fish can be raised by heating with a heating rod? Generally, the temperature needs to be above 20 degrees, and about 28 degrees is more suitable. In China, the temperature in most areas will be lower than this in spring, autumn and winter. So most of them need heating rods.
Will the tropical fish raised at home die overnight due to lack of oxygen? Specifically, specifically.
My straw jar has never been oxygenated since it was opened, and it is alive and well.
My seawater tank eggs are oxygenated for 24 hours.
