1. Breeding equipment

In addition to aquariums and water filters, tropical fish breeding equipment also includes water circulation filtration equipment, heating equipment, oxygenation equipment, lighting equipment, and pumping equipment. wait. For a single aquarium, a small circulating filter pump, a 100-200W heating pipe, a single-hole and double-hole air pump, a fluorescent lamp, a small submersible pump, etc. can be used. For multiple aquariums, the equipment is more complex. There are two types of circulating filtration equipment for tropical fish: in-box filters and out-of-box filters. Small aquariums mostly use in-box filters or low-power circulating filter pumps, and large aquariums mostly use out-of-box filters. Heating equipment for tropical fish includes various electric heating tubes with different powers, such as 100W, 200W, 500W, 1000W glass or stainless steel electric heating tubes with automatic temperature adjustment. The heating equipment for large fish houses uses heating and air conditioning delivered by the boiler room. , electric heating, etc.

Aeration equipment for tropical fish includes single-hole air pumps, double-hole air pumps, four-hole air pumps and turbine oxygenators. For a single aquarium, a single hole air pump is available. For multiple aquariums, a two-hole or four-hole air pump is available. Single-hole, double-hole or four-hole air pumps are made of plastic materials, and they use the movement of the rubber stopper to complete the oxygen flushing work in the water. After long-term use, the rubber stopper will crack or age and must be replaced in time. For raising tropical fish in a large area, a turbine oxygenator can be used. It is made of metal materials, has a low failure rate and has a long service life. In addition, auxiliary oxygenation equipment includes air stones, oxygen pipelines, etc.

The lighting equipment for tropical fish is mainly fluorescent lamps, in addition to halogen lamps, mercury lamps, etc. For the lighting of a single aquarium, underwater colored light can sometimes be used. It is a small, fully enclosed glass lamp that can be placed directly underwater and adsorbed on the wall of the glass tank. The lamp can emit different colors. Such as red, blue, green, white lights, the landscaping effect is better.

The water pumping equipment for tropical fish mostly uses low-power submersible pumps made of all plastic materials. It is small and light, with power sizes of 200W, 500W, 1000W, etc., and its head is 5-10 meters. When used, it can be It is adsorbed on the tank wall and can pump out all the water in the aquarium in a few minutes, which is safe and reliable.

2． Feeding

(1) Foraging habits: The water temperature of tropical fish is generally controlled between 24-28℃. Within this temperature range, tropical fish have a strong appetite and grow rapidly. They are not affected by the outside world. The influence of temperature changes always maintains a relatively stable state. The food for tropical fish includes fish worms, water worms, fiber worms, mealworms, small live fish, pellet feed, etc. There are many varieties of tropical fish, varying in size, so the bait selections for different species of tropical fish are also different. For tropical fish with a body length of 3-12 cm, the main food is turtles and insects, supplemented by water earthworms, red worms and yellow mealworms. For tropical fish with a body length of more than 12 cm, turtle worms are small and have poor palatability, so slightly larger baits should be selected, mainly including red worms, water earthworms, mealworms, small live fish, etc. Most tropical fish feed mainly on animal feed, and small species can also be domesticated to feed mainly on pellet feed. However, there are very few fish that feed mainly on plant feed.

(2) Frequency of feeding: The amount of feeding for tropical fish should be determined according to the size and quantity of the fish. Tropical fish raised at home generally only need to be fed 1-2 times a day, and the amount of feed should be eaten within 5-10 minutes. When raising tropical fish in large quantities, feeding needs to be given 2 to 3 times a day; for brood fish during the breeding period, feeding is generally required 3 to 4 times a day. Since tropical fish are small in size and have limited food intake, it is appropriate to feed 70-80% of the food each time. Increasing the number of feedings will promote rapid growth of the turtles. Most species of tropical fish feed mainly on turtles and insects. When the bait is mainly worms, the feeding amount should be controlled to be eaten within 10-30 minutes. When the feed is mainly water earthworms, the feeding amount should be controlled to be eaten within 5-10 minutes, and each person should feed 2-3 times. The water earthworms fed should be rinsed clean. When the bait is mainly small fish and shrimps, in principle, it should be fed more often and less frequently. When replacing tropical fish with new bait, the amount of feed should be gradually increased from small to small.

Before transporting tropical fish, bait should be stopped for 1 to 2 days.

3. Water

(1) Watering: Watering refers to partial water change. This is a simple and effective method often used in raising tropical fish. Before adding water, turn off the heater, air pump, circulation filter pump and other electrical appliances in the aquarium, then use gauze to wipe off the moss on the glass or scenery on the walls of the aquarium, and let the water sit for 15 seconds. After a few minutes, all suspended matter in the water will sink to the bottom of the tank, and use a rubber tube to gently suck out the dirt at the bottom. - Generally, the amount of water sucked out accounts for about 1/4 to 1/3 of the total water volume. Then slowly pour the prepared new water of the same temperature along the cylinder wall.

(2) Water change: Water change refers to changing all the feeding water. It is the simplest and most effective way to change the water quality, but the workload of changing the water is relatively large, especially when the aquarium is small and has scenery. , the process is complex and cumbersome. Before changing the water, turn off the power to all small electrical appliances in the aquarium, take out all the fish and scenery, and drain the water. After the aquarium is rinsed, put all the scenery away and put in new water for later use
