1.5m What kind of fish should be kept in the fishbowl with sieve (1) If conditions permit, it is recommended to keep tropical fish. Actually, it is easier to raise tropical fish than koi fish. Please don't doubt this.
(2) It is best to raise low-priced small fish from the beginning, such as traffic lights and red nose scissors in the cage fish, second-line bream in bream, Dutch phoenix and so on. These fish are bright in color and gentle in temperament, which is very suitable for beginners to raise. Don't raise too many kinds of fish, limit one tank to no more than four kinds, and give priority to one kind of fish, such as traffic lights, which is a good match.
(3) If you plan to raise fish instead of grass, and the fish tank is relatively large, then raise the easiest and most beautiful map fish. Pig fish? It can be seen that it is lazy. Map fish have many colors and patterns, and you can choose according to your own preferences. Adding scavengers can help save some care.
If you want to raise aquatic plants and aquariums, you need to spend more time and wisdom on the initial establishment. After completion, it is more labor-saving and more suitable? Lazy? After that (it only takes one and a half hours a week to manage a colorful aquarium with a meter of 2 meters), you can plant stems with strong growth adaptability first, and then raise 200 traffic lights that are easy to raise (of course, you can also add some other favorite small fish), which is both easy and cheap. Even if you are temporarily frustrated again, the loss is not great. Don't underestimate the traffic lights.
One or two hundred together, the red light is on, the blue light is on, and you can swim in the green grass. Its imposing manner is very spectacular, and it is the best choice for beginners.
(4) If you are willing to pay more, you might as well raise colorful angelfish, plant aquatic plants and cultivate an ecological fish tank, whose ornamental value is not comparable to that of ordinary fish tanks.
How to raise fish in a fish tank 1, filtering;
Using filtration system, nitrifying bacteria are cultivated to purify water. Filter cotton and glass ring are generally used as filter materials. The filter cotton should be cleaned frequently, and it should be replaced with a new one after 1 month. Filter cotton is not expensive. 2 yuan each.
Step 2 provide oxygen
There is nothing to say about this, just adding oxygen to the fish tank. According to the actual situation, you can buy ultra-quiet ones, such as Japanese Yingguang Octopus Pump or German Han Yi.
3. Heating rod
Goldfish and tropical fish should have heating rods to keep the temperature constant. Because the temperature difference is too large, fish will get white spot disease. The power of the heating rod is selected according to the size of the fish tank.
Step 4: Feed.
Don't eat too much. Feed it regularly once a day and eat it within 3 minutes each time. Try to buy fish food, which is not expensive. Hua 100 bought 2 Jin of artificial feed, and there are 20 tropical fish at home. About half a year 1 kg.
Step 5 change water
Before changing water for fish, tap water should be dried for 24-48 hours, and the temperature must be paid attention to when changing water. Generally, the water change cycle is from 3 days to once a week, and the water change amount should not exceed half of the water in the cylinder each time. Change it twice a week at most.
The above are the usual management methods. There should be no big problems with fish, but after a period of time, you need to know some knowledge, such as the form of filtration, nitrifying bacteria, the concentration range of some harmful substances, and emergency treatment methods for fish diseases.
Experience of fish tank culture: The so-called fish culture needs water first, that is, the fish must prepare water suitable for their own survival before they can enter the house. The quality of water will directly affect the normal growth and development of fish. Tap water is generally used to raise fish at home. Because tap water contains bleaching powder, it is not appropriate to feed fish immediately. Let the water dry or let it stand for 2 to 3 days.
Continue to raise water: after the water is put into the fish tank, the filtration system is necessary, and the purpose of filtration is to remove the toxins produced by fish feces in the future. The filtration system is to increase oxygen and filter cotton. Fish shops and fishing gear shops generally sell them. Raising water is not a matter of three days or two. You should take your time and wait for a few days for the water to clear before buying fish into the tank.
Fish tank landscaping: placing pebbles, bottom sand or aquatic plants at the bottom of the water. Generally, do not plant grass in small water tanks, only put one or two plants of water grass. The vat can be made into rockery, turf, or stone or wood to create a small underwater ecological environment. Of course, this process is not a matter of two or three days. When all kinds of plants take root and sprout, they will start the cycle of troubles. After a day's cycle, fish can be put in.
Stocking small fish: When everything is ready, you can raise fish. Generally speaking, it is not recommended to raise big fish, and the number should not be too large. There should be three or five small tanks. If the fish tank is bigger, you can raise more fish. Small fish cannot be kept with fierce fish. Even those with landscaping can't keep evil fish, because it will destroy the underwater ecological environment that we have painstakingly managed.
