First, the basic knowledge of the little angelfish
The small angelfish belongs to the smaller species of angelfish, with a body length of less than 18 cm, and nearly 30 species are common. Because it is cheap, good-looking and well-raised, the little fairy is very popular among the ornamental fish in the sea, its temperament is mild, it can adapt to the aquarium life, and it can live peacefully with most marine creatures. However, many small immortals will harass and even eat soft corals, especially brains and buttons, so there is a trade-off with coral polyculture. Generally do not harass and nibble on mushrooms and leather, can be mixed.

Second, the breeding of small angelfish
Different species of small angelfish, the difficulty of raising is different, the following introduction of the basic methods and experience. The equipment takes my large bullet cylinder as an example, using side filtration, and the water body is about 260 liters.
(1) Fish tank equipment and materials
1. Fish tank body
Choose a square glass fish tank of 100-200 liters, if you want to consider the aesthetics and polyculture (different fish polyculture, to choose a reasonable polyculture fish), you can use a larger fish tank. It is best not to cover the fish tank for novices, which is convenient for management.
2. Filtration
Side filtration, back filtration and bottom filtration are all acceptable, but top filtration, external filter boxes and ATS should not be used as much as possible, for pure fish farming, they are too troublesome and the effect (stability and timeliness) is not good. The bottom filtration of the mixed tank is better, and the back filtration of the pure breeding little immortals is more convenient. The filtration should be set according to the fot, and can also be divided into 3 compartments, the first compartment is fed (sewage), the filter cotton, eggs and heating rods (water cooling), the second compartment is placed with glass rings, crushed living stones and algae tanks (if space is available), and the third compartment is placed on the water pump. The pump can choose 5-10 times the water volume in the cylinder per hour, and the bottom filter should choose a larger pump. My tank is a 15 watt pump of choice. With a larger pump, it is also possible to eliminate the need for flow generation. The filter material is glass ring and crushed living stone, the glass ring is the residence of nitrinated bacteria, which can efficiently convert ammonia and nitrite, and the crushed living stone can provide biodiversity, and has the effect of converting nitrate, stabilizing PH and calcium. Each 10-20 liters of water is dispensed, and half of the same can be. Pure culture of small angelfish filter cotton is dispensable.
3. Protein separator
Be sure to use eggs, because the small immortal excretion is a lot, some small immortals are also very sensitive to nitrate, so try to choose eggs with large processing capacity or large pump power. Egg selection processing capacity is 2-3 times the water body or pump per hour flow rate of 10-20 times the water body in the tank is better, I am using nq80 eggs, the mixed tank should consider the use of larger eggs.
4. Lighting
Lighting intensity should not be much, according to 20-50 watts per hl, fluorescent lamps, LEDs can be, the color is cool and white is more appropriate. Coral polyculture tanks should be configured according to the requirements of corals. It is also possible to use uneven configuration of lamp beads, which can not only strengthen local illumination for corals and algae, reduce the lighting electricity of the whole cylinder, but also form a dark area to facilitate the hiding of timid immortals. The lighting time is adjusted from 10:00 am to 10:00 pm for easy viewing.
5. Constant temperature
22-28 degrees. I use a 300-watt heating rod, which is constant at about 24 degrees all year round, and does not use the heating rod in Kunming from April to August (in order to save electricity), but the temperature fluctuates. Kunming summer temperature is not high, cooling and water cooling has not been used. Other regions can increase water cooling depending on the climate. Note that some small immortals are not tolerant of high temperatures, such as flame immortals and fire back immortals.
6. Create flow
Yes, the pump can be used in a larger way.
7. Other creatures
Mushrooms, leather, living stones, algae and tool fish, shrimp, snails, etc. are best matched with a little, not only better ornamental, but also can reduce the sense of urgency of the little angelfish, and also help maintain water quality. My tank will be equipped with a few mushrooms, leather and bubbles, hammers and other good corals, pay attention to when there is a small angelfish to eat a coral, to remove the coral, otherwise you should fish away the angelfish; will also be equipped with a few cleaning snails, clean shrimp and shrimp tigers, etc., with a few living stones, you can also use plastic rockeries for landscaping; with several high algae.
8. Others
Thermometer and hydrometer must be present, and the specific gravity is maintained at about 1.020. Sea salt is generally ok. Local tap water is not too bad to use. Various test agents are optional. Experience can be used less, no experience can be used more. I have not used it, generally judging by the state of fish, corals and algae.
The small fairy tank NO3 can not be too high, try to exceed 30, PO4 should not exceed 0.05.
(2) Open the cylinder to raise water
The structure of the filtration system of my fish tank is for reference only.
nq80 egg points, the sewage cup is too high to make a short one. 20 watt water pump. 300 watt heating rod. 20 liter glass ring.
The lights are DIY's 2 15 watt LEDs, half blue and white lamp beads, and the fish tank lid dissipates heat.

(3) Selection of small angelfish
1, novices recommend step by step, it is best to buy a small fairy fish raised in the opening, the appearance and color of the body shape should be selected normal, it is recommended to raise 1 per species, first raise 2-3 varieties. You can breed demons and clowns. Polyculture of daisen, hanging class (can no longer raise algae) is recommended to try after having experience.
2. Selection of varieties.
In my experience, the Fire Fairy, the Yellow Bride, the Blue Lightning, the Red Lightning, and the Fire Back Fairy are easier to raise. White-spotted immortals, colorful immortals, tiger-striped immortals, and stone beauties are medium in difficulty in breeding. The Qilin Immortal and the Eleven Immortals were troublesome and more difficult to raise. Fire Fairy, Blue Lightning, Red Lightning, and Fireback Fairy are less likely to harass soft corals. Yellow brides, colorful fairies, and white-spotted fairies prefer to harass soft corals. Stone beauties, tiger fairy, and eleven fairy will eat soft coral. The Flame Immortals, The Red Lightning, and the Eleven Immortals were more timid.
3. State judgment.
When picking fish in the fish shop, the abdominal fin has been fully unfolded, the fish body is strong, the body surface is brightly colored, there is no pathology, the breathing is leisurely, the activity is active, the challenge is everywhere, the pecking is everywhere, and it is not afraid of people.
(4) Breeding of newly introduced small angelfish
1. Preparation before fishing in the fish tank
If it is a new cylinder and new filter material, it takes more than 30 days to raise water, and it is necessary to explode the algae and algae albino before the water is raised.
2, new fish over the water
to temperature. Put the fish in the tank, usually 10-30 minutes. The parallax temperature difference size is adjusted appropriately.
Salinity. Measure the salinity of seawater in the bag, adjust the salinity in the cylinder, and try to be consistent with the bag.
Mix with water. Continuously introduce the water in the tank into the bag and drain the water from the bag (discard) for 10-30 minutes. Depending on the temperature and water quality difference, the time is adjusted appropriately. I used the air pump's trachea inlet and drainage, and replaced the amount of water in the bag by about 1-8 times.
If there is little difference between temperature and water quality, it can be mixed with temperature and water at the same time.
The fish are then fished into a tank or isolation box (to prevent fights and facilitate treatment) and the water ends.
3. Fix the water and train the new fish
Little angelfish are fed
The baby angelfish is not fed on the first day, and can be fed with hatched shrimp after one day, and the easy-to-raise varieties will generally open their mouths and feed according to the adult fish after a week. The adult fish of the little angelfish can not be fed for 3 days at the beginning, and then see if it will nibble on stones, tank walls or algae, and then starve it until it is nibbled. Then find the place where it often hides, usually in the corner or in the pile of living stones, find the path it often goes in and out, and quietly clear out a small open space. Put some pelleted feed in a straw in the open space, wait for it to eat, and suck it away without eating for 15 minutes, 3 times a day, until it starts to taste. Then reduce the pellet feed and eat the main amount at a time until the normal amount (the amount of fish eye size per time) is eaten. Then slowly change the feeding location and gradually move to the vicinity of large open spaces. Finally, feed from the surface of the water above the open space and complete the training.
After the little angelfish eats the pellet feed, the larger fish tank In order to prevent the feed from drifting around and causing waste and bad water, it is best to add a feeding ring. First put the feeding circle in the original feeding place, after a few days slowly change the feeding location, gradually transfer to a large open space or place with a small water flow, and then regularly and quantitatively feed in the feeding circle, then the little angelfish will take the initiative to wait for feeding in the feeder.
Little angelfish after training
Fish infected with other viruses, bacteria or parasites cannot enter the tank, and should be isolated and quarantined for about a month, and can only enter the tank after recovery.
4, not easy to open the mouth of the small angelfish training.
Put some corals and shellfish in a bad state or cheap in the tank, and the corals are given priority to brains and buttons. It is better to put some living stones full of algae, hair pots, sea squirts, garbage sunflowers and other creatures. Observe what the fish likes to eat, then take the uneaten away and leave it to eat. Then put some feed on the creatures that the little angelfish likes to eat (such as corals and shellfish), and the little fairy will eat some feed when pecking. Slowly increase the amount of feed and normal particle size, and finally even cover the corals and shellfish. When the fairy eats the coral and shellfish, it will generally adapt to eating pellet feed. Then slowly change the feeding location and gradually move to the vicinity of large open spaces. Finally, feed from the surface of the water above the open space and complete the training.
Experienced and like to challenge the difficult to raise small angelfish aquarists, should try to raise difficult and timid, so that it is easy to train food, and it is easy to raise other small fairy fish in the future, otherwise it is difficult to raise and timid is not easy to train and starve to death.

5. New fish culture
Fish that have been fixed, opened, trained and quarantined can be raised alone or in groups or polycultures after entering the tank. Small angelfish of different colors are easy to polyculture, and small angelfish of similar colors are easy to fight. Paired fairy fish and baby angelfish can be bred in groups.
Fish should be paid attention to the first timid fish and then other fish. It is safer to enter the new fish after turning off the lights at night, and it is necessary to pay attention to whether there will be a fight, otherwise it is necessary to isolate the fierce fish for a period of time. If you isolate many times and fight, you have to replace the fish you don't like.
Slowly adjust the salinity to normal salinity. I am adjusted to 1.020-1.022, general fish farming can be on the low side.
Feed 3 times a day, preferably with fewer and more meals, to restore physical condition. Feed can be adjusted from time to time or live feeding may be added to regulate appetite.
The performance of yangding: no pests and diseases for more than 30 days, leisurely breathing, active activity (some timid people often hide from the side is normal), pecking everywhere, not afraid of people and asking for food (this is an important sign of cultivation), and have a strong behavior of food protection.
After rearing, the small angelfish can be fed once a day, and the amount of feed that is the size of the fish's eyes can be fed each time. Want to challenge the breeding of small angelfish, breeding fish should be fed a highly nutritious feed, 3-5 times a day, each time to eat within 10 minutes as a good, it is recommended to eat less and more meals, is conducive to the growth of breeding fish. At present, no one in China has really successfully bred small angelfish. Foreign countries have successfully bred small angelfish very early.
(5) Raising and maintenance of small angelfish
1. Daily maintenance
Novices recommend observing the creatures every day, feeding the fish once, and cleaning up the dead creatures. Once a week, water quality is tested, water is changed (5-10%), tanks are wiped, filter cotton is washed, eggs are cleaned, corals are fed, and algae are sorted. Every six months, the pump, the flow, the egg are cleaned, the filter media is cleaned in batches, and the living stones are replaced in batches. Check the lighting once a year, heating rods.
After having experience, you can not change the water as often as I do, generally the egg is wet, half a cup of dirty water every day, so it is necessary to replenish water every day, mainly to make up the water and evaporated water of the egg, while supplementing trace elements, which can be supplemented according to the specific gravity of fresh water or seawater. On a business trip or out of the house for a while, adjust the egg distribution into dry bubbles, and then lower the specific gravity. My fish tank has a lid, so I don't have to hydrate for ten days, just add an automatic feeder. After the feeding is normal and stable, the polyculture tank can change 10% of the water per week, and the pure small fairy tank can change 10% of the water every month.
2. Experience with algae
Seaweed is also very good to look at when it is well raised. The algae in my tank generally does not care, whether it is high algae or low algae, but too much or affect the growth of corals to remove part of it, so the tank is basically full of various algae (equivalent to natural ATS). Algae can absorb a large number of nutrient salts (including ammonia, nitrate, phosphate, etc.), naturally completing the nitrogen cycle, so it can maintain good water quality with less water change. There are also many small organisms growing in the algae, such as snails, insects, shrimps, crabs, etc., which also provide shelter for a variety of vulnerable microorganisms and small life. Their eggs and larvae provide rich food and living conditions for the fish, shrimp and corals in the tank, and provide a stable ecological environment, which is very beneficial to their survival and growth.
Many small angelfish are prone to violent death, which is estimated to be related to fright, lack of trace elements and unbalanced feed nutrition. Little angelfish like to eat algae, but also like to hide in the living stones with algae, raising algae can reduce the risk of violent death.
After the little angelfish is raised, you can slowly join the big angelfish to lay a good foundation for the standard FOT.
