With the development of society and the expansion of trade, rays began to spread, and more and more fish friends joined the ranks of raising rays. Hei Di Lei is loved by more fish friends because of its changeable patterns and plain price. I have been raising Hei Di Lei for three or four years, and I have accumulated some experience to share with you. I hope it will help beginners. Please correct me if there are any mistakes.
1. In fact, Hei Di Lei is a kind of fish that is easy to raise, and it is not as difficult to raise as some fish friends think. If you want to raise Hei Di well, you must first give it a comfortable environment. For example, you don't need a big fish tank to start raising three or four small fish. My experience is that a water level of 60 long and 40 wide (cm) is enough, so that Xiao Lei's mood will be more stable and he will not be anxious easily. It is also convenient to feed and change water. Of course, the water quality of small tanks is not as stable as that of large tanks. In fact, as long as there is no big fluctuation, it is still acceptable. It would be better if it could be connected in series with the vat. Filtering, cylinder opening, water supply, etc. It has been introduced by many predecessors' posts, so I won't describe it. The rest is to invite fish.
2. The choice of small rays is very important. Fish friends must not choose individuals who are too thin, too dark or sick, which is difficult for even veterans to adjust. Try to find some reputable players to raise fish. The fish they have treated are generally healthy. Most fish friends have problems after buying them, and many just buy unhealthy fish. Regarding the choice of quality, it is difficult to distinguish the future development because Hei Di has no hair color since she was born, but it can also be observed in some performances; My experience is that the lighter the background color, the more symmetrical the pattern and the bigger the circle, but the clearer the edge of the circle or pattern, the better. After that, the color contrast between the circle and the background color is stronger, and the three circles of lace are full (some mixed lace is incomplete). Of course, this is aimed at the popular white striped Hei Di. Everyone has different aesthetic standards, and there are many examples of ugly ducklings becoming swans. It would be better if you could see a kind of fish.
3. If you want Xiao Lei to grow fast, it is to change water. I always change one-third or one-fifth of the cold water every day (generally there is not much water in the small tank), and slowly add it through the trachea to feed the peeled loach. Later, I took the trouble to feed the shrimp. In a word, changing water is helpful to growth and not easy to get sick. When it grows to 15 and 16 cm, you can feed the chopped loach. Misgurnus anguillicaudatus should be bought as small as possible, which is easy to digest. After a period of breeding, the little ray has adapted to the local water quality, and can be moved into the vat with the increase of individuals.
4. About deworming; It is not recommended to drive the newly bought rays, because the rays after long-distance transportation are weak and have not adapted to the water quality and environment, and taking medicine at this time will make the situation worse. I always keep fish for a while, until they get used to repelling insects. What medicine to use depends on my acceptance. I usually choose water to live and be clear. Life in water is mild, which does little harm to fish, but the effect is not clear, so it is necessary to extend the administration cycle. It must be clear that it is adopted because of the low price, and the effect is average. I feel that the main way to avoid parasites is to work hard on feed. I never feed live bait. Misgurnus or shrimp are soaked in salt and then must be frozen for more than 24 hours. When feeding, they are completely frozen and washed repeatedly. I haven't felt parasites for years.
5. Black emperor penguins with a disc diameter of more than 20 can eat loach as their staple food. I always feed it once a day, and I never feed it too much when I am seven or eight full, which can reduce the burden of filtration and not be too fat (too fat will affect the reproduction of rays). Some people may think that feeding once a day will affect the growth of rays, but I don't think so. As long as I can eat enough, the individual size is mainly related to the size of the water body and the frequency of changing water. After all, fish didn't grow up in a day.
6. Generally, rays will be in estrus after one and a half years (individuals are ahead of schedule).
Some will encounter the phenomenon of male fish biting. It is best to isolate at this time, because the male fish is not too mature at this time, which will cause the skirt defect of the female fish and affect the ornamental value. It is best to wait until they are almost two years old before mating, so that the small fish born are healthy, the survival rate is high, and the female fish is not easy to have dystocia. It is generally difficult to meet a kind of infertile fish. As long as it is mature enough, it will generally give birth.
The rays raised by fish friends themselves will be easy to raise, and it won't take long to move the fish into the water. I always move the little ray to another tank after more than ten minutes out of the water, and there has never been a problem. Newborn rays can generally be fed without waiting for three to five days, and try to open their mouths with blood worms, generally eating early and eating late. After feeding for a week, you can feed shrimp instead. You may be reluctant to eat at first, but you can slowly accept it by feeding a small amount first.
7. There is another point that I think is crucial; That is, no matter how big the adult Hei Di feeds the loach, it is necessary to cut the loach. Don't feed the loach that is too big (the chopsticks are the best) and then fully thaw it. Washing can reduce the chance of enteritis and parasites. It is boring to feed and change water repeatedly every day. Fish friends should be fully prepared before departure, so that your loach will grow and breed healthily around you.
