What does the crown ray eat?
Raccoons are extremely lively fish and should be fed at least once a day. If you can feed them 2-3 times a day, there is no problem. However, it is necessary to consider whether the filter material in the fish tank can match the feeding times for many times. Therefore, it is best to use a circulating filtration system with good function and effect. This paper introduces some kinds of food suitable for freshwater rays, in addition to the commonly used bait in China, there are also foreign materials for reference:

Live fish of Zhu or other races, fresh fish slices, fresh salted shrimp, grass shrimp or crayfish, red-banded worms or nematodes (rays prefer nematodes), whole loach or marine worms for fishing, red worms or artificially cultured live worms (such as breadworms and maggots), fresh shrimp slices, frozen fresh shrimp or Antarctic shrimp (it is best to sink to the bottom because

It is worth reminding that in the new rays, it is recommended to feed frozen bait when feeding. After getting familiar with it, pay special attention to the loach in the live bait. Misgurnus anguillicaudatus often rolls in the digestive tract of ray, causing it to be injured. When feeding the loach, it can be treated to a semi-coma state to prevent the physical injury caused by feeding the rays. However, due to the large amount and wide sources of live bait used in the growth process of rays, it may often carry germs. In order to prevent rays from being infected by live bait, it is best to process live bait. For example, high-concentration salt immersion, or even medicinal bath. As for the feeding frequency, it varies from once to seven or eight times according to the shape and feeding needs of the rays. In a word, ray is an edible fish, and once it is hungry for a long time, its state will produce great bad symptoms.

For freshwater rays that have just been fed, it is best to choose red worms as the initial food, and then feed nematodes or very small fresh fillets respectively. These foods are acceptable for most rays that can be fed. If these foods are small enough, they can be eaten inadvertently through the mouth and gills of rays, which gives rays a chance to try strange foods. Although these foods are mainly the food of very small freshwater rays, we call them "cup rays" or "pearl rays". The main foods of these bladder rays are insect larvae, shrimps, live shrimps and red worms. , can be regarded as a new ray meal.

Pay special attention when feeding: when the bait is not enough, the freshwater rays are easy to lose weight, but if they are fed too much, there will be bait residue, which will affect the water quality. Therefore, each feeding time is limited to a few minutes. If the rays are not fished within 10 minutes, the rest of the bait should be fished as soon as possible except the live bait.

Live bait: These so-called live baits include red worms or nematodes. They should be fed in moderation, but some can be left in the fish tank so that light can come in later. When cleaning the bottom sand, pay attention to whether there are any live bait residues in the fish tank that have not been eaten by the rays. If it remains in the bottom sand, it will lead to the production of nitrogen-containing organic matter in the radiation, which is one of the reasons why many people do not advocate putting bottom sand. Rays live in the bottom of the pond for a long time, and the residue in the bottom sand is easy to destroy the water quality because of insufficient filtration and filter ring equipment.

Feeding: Rays have a small mouth. Rays with a tail of 40 cm have a mouth width of only 2~3 cm, and the food size should be appropriate. If you see a ray swallow food, then spit it out quickly and suck it in, it usually means that the food we give is too big. Some species of rays, such as flower rays, have much smaller mouths than others. When freshwater rays train bait, it is best to use frozen bait as material first, but attention should be paid to the feeding rate and freshness of bait.

Sometimes, a well-adapted ray in the fish tank is getting thinner and thinner, despite the ample food supply. Most of these problems are caused by the fact that there may be no efficient food competitors in skates, or water quality problems and parasites.

Because freshwater rays eat a lot, there will be a lot of excrement, and it is easy to pollute and muddy the water quality of the fish tank, so it is necessary to change the water regularly for cleaning.

Train the rays to feed the bait by hand.

Some rays often can't find food, or they will go to the wrong place when feeding, and they can't find the food they just dropped. At this time, we can use "artificial feeding" to feed the rays. This so-called manual feeding does not mean feeding directly by hand (it is risky and it is best not to use hands). Usually freshwater rays have the habit of avoiding metal substances, which is obviously afraid of metal substances. So once we start asking for food, we will soon eat the food on the metal clip. We can use this habit to feed the rays and train them at the same time.

It is worth mentioning that when we feed Zhu, we can puncture or soak their fish fat in strong salt water, so that they lose their swimming ability. In this way, freshwater rays won't catch them because Zhu swims too fast!

When feeding Zhu, it is wise to add vitamin B 1 to the water in the fish tank. There is obvious evidence that Zhu has anti-vitamin B 1 enzymes in his body tissue, and these enzymes will destroy the intake of vitamin B 1. Therefore, it is necessary to add this vitamin to the skate fish tank. According to the expert's suggestion, the dosage is: add 50 ml of vitamin pills to 2000 liters of water and use it once every four weeks. The adding method can be to put the anchoring agent on the semi-dry sponge of the upper filter or directly throw it into the water of the fish tank. All the above methods are feasible.

Feeding frequency:

Amateur ray breeders believe that three times a week is enough for rays. Whether this statement is correct or not, at present, professionals feed them at least twice a day, usually three times. In this case, their rays will continue to feed. Therefore, the feeding frequency of freshwater rays must be sufficient. (Article source: Dragon Point Fish Neighborhood Encyclopedia)
