How to raise red tailed goldfish

Generally speaking, the good quality of the food, the dragon like to eat, and the poor quality of the food will affect the feeding of the dragon, or even refuse to eat. The nutrient content of the diet also affects the feeding rate, especially the protein content, which has a great influence on the feeding rate.

How to raise the red tailed Golden Dragon?

Although the dragon fish is large in size, it can not give them everything to eat, and it is easy for the dragon fish to refuse to eat, so it is very important in feeding the dragon fish. It is a science to raise and feed the dragon fish. Xiaobian will tell you the common dragon fish feed and the precautions for feeding amount.

1、 Five kinds of common longfish feed

1. Insects

There are many kinds of insects, such as locusts, cockroaches, crickets, and so on. The basic birds can eat the insects, dragons and fishes. The insect is small and easy to catch when floating in the water. The disadvantage is that insects generally have shells, wings and other parts that are not easy to digest, which may cause damage to the intestines and anus of dragon fish.

2. Fish and shrimp

Including shrimp, small fish, loach, frog, tadpole, etc. These diets are very helpful for body strength and hair color. It is recommended that this kind of food be the main food for dragon fish. At the same time, we should also pay attention to the fish and shrimp food is also the source of fish infectious diseases, and do a good job in the inspection before feeding.

3, meat

This kind of food includes shrimp meat, pork, etc. it can be cut into small pieces when feeding, which is easy for the dragon fish to swallow. However, this kind of food is not suitable for the digestive system of the dragon fish, and long-term feeding may cause the dragon fish indigestion.

4, particle

Mainly refers to the fish grain bought on the market. This kind of food is rich in nutrition, but the dragon fish often don't like to eat, and only after training can they start eating.

5. Small reptile

For example, centipede, gecko, etc. this kind of food is one of the favorite foods for dragon fish. However, this kind of food is expensive and hard to find.

2、 Four factors influencing the feeding amount of longfish

1. Specification (size) of dragon fish.

In the larval stage, the growth speed of dragon fish is very fast, and the requirement of nutrition is also very high. The growth rate decreases with the increase of age, so does the demand for nutrition.

Therefore, compared with the half adult stage, the growth rate of young fish is faster when they are fed the same amount of feed, the daily intake can account for more than 50% of their body weight, and the feeding rate is higher. For example: 0.015 grams per day, the daily intake of juvenile dragon fish can reach 54% of the body weight; 100 grams per day, the daily intake of juvenile dragon fish is only 5% of the body weight; and more than 1000 grams of dragon fish, the daily intake only accounts for 1% of the body weight.

2. Water temperature.

Fish are all thermophilic animals, and dragonfish is no exception. With the change of temperature, it directly affects the metabolism speed and appetite of dragonfish. In the temperature range of 23 ℃ to 30 ℃, the feeding amount of longfish increased with the increase of temperature.

For example, the feeding rate of 50-100g longfish is 2.4% at 15 ℃, 3.5% at 20 ℃, 4.9% at 25 ℃, and 6.8% at 30 ℃. Therefore, the feeding rate should be determined according to different temperatures, specifically reflected in the change of feeding rate in different months of the year.

3. Water quality factors.

The quality of water quality directly affects the appetite, metabolism and health of longfish. The oxygen content in water is a direct factor affecting appetite. We can increase the air volume appropriately before and after feeding. Before feeding, the oxygen content is high, the appetite is strong, and after eating, the oxygen content is high, which is helpful for the digestion and absorption of the dragon fish. Therefore, we should adjust the feeding amount according to the content of dissolved oxygen in the water to reduce the deterioration of the water quality caused by the surplus bait.

4. Feed factors.

Generally speaking, the good quality of the food, the dragon like to eat, and the poor quality of the food will affect the feeding of the dragon, or even refuse to eat. The nutrient content of the diet also affects the feeding rate, especially the protein content, which has a great influence on the feeding rate.
