II. How do you keep small goldfish from dying?

1. Fry selection: what kind of fish are good to choose?

There are many varieties of small goldfish, so when selecting fry, try as much as possible to choose fish with a full body shape, symmetrical body and rich, vivid colors according to the characteristics of the variety, in order to increase the survival rate. Generally, it is best to choose 1, 6, 8 or 9 fish to keep. If you want to keep them together with other ornamental fish, you can pair six fish of other colors or six fish of the same color, which not only adds color to the fish tank but also does not affect luck.

2. Fish tank selection: what size tank is good to use?

Keeping goldfish is fairly particular, and many are placed at hallway entrances or in offices, so it is best to keep them in an aquarium of suitable volume. Generally, a fish tank with a water depth of about 20-25cm is best for raising fry, and when they grow into large fish, switch to a fish tank with a water depth of about 25-30cm. In addition, prepare a siphon tube, an oxygen pump and lighting equipment to provide a good growing environment for the fish. If there are many goldfish, you can buy a larger fish tank. Usually, a fish tank that can hold 100 liters of water can generally keep 3 fish of 10cm, or 8 fish of 5-6cm, so when keeping them, try as much as possible to choose a suitable fish tank according to the size and number of the goldfish.

3. Water quality requirements: what kind of water is good for keeping them?

Goldfish do not have high requirements for water quality. Generally, tap water that has been left standing for 2-3 days can be used to keep them and they can survive, but oxygen must be supplied well to prevent the goldfish from dying of oxygen deprivation. At the same time, change the water frequently to keep the water clear. Generally, change the water every three or four days in summer, once a week in spring and autumn, and once every half a month in winter. Each time, change only 1/3, and promptly remove excess bait and excrement from the fish tank to keep the water clear.

4. Water temperature requirements: what water temperature is good?

Small goldfish do not have high requirements for water temperature and can survive within a very wide temperature range. Generally, they can grow healthily at 20-28 degrees, but goldfish are also very sensitive to sudden changes in water temperature, so during keeping, try as much as possible to control the water temperature well. Generally, a deviation within 4 degrees is no problem.

5. Feed feeding: what do they eat?

Small goldfish have omnivorous feeding habits. Whether it is water fleas, earthworms, small shrimp, minced internal organs, bloodworms, or artificial feed, they all eat it, but they mainly eat meat-based food, so when feeding, try as much as possible to combine foods reasonably to ensure sufficient food, but do not overfeed. Try as much as possible to keep it to seven-tenths full, so that the small goldfish do not eat too much, which can cause indigestion and discomfort to the stomach and intestines.

III. How do you tell male and female goldfish apart?

Method 1. Look at the abdomen: the abdomen of male goldfish is relatively flat, while the belly of female goldfish is relatively bulging. However, this can only be seen when pregnant, so it is not very good for distinguishing them by this.

Method 2. Look at body shape: male goldfish have a slender body shape, while female goldfish have a short and fat body shape.

Method 3. Look at the tail: the tail of male goldfish is relatively wide and flat, while the tail of female goldfish is relatively thick.

Method 5. Look at color: male goldfish have relatively bright colors, while female goldfish do not have very bright colors.

Method 6. Look at the vent: the vent of male goldfish is narrow and long, while the vent of female goldfish is relatively large and round (can lay eggs).

Method 7. Look at the fins: the fins of male goldfish are relatively thick, while the fins of female goldfish are relatively short.
