The Role of a Goldfish's Tail and Key Points on Keeping Goldfish

The goldfish is a very well-known ornamental fish, with a great many varieties, bulging eyes like two lanterns. The goldfish's body shape is very graceful, and it comes in many colors; keeping one in a fish tank at home can add a decorative touch to the home environment. The main producing areas for goldfish in China are the Beijing-Tianjin region, Fuzhou, Guangzhou and the Suzhou-Hangzhou region, and Fuzhou has the reputation of being the capital of goldfish. When you watch a goldfish swimming, you will notice that its big tail is constantly swaying, so what role does a goldfish's tail play? What are the key points of keeping methods?

1. What role does a goldfish's tail play?

Although a goldfish's tail looks very small and flat, it plays a very important role; the tail is like a ship's rudder, controlling direction, and is very flexible. When a goldfish swims, it also relies on the strength of its tail to provide forward momentum and keep its body balanced. During mating, the tail can beat the water waves so that the eggs are fully fertilized. In addition, the goldfish's tail can also attract male and female goldfish to each other.

2. What are the key points of goldfish keeping methods?

1. Choosing goldfish fry

There are many varieties of goldfish, and when buying fry you can choose a suitable variety according to your keeping needs. When selecting goldfish fry, try to choose fry with spread-out fins and a rather elongated body; this kind of goldfish fry has a larger skeleton and will grow larger later on. Of course, this also depends on the variety; for example, if the head growth is already well developed when it is still fry, it will be difficult for it to develop further later,

2. Rearing water volume

To successfully keep goldfish alive, you need a sufficiently large volume of water. If the goldfish's growing space is not spacious, the goldfish cannot fully open up and move around, there is no way to promote the goldfish's growth and metabolism, and it will be difficult for them to grow large. For home keeping, generally use a large fish tank to keep five to eight goldfish of the same variety; only in this way can they grow better.

3. High dissolved oxygen

Goldfish have a relatively large oxygen demand for growth. If they are kept long-term in water with insufficient oxygen, it will not only affect water quality and cause fish diseases, but also affect the goldfish's appetite, causing their growth rate to slow down. To keep goldfish well, you need to equip an air stone. Then also grow green algae, which can not only promote photosynthesis to produce oxygen, but also serve as a snack for the goldfish.

4. Feeding

The bait goldfish need is generally based on live food, and can be combined with some pellet feed. Live foods include bloodworms, fish worms, nematodes and so on. If they are small goldfish fry that have not yet started feeding, you can feed them some live water fleas. If it is not very convenient for you to feed them, you can choose frozen water fleas or red worms and put them in the tank.

5. Points to note

When keeping goldfish, you should change the water frequently, because fresh water quality can promote the goldfish's metabolism and keep them having a certain appetite. When changing the water, pay attention to the temperature difference; a difference of one or two degrees is fine, as this can promote the goldfish's appetite. But the temperature difference should not be too large, otherwise it will cause the goldfish to become ill or die.
