Causes and treatments of goldfish fin rot, and how many to keep at home for good feng shui?

Now many people like to keep goldfish at home or in the office. During the process of raising them, some situations are unavoidable. A friend asked: what causes fin rot in home-kept goldfish? How to treat it? Generally how many to keep for good feng shui? Let's take a look below.

1. What causes fin rot in goldfish?

When a goldfish's tail rots, it is generally because the keeper caused too great a temperature difference when changing the water, or because the water was not changed for a long time and the water quality deteriorated, or because the fish nipped and fought each other, injuring the tail. After being injured, the fish is susceptible to bacterial infection, usually mold, and mold causes saprolegniasis, so the tail begins to slowly grow moldy and rot. The general early symptoms are slow movement when swimming, reduced appetite or even refusal to eat. Then the tail begins to rot, usually with the connective tissue splitting open, taking on the look of a broken broom.

2. How to treat fin rot in goldfish?

The first thing to do is to isolate the goldfish and raise it separately to prevent other fish from becoming infected. Because fin rot is generally due to water quality problems, it is best to change the water first. But when changing the water, you cannot change it all at once, because changing it all at once creates too great a temperature difference that will only injure the fish more. Generally change one fifth of the water at a time. Then carry out thorough disinfection. If it is the early stage of the illness, you can add salt to increase the concentration of the water. But if the illness is very serious and the tail has already begun to rot, then medication should be used immediately. Generally potassium permanganate or copper sulfate solution can be used. During treatment, feeding live animal-based feed will help them recover faster, and more sunlight can also promote the fish's recovery.

1. The popular method. Everyone knows this method, and it is best to keep nine. Ancient scholars and writers liked to paint pictures of swimming fish, and they all titled them ”nine ru”. What are the nine ru? Ancient books record that the Book of Songs says: ”Heaven protects and establishes you, making all things prosper, like a hill, like a mound, like a ridge, like a hill, like a river just arriving, ever increasing. Like the constancy of the moon, like the rising of the sun, like the longevity of the southern mountain, never collapsing, like the luxuriance of pines and cypresses, all receiving their inheritance.” In this poem there are nine ”ru” characters in total, and all are auspicious words. Because ru and fish are homophones, many people paint nine fish and title it nine ru as an auspicious hanging picture. From the above it can be seen that the best number of fish to keep is nine. But if the fish tank is too small to keep as many as nine, then you can keep three or six, because three means “three threes without end” and six means ”six sixes without limit”.

2. Decide according to the five elements of the homeowner's life trigram, with the generating numbers being auspicious. Yijing numerology holds that: Heaven one generates water, Earth six completes it. Earth two generates fire, Heaven seven completes it. Heaven three generates wood, Earth eight completes it. Earth four generates metal, Heaven nine completes it. The generating number means adding members and prospering the family, and the completing number is the sign of prospering wealth and bringing in money.
