What should you pay attention to when keeping koi at home?
When introducing koi, you must make preparations, which is of great significance to whether the koi can survive and quickly adapt to the environment of this pond:
1. Home fishkeeping When keeping fish at home, the cement pond must be soaked to remove alkalinity, change the water and age the water. When aging the water, it is best to add dense green water and cultivate it for a few days (the purpose is to accelerate the growth of moss) before fish can be kept.
2. Newly arrived koi have gone through transport, especially long-distance bumping, so the protective layer (mucus) on the fish body surface is easily scraped and damaged. Therefore, before the fish arrive home, you should prepare several tanks or large basins or a small fish pond at home, fill 1/2 of the pond (tank) with new water, and after the purchased fish arrive, first put them into the tank or basin or small pond, bathe them with 1%-2% salt water or 10—20 mg/L furazolidone or 5-10 mg/L potassium permanganate solution for 5—15 minutes (the time should be flexibly controlled according to the size of the fish), then put them into the rearing pond to rest quietly (if there is green water, it is best to mix a little into the pond), and add furazolidone powder to the rearing pond at a ratio of 2—3 mg/L, thereby reducing the incidence of fish disease. Never pour the water from the original plastic bag after long-distance transport directly into the rearing pond.
3. On the first day after entering the home, do not feed the koi; on the second day, do not feed or feed less. After that, the feeding amount should follow the principle of gradually increasing according to the koi's appetite. This helps the water quality avoid deteriorating and quickly turning green. Never overfeed at one time and cause the water quality to deteriorate. This will ruin a pond of new water and seriously affect the health of the koi.
4. All tools used for disinfection, including all fish-catching nets, fish basins, brushes, rags, suction pipes, etc., must be disinfected, sun-dried, and hung in a fixed and dry place. Do not throw them around. If conditions permit, in the koi pond or tank, an oxygen pump can be installed for the newly introduced koi pond to increase oxygen, so that the koi can quickly recover their strength after transport.
