How to raise koi fish?

1. Fish species selection: Fish species with healthy body, no trauma, no desquamation and other diseases, bright body color, various colors and clear boundaries should be selected. Color is the most intuitive embodiment of koi fish. When choosing, those bright, gorgeous, clear stripes, neat edges and dazzling are the top grades. As for stripes, you can choose according to your personal preference.

2. Feeding density: Please refer to the koi fish density table for stocking fish ponds in general. Generally, the density of water cluster boxes is 60 cm× 30 cm× 15 cm, 15 cm ~ 20 cm in koi fish, 8 in 90 cm× 30 cm× 50 cm,10 cm×.

3. Feeding bait: koi fish is an omnivorous fish, so it is best to feed synthetic granules, bait, bean cakes, vegetable cakes, bread crumbs, fish worms, clams, crab meat, duckweed, etc. It is best to feed the fish regularly to avoid the stress reaction of the fish.

Attention to aquaculture in koi fish:

1. Don't put koi fish into the new tank too quickly.

Even if the best nitrifying bacteria are used, koi fish will not be released until the third day, and premature release of koi fish will only do harm rather than good.

2. Don't overeat.

Feed the right amount, just eight points full, usually only once a day, more than twice is not good. Because novices haven't fully mastered the water quality, and haven't figured out the influence of excreta and food residues on the water quality, it is enough to feed them once a day, and don't feed too much. Don't overfeed the fish, lest koi fish have enough to eat. The probability of starving fish in koi fish is too low.

Step 3: Filter.

Under the condition of good filtration, it is very important for the filter to run continuously without too frequent flushing. Nitrifying bacteria population on filter media is a great guarantee to ensure the health of koi fish. If the filter material is completely replaced or cleaned too cleanly, the digestive flora will be washed away and its due function will not be achieved.

Usually, the time for changing water and cleaning filter materials is separated, and the filter materials are washed in batches or just casually. If koi fish has problems after cleaning the filter, stop feeding immediately for two to three days and add nitrifying bacteria immediately.
