First, look at the state: first stare at the fish tail and then look at the eye<\/strong>\u200c<\/span><\/h4>\n

\u200c1. Swimming test<\/strong>(Focus!)<\/span><\/p>\n

    \n
  • \u200chealthy fish<\/strong>Tail spreads naturally, cruises at an even pace, and turns nimbly with a tap on the tank wall.<\/span><\/li>\n
  • \u200cfish that have been eliminated<\/strong>: retracted fins on the bottom, head down and upside down, frequent rubbing against the pool wall (possible parasites)<\/span><\/li>\n<\/ul>\n

    \u200c2. Mandatory details<\/strong>\u200c<\/span><\/p>\n

      \n
    • \u200cfisheye<\/strong>: Clear and translucent without haze (haze = water poisoning)<\/span><\/li>\n
    • \u200cgills of fish<\/strong>: Lift gill covers to see bright red without defects (whitish\/ulcerated = gill disease)<\/span><\/li>\n
    • \u200crectum<\/strong>: Slight redness not prominent (redness = precursor to enteritis)<\/span><\/li>\n<\/ul>\n

      \"\"<\/p>\n

      \n

      \u200cSecond, look at the body type: head wide back thick tail shank thick<\/strong>\u200c<\/span><\/h4>\n

      \u200cGood Fish Criteria<\/strong>\"The longer you are, the more valuable you are.<\/span><\/p>\n

        \n
      • \u200chead<\/strong>: Broad, full forehead, rounded, not upturned mouth<\/span><\/li>\n
      • \u200cback (rear part of the torso)<\/strong>: Smooth transition from dorsal fin to caudal peduncle without depression<\/span><\/li>\n
      • \u200ctailstock<\/strong>: Thickness > 2cm (strong support, high disease resistance)<\/span><\/li>\n<\/ul>\n

        \u200cLightning case<\/strong>: Last year, I bought a \"big head doll\" koi on the cheap, with a big head and a thin body, and it was the first to turn its belly over during the wintering.<\/span><\/p>\n

        \"\"<\/p>\n

        \n

        \u200cThird, look at the scarlet quality: choose red as blood, abandon the orange like the setting sun<\/strong>\u200c<\/span><\/h4>\n

        \u200cthe science of colors<\/strong>(Red and white koi, for example)<\/span><\/p>\n

          \n
        • \u200cpurple silk floss<\/strong>: Positive red color with matte texture and sharp knife-like edges<\/span><\/li>\n
        • \u200csecondary scarlet<\/strong>: Orange-red with yellowish light, easily fading to pinkish-white over time<\/span><\/li>\n
        • \u200cdeadly color<\/strong>: Black gill covers, red spots with white spots (stress\/viral infection)<\/span><\/li>\n<\/ul>\n

          \u200cpractical skill<\/strong>: Shooting straight with a cell phone flash against the tank, the pedigreed scarlet disk is impervious to light.<\/span><\/p>\n

          \n

          \u200cFourth, look at the environment: the pool water is not as clear as the pool wall dirty<\/strong>\u200c<\/span><\/h4>\n

          \u200cSelection of fish pond subterfuge<\/strong>\u200c<\/span><\/p>\n

            \n
          • \u200cpreferred<\/strong>: Green moss hanging on the bottom of the pool, sporadic foam floating on the surface of the water (mature nitrification system)<\/span><\/li>\n
          • \u200cbuy with caution<\/strong>: Super clear water + pool walls painted snow white (new water irritates fish and makes them susceptible to disease)<\/span><\/li>\n
          • \u200cRun for it!<\/strong>: Pungent aroma wafting from fishponds (malachite green may have been used to disinfect)<\/span><\/li>\n<\/ul>\n
            \n

            \u200cFifth, look at the after-sales: dead fish package to be written into the contract<\/strong>\u200c<\/span><\/h4>\n

            \u200clesson learned through blood and tears<\/strong>\u200c<\/span><\/p>\n

              \n
            • \u200cthe essential three questions<\/strong>::<\/span>\n
                \n
              1. \"Has the food been off for the full 48 hours?\" (Transportation of spit-fed food tends to contaminate water quality)<\/span><\/li>\n
              2. \"Is it possible to video select the fish?\" (in case it doesn't fit)<\/span><\/li>\n
              3. \"How do you pay for casualties?\" \uff08\"The reliable merchants dare to promise 72-hour guarantee.)<\/span><\/li>\n<\/ol>\n<\/li>\n
              4. \u200cFocus on avoiding pitfalls<\/strong>: Online shopping to choose a fishery that can be picked up, express koi discount rate of more than 30%<\/span><\/li>\n<\/ul>\n
                \n

                \u200cthe principle of three non-corruptions<\/strong>\u200c<\/span><\/h4>\n
                  \n
                1. \u200cnot greedy for large amounts<\/strong>: Newbies buy 20-30cm subadults (highly adaptable, 1\/3 the price of adults)<\/span><\/li>\n
                2. \u200cnot greedy for more<\/strong>: Maximum of 3 fish from the same fishery (different batches of fish are susceptible to cross-contamination)<\/span><\/li>\n
                3. \u200cnot greedy for beauty<\/strong>: blue background, gold scale and other special colors with caution (mostly drugged)<\/span><\/li>\n<\/ol>\n
                  \n

                  \u200cLet's be honest.<\/strong>\u200c<\/span><\/h4>\n

                  \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Really good koi tend to be unassuming - a little wear and tear on the scales suggests a pond-raised, build-resistant fish, while those \"beauty contest winners\" with shiny scales in a glass tank may be discolored and sickly in a new environment. Remember, a fish that ignores you when you pick it out is usually tougher than one that chases you for food!<\/span><\/p>","protected":false},"excerpt":{"rendered":"
