This article is your go-to guide for treating Koi fish with white spots and blood lines, complete with a rundown of effective medications and tips for prevention and daily care.

Unveiling the Mystery: Causes and Identification of White Spot Disease

White spot disease, or Ichthyophthirius multifiliis, is the culprit behind those pesky white spots. It's like a tiny, invisible party crasher that invades your Koi's skin, especially in the blood vessels. You'll notice these spots more in areas with lighter colors. Your Koi might start acting like a tiny whirlwind, frantically rubbing against objects to scratch the relentless itching. Spot the symptoms, and it's time to spring into action!

Medications That Can Save the Day

1. Malachite Green: The Old Standby This is a classic in the treatment arsenal. It's like a tiny bomb that explodes the cell structure of the tiny parasites. Just make sure to follow the instructions, dilute it properly, and keep an eye on the oxygen levels—it can be a bit of a hog. 2. Chlorine Dioxide: The Gentle Giant A safe, non-antibiotic disinfectant that's like a knight in shining armor for your pond. It's great for daily maintenance and wiping out those pesky parasites. Just don't overdo it; too much can be a bad thing. 3. Mercuric Nitrate: The Heavy Hitter This one's like a sledgehammer. It's powerful, but it's also like a loaded gun—it can be dangerous if not handled properly. Wear your protective gear, and be careful not to mix it with other medications. 4. Temperature Regulation: The Warm Welcome Sometimes, a little heat can be just the ticket. Crank up the temperature to 28-30 degrees Celsius and keep it there for a week. It's like throwing a party for the parasites, but they don't know the party's over until it's too late.
