  • Stress & Disease: Key Points, Tips & Tricks

    1. Probably 80-90% of diseases in captive fish can be prevented by avoiding stress.
    2. Diseases and pathogens are almost always present in tanks, but a healthy fish's immune system will prevent them from being a problem.
    3. Sick or Diseased fish should be isolated whenever possible. You do not want to spread infections among other healthy fish. (IE Hospital Tank)
    4. There are literally hundreds of afflictions that can effect the health of your fish. The most common are discussed below.

    Things you need to know.

    1. Don't buy or add fish to your established tank that have any sort of the following symptoms:
      • Don't buy fish from a tank with alot of dead fish in it. Most likely they have a disease.
      • Any white mucus or Salt-like specks. (20-40% of all pet stores have diseased fish, be careful when buying new ones)
      • Unusual swimming behaviour e.g. tailspin, rapid or jerky movement
      • Signs of injuries to fins and body. e.g. bleeding, ulcers, skin or fin tear
    2. Pay attention to the fishes for at least a few minutes a day. Look for any of the following signs:

      Bad signs:

      1. The fish is scratching against tank decorations, rocks or sides of the tank.
      2. There are visible spots, lesions, lumps, or white patches on the fish's body or fins.
      3. The fish's tail or fins appear frayed at the edges or are breaking off, disappeared.
      4. Red streaks near scales.
      5. The fish gasps at the surface of the water.
      6. Gills that are puffy or swollen and the gill tissue is bright red or even a grayish color.
      7. Clamped fins
      8. Fish suddenly becomes really fat.
      9. The fish refuses its usual food for more than 2 days. The fish floats, sinks, whirls, or swims sideways.
      10. A normally active fish is still.
      11. A normally still fish is very active.
