    So we know that a stressed fish is more likely to acquire a disease, as it lowers its immune system. It is highly likely that a stressed fish will contract whitespot. In the following scenario is there a chance that the fish could still be infected?

    OK, so you've quarantined that Powder Blue that you've always wanted. First bucket method, then in a QT tank for a few weeks. Feeding it garlic enriched food and keeping it in a system with UV. Do one more bucket method and then add it to your display tank.

    This is the first fish in your tank which completed its cycle 6 weeks ago, so there is no disease in your tank.

    As you move it to your display you weren't careful enough. The fish starts thashing around and falls onto the floor. You quickly scoop him back up and pop him into your display.

    The poor fish is now as stressed as you get. Is there a possibility of him now contracting Ich?

    I don't think there is such a thing as a disease free tank

    Even if it is brand new and has been empty for a while? Wouldn't there be no host for the disease?

    The first question is easy to answer. If the parasite is not present in any instant then it is not possable for any contraction.

    So no matter how stressed a fish is. Contraction is not possable if the parasite is excluded from the the environment.

    Thanks.
    I read somewhere that Ich can only survive in temperatures between 15-30 degrees celcius. Is that true?
    If so, could we just put the fish in a QT with water above 30degrees?
    And if you run a FO system you could raise the temp in your DT as well, as there will be no corals that it will affect?

    That sound like freshwater ich. I remeber back then i bump up my temp with my bathwater system and few days later no spots...

    With marines that does not work, fresh water ich and marine ich is not the same thing. Loads of newbies, even seasoned reefers buy things for ich and 99% of the time its made for freshwater ich and because its save to use in marines they say its for marines also...

    Thats a first time a see a article talking about temp with marine ich... Would like to test this... I always read about raising temp with freshwater ich.

    They not saying in that article that raising your temp above 30deg will kill it?

    It day that it affects marine fish living between 15 and 30 degrees so I would assume so. Unless this is a load of BS.

    Quote from advanced Aquariust and confirmed in many papers.

    "temperature manipulation or raising the temperature to 86F is a treatment that has been used with some success against freshwater ick Ichthyophthirius multifiliis. However, the optimal temperature for the reproduction of Cryptocaryon irritans is 86F so raising the temperature to this level will not kill this parasite (Noga, 2000).Raising the water temperature to a lesser degree has also been suggested as a means of speeding up the life cycle of Cryptocaryon irritans. While it is true that the life cycle of this parasite is temperature dependant, speeding up the life cycle may not be helpful to the fish. Raising the temperature can change the blood pH causing further stress to fish already weakened by disease (Bartelme, 2000a. McDonald & Milligan, 1992). If the water temperature was not too low to begin with, then it may be better not to adjust this parameter. If the temperature is adjusted, any change should be small and take place slowly."

    If you read the article you posted they do not mention temp as a means of control.

    SA has a very reputable Aquariust on marine diseases. One we should seek to get on our guru panel. :whistling:
    @David Vaughan he has produced many papers and presentations world wide.

    Look him up. :)

    Shot. Have you approached him? @Nemos Janitor. Could you please update your thread on the gurus reasoning.
