You just made that up.....

Ich is all over the place in the ocean. If it was to be killing healthy fish, they'd all be dead

Just like healthy people with normal immune systems don't die from the common cold

Fish in the ocean have a vast area in which to swim, not contained in a small box with a pathogen population explosion..
Good theory, as far as theories go, but unless you have something to back that up, you made it up...

I would have to agree. I know that my tank has ich but I have seen absolutely no sign of it what so ever in over a year. The only time I ever see it is when I add a new fish to the tank and then my powder blue and purple tangs have a break out for a few weeks.

I made it up based on personal experience. And I'm not the only one that has this opinion.

If ich attacks healthy non stressed fish, then wouldn't all fish in a tank be effected at the same time?

What exactly do you think ich is :lol:
Ich IS a parasite......like fleas. Fleas are everywhere too but not every dog has fleas.
My dogs (and house)do not have fleas but if I found a carpet at the second hand store and brought it home without cleaning it properly there is a chance my dog will get fleas.

Ich is NOT a virus, it has no similarities to the common cold what so ever

Think of it this way. Marko lives on the planet. Venomous snakes live on the planet. Marko can probably avoid these snakes for most of his life, just going about his business. But...should we lock Marko in the bathroom, and then dump a bucket of venomous snakes in with him, well, Marko's gonna be dead.

I am so sorry to hear that Marie. please keep us updated on how he does. I did recently gone through the same with my show achilles, unfortunately my guy didn't make it. Now I have a 4 inch spicement which also contracted ick. I am gonna try uv and protomarin and hope for the best. I guess best of luck for both of us.

The way I see it is if there's and airborne diesease that kills normally healthy people. The entire world population would die fairly quickly.

I've see lots of fish survive ich untreated. I've never heard of a human surviving venomous snake bites untreated

And if you had 10 other people in the same bathroom. Why would the snakes only attack one person?

Oh this is classic! :lol:

Also true...Can't compare a closed system to the ocean.
