ich is not a disease. It is a tiny microscopic critter that swims through the water :lol:
Why do mosquitos bite some people and not others?......why do some people swell up and are itchy for days after being bitten by a mosquito but others aren't?.....why would you have 11 people in a bathroom?!?!

smart snakes??

As Marie stated, ich isn't a disease, it's a parasite. It's like 10 people going for a hike in the swamp. Not all will find a friendly leech, but some will. Nothing to do with immune system or stress. It's a parasite.

It doesn't matter what it is. It's the method of transmission.

Air is to humans as water is to fish.

Virus is to humans as parasite is to fish.

If a deadly virus is in the air all humans around it will be effected.

If a parasite is in the water all fish should be effected.

But they're not, because healthy fish can resist and fight the effects of ich

You're still making stuff up to cover up for the other stuff you made up. Virii are not comparable to parasites in any form or fashion. Just not

I feel so sorry for you, Marie. You and aquattro's tank got ich just one after the other, it's terrible. It looks like people got this problem around this time of a year and into the spring.

It's true that some fish won't be dead because of ich infection. But that doesn't mean we are not going to do anything to prevent the infection. Ich can be eliminated from a tank if you know its life cycle. A fish can have ich and survive this time, but maybe not next time.
And I don't buy the theory that a fish can have immune to ich. Ich is not a virus or bacteria. it's a parasite and it can attach to anything it get in contact with.

Lol we'll go with your non made up theory that ich parasites are smart and only attack the fish they dislike most

A healthy fish has a slim coat over its scales and in its gills. Which keeps ich from attaching itself.

Stressed fish lose the slim coat and are more Likely to be effected by ich

Actually Casey8, Aquattro's fish has Marine Velvet...... much more serious problem then Ich. Ich really is like fleas and at least in my mind, not usually fatal unless there are other things going on to weaken the fish

Actually, I said snakes "may" be smart. Not ich.
