How do fish get ick?

9/10 from other fish.

If the water is to cold, from other fish, and from stress.

 

[ar0wan]

it's like the common cold to humans
normally their immune system keeps it at bay

cold water + stress + exposure to new fish = ICH

What confuses me about this is people say if you keep water conditions good you won't get ICK, but all fishes have it. So if you add in a fish with ick into a tank with good conditions, how does it spread?

 

[ar0wan]

keeping the water warm is your primary defense

the ich jumps on the fish and goes for a ride



stress
water conditions
and new inhabitants and so forth



answering shua71- i believe that having a new fish introduced will stress others somewhat. also fish aren't really immune to ich it just attachs on ( i believe) you gotta remember i'm not no ich-xpert

Bad water quality, stress, new fish etc.

Well what I'm confused about is that i've heard all fish have ick, it just takes bad conditions to activate them. But if you introduce a new fish with ick into an aquarium with good conditions, why does it pass onto other fishes?

I guess just because it's contagious? And then when there is bad water and stess they get sick.
