I've just set up a new aquarium for not too long. I just noticed a fish been scratching its body aginst the leaves/wood for abit. I'm suspecting ich at work :shake: 1-2 fish may have 1 white-spot on them but it's difficult to tell at this point. What's the best way to treat ich? does the ich med generatlly kill the beneficial bacteria as well? Need to remove the carbon from the filter when applying med? I'm thinking about quarantining the suspected fish, but i don't have any other tank setup for this. Thanks
