I have a brown ghost knife (Apteronotus) who's getting worse and worse ich every day. I had treated the tank he's in with Clout (Aquarium Products), which got rid of it for the little blackbelt cichlid (who was the fisrt to show symptoms), but it looks like the knife and a small pleco are just getting worse. Any ideas? I was thinking malachite green might help, I've used that on aros and on a glass knife and it seemed to work well, but I hate to stress him out more with another treatment. Thanks for any advice,
Mike
