Regarding
Herbtana
Please remember Herbtana is a "
herbal, immune-enhancing stimulant"
It does not treat Whitespot or any other disease.
It only helps with boosting the natural immune system of the fish.
If the outbreak is not major, it might help, as it did work for some people.
I for 1 agree with Jaco that if the fish is not in very bad shape, do NOT catch him and try and RO dip him etc, as that will only stress him out more and has a negative effect on his immune system.
Even copper treatment has a negative effect on healthy fish.
Whether WS is always present in the tank, biologists still seem to disagree on that.
I lost a Regal and a Bi-color Blennie yesterday due to WS. But because my WS strain had a look somehow similar to that of Velvet, and the strain was physically very small, Herbtana did not work for me. I treated my 1 clown and Scopas with RO dips, once daily. and according to David Vaughan from Two Oceans Aquarium it should be done only ONCE a day, and not for more than 5 minutes.
