So I got 2 clownfish (1st fish to add to tank) and I did not quarantine as they are my first fish to add. What could happen? Ich happened! So my question is what is safe to use for ich if you have corals? I have several zoas/palys, 3 acan lords and 1 acan echinata, 1 mushroom, and 1 duncan. I read that copper based treatments are a definite no. Any advice on best treatment options? Other than setup a QT for future fish?
