I talked to an experienced reefer today who told me that he does not quarantine any fish before putting them in but instead adds herbtana as a preventative measure.
Its interesting how everyone has their own methods to treat and prevent illness.
The method I think im going to use is as follows; dose herbtana when fish are added as a precaution or when signs of sickness are shown, and any fish with more severe symptoms will be quarantined and treated accordingly to bring them back up to heath. If my tank was bigger and more costly I would not hesitate to quarantine everything.
On a good note it looks like my clown no longer has ich, just a secondary bacterial infection.
Im not going to post any pictures tonight but im positive its ich. The bumps on the engineer goby are qute large and pronounced.
