I’m in the last 16 days of a fallow period. I had set up a quarantine tank. Today I purchased my first set of fish. I purchased some captive bred clownfish and Benggai cardinal fish. They are in my quarantine tank. Do I need to treat. The lfs said they treat with cooper and being captive that I wouldn’t need to and should observe them. This is my first time with a quarantine system. Any advice would appreciated.
