I have a community tank, that seems to have a fungus or similar infection, (fish scraping and a barb with a 1/16" gray patch).

I have heard that Loricariidae have a low tolerance for copper.

Is this true, and what other medication ingrediants should I avoid?

Pima fix and Mela fix are the best bacterial and fungal medications to use on delicate fish. They also will not harm plants or invertebrates. They are made of all natural plant extracts. I recomend these for any fish.
