New fish that I have eating (actually 2 of them). I had an observation tank mechanical failure that almost killed both (bacterial bloom - - -> low oxygen). Now I'm seeing little dots on the larger of the two Filefish. They are very small and fine. More dust like than salt or sugar crystals. Observation tank is a very mature 15 gal tank that is in lock step with my display tank. As thes fish are very picky eaters, I'm thinking of using the Tank Transfer Method of treatment. I'm feeling copper will end up killing them through starvation. I'm not convinced this is Ich though.
Thoughts?
