Apologies for cross posting - I'm in the UK so appreciate info from both
sides of the pond.

What would you recommend to treat minor injuries, scrapes etc? I have loads
of different water treatments but sometimes it seems more stressful to
isolate a fish that's only got a minor wound. I'd like to find something
that can just be dabbed on the fish and then return it to the main tank but
everything (at least here in the UK) seems to just treat the water
