I regularly judge aquarium fish shows and get to see recent injuries of
aquarium fish (including rainbowfish) fairly frequently. Most wounds do NOT
show as pink areas, they show as skin colour which is the same as the
surrounding area but not as "shiny" as the missing scales, which are
usually transparent, are the only thing that is changed. For the underlying
tissue to be showing there has to be some scooping out of an area of skin
and this doesn't happen easily
Fish in an aquarium don't easily lose scales without a significant event
occurring
I am not a betting man but I really believe that if you consider that TB is
the most likely diagnosis then you are more likely to make the right moves
:-(
My understanding is that there needs to be a break in the skin for humans to
catch fish TB
