White spots but not "white spot"
My two German Blue Rams have white spots on fins and tail.
I first thought it was "white spot" and used interpet 6 to treat in the past so used it again.
It hasn't cured them. Furthermore I have two clown loaches amongst other fish and no other fish have symptoms and I'm sure if I had white spot in my tank, other fish (especially the clown loaches) would have it too.
Any ideas what it could be?
