Hi folks!
Like the title says, are white spots the only indication that a fish has Ich? The reason I ask is if they are and a fish shows no visible signs of ich (white spots) and Ich needs a host to survive, wouldn't it be safe to say that the tank is free of Ich? If you do not introduce any new fish into the tank and after a period of time, a fish develops ich, where did it come from If it needed a host to survive in the first place?
Or are the white spots just the final..or visible... indication that the fish has ich?
(I hope this makes sense)
