Ich in DT

[FishingGoalie]

I agree with brad as well. Almost every tank has ich in it, some strands may be worse then others. I know i have ich in my tank but if everything is happy and healthy no one shows any signs of it. If i change a tonne or if for some wacked reason my salinity changes my sensitive fish like my regal tang and blue throat trigger will show signs almost instantly so i quickly find out whats wrong and fix it and within 3 hours all signs of ich are gone.

And are you sure it was ich? both wrasses and fire fish sleep in the sand so it could have been sand on them?
