The Tangs had a bit of Ich when I picked them up.

I originally thought, "Blah, just a tiny bit of Ich, no big deal, been there done that"

I fed them garlic and selcon soaked Mysis and countless sheets of nori, they were all eating, so I thought they'd be fine.

The Ich was receeding, or so I thought it was, but the next wave was much worse than the first. I am thinking that it may not have been the first cycle of Ich that these Tangs had. But as time passed, it only got worse and worse, until virtually every fish in the tank had Ich, and then the dying started.

Long story short, don't rush to pick up newly shipped fish, let them settle down for at least a couple of weeks.
