Sorry to see - but my concern is that this fish didn't die from ich, something else happened to it. The picture from this morning showed a mild case. A fish like that should have had days before succumbing to that parasite.Well guys I appreciate all the advice and im still going to go forward with getting all the fish into a quarantine system to get treated with copper. Sadly my little guy was gone when I got home from work today. I really appreciate all the advice and im going to take this as a learning lesson and change things up as I go forward and introduce fish into my tanks.
I've seen ich combined with velvet - the fish show just a few spots, but they breath really fast and then they die.
Another really common issue is cyanide poisoning. These little blue tangs live in heads of Acropora coral. The only way to catch them in commercial numbers is to either break up the whole head of coral, or squirt cyanide into the coral head to drive them out. The trouble is, about 40% of those fish end up dying a few weeks after collection.
