Yea, it's really hard to say. It's my long running theorm that about 99% of the Ich and Marine Velvet in customers tanks, came from a fish that got infected in either a wholesaler, distributor, or at the retail level. If you were able to get fish straight from a collector, Ich and Marine Velvet would be non-existant in this hobby.
The only thing we really can't provide for our fish, is clean, fresh, water. When a tang or Tusk or other fish gets Ich in the wild, that bit of Ich drops off dutring it's life cycle at a location in the ocean. The fish still continues to swim and after all the Ich has dropped off, he is no longer affected. This is actually the 3rd form of treat for Ich. You had 2 tanks, and constantly switch the fish back from one tank to the other. After you move the fish, you completely drain and sterilize the other tank. The Ich drops off the fish and is killing when you clean the tank. For obviously reasons, it's almost impossbile to actually carry out this method.
Other things like internal parasites, flukes, and isopods, yea, almost exclusively come from the wild.
If you are being serious,
, a FW dip only kills a portion of Marine Velvet or Ich on an infected fish. Many of the parasite are deep within the fish.
A UV sterilizer is virutally useless to fight Ich or MV.
I'm kidding.
