I have a relatively new 55 gal reef aquarium. It is stocked with soft and hard corals, live sand, 3 wrasses, 1 stoplight parrotfish and 1 honey damsel, all collected in local waters. I recently added a redlip blenny and yellowtail damsel and they quickly got ICH. So I ordered Chem-Marin Stop Parasite, but it did no good and the two new fish died, but the existing fish showed no signs of Ich . I then purchased a 9w double helix uv sterilizer which I run 24 hrs per day.This weekend I introduced a French Angel and it was doing great for the first two days, now it has Ich and/or Oodinium. But the other fish are still doing great. Why do the existing fish not get parasites but new fish quickly do and then die???? I also add Marc Weiss Reef Vital DNA at triple dose for three days after adding the new fish.
