Did some searches on MV and here is what I found....
Marine Velvet or Coral Fish Disease (Amyloodinium ocellatum) is an algal protozoan belonging to a group of single-celled organisms known as the dinoflagellates. This dinoflagellate is related to the dinoflagellate that causes Red Tides. In severe cases, tanks can be wiped out in as little as 48 hours. The life cycle of Marine Velvet is about 6 to 12 days depending on the condition of the water (The warmer the water the shorter the life cycle). Marine Velvet starts off in a free-swimming stage before it attaches to a host fish. Once it is attached to the fish it feeds for several days. Once it is fully mature, they fall off and continue to grow in the substrate. One dinoflagellate can multiply and produce as many as 250 more dinoflagellates.
Symptoms -

I did notice my domino having what appeared to me as cloudy eyes, and yesterday stated rubbing against stuff, but that is the only symptoms I noticed. I hope i can get the tang & the MB & the yellow tail out int the QT tank, but I tried to catch them several times before with no luch whatsoever. They have an enormous amount of hiding areas and as long as the net is in the water you will never see them. I have 300lbs + of rock in there!
