Fish dying Help

[Branespikin]

Hi Guys,
Last week my Blotchy died today one of my clowns is dead. The other is breathing heavy and looks like white fuzz in him. I have a hawkfish and carpenter wrasse whi still look ok. I did not QT nor do i have a QT tank. Anyone know what i should do. Anyone want them to try and save them?

From your description, it maybe marine velvet. It's difficult to treat. I would try to move the remaining fish to a separate tank.
