Hi all,so since Saturday I've lost 8 fish to either velvet or ick,not sure which one,tank is up and running for 6 months,innovative marine 100 ext,beautiful tank,was so disgusted I was going to tear down and well but thought twice when I watched a beautiful rainbow rbta and a weeping willow(the only corals in there at the moment), and various snails and hermits apparently unaffected by the disease,my question,do these diseases affect corals and snails etc?,really don't want to shut down and for now would be quiet happy just to have a coral reef without fish for a while until the disease dies off ,would really appreciate any advice.
