I am wondering what the consensus is for my fish. I've had them well over a year and haven't added anything new in at least 6 months, probably longer than that (last thing was a frag of coral). I've read before that ick will die out on its own after 11 months if one has not added anything new (I'm assuming genetic inbreeding causes sterility after a time). Is this true for other parasites that might have come with the original fish? I am on the fence about adding some of that well-seeded rock to another, newer system to boost pod population. This could be considered an extended observation quarantine. Some reefers observe only and if nothing appears within a set time, the fish are introduced to the display. The fish are 2 skunks and a tail spot blenny, all fat and eating daily. Everyone also recent went through a move to another house 6 months ago and if anything would have caused stress (and a disease) to appear, I figure that would have been it. The newer system contains some of my other clowns, obtained directly from a breeder, and I know they are pest free. Just wondering if I'm worried about nothing or should I go about letting the rock with pods go fallow.
