So basically over the past two days I lost both my fish one to ich and the other died for unknown reasons. Basically I'm going to completely re-do my entire tank. I don't mind re-doing it cause it's such a small tank but I want to re-do it because I heard ich doesn't leave the tank unless you qt the tank for 8 weeks. Rather than do that I'm going to just change the filter/bio wheel and clean everything very well. I will put putting new water and sand as well. I have a live rock though and a few blue leg crabs that I want to keep alive in another tank while this one re-cycles. Will the crabs and snail carry over the ich disease (on their shell or anything). I will also hope to keep the one live rock I have alive in the spare tank as well. I was also wondering if the live rock will hold any of the ich disease either. Please let me know. Thanks.
