I made the cardinal mistake of putting a fish straight to my display tank. :debi: I have talked with a few people on here to help me through what was wrong with my heniochus butterfly fish but, it had passed after what seems to be marine ich. I have read some things on here about treating your display tank but I just want to make sure I am getting this right. I am ok with letting my tank sit fishless for 8-10 weeks from what I read. Do I need to do any water changes? Drop the salinity? Do anyting to the live rock thats in the tank? Raise the temp? I am perfectly ok with letting set empty for this to "cure". I know I tried to cut out the quaratine tank step but will not do that again. Any help getting on the right track would be appreciated.
