I think I may start a thread asking if anyone has successfully QT'd a possum wrasse - although I may have already done this a month or two ago when I first noticed. As I stated earlier I feel like the only way it could work would be to waste a lot of pod bottles and liverock to meds. I imagine once my tank makes it to the month 1 year + mark (in a few months) I should start seeing less scratching periods?
