All I can say about the blue tang is that she's not dead, it's so hard to tell when they're stressed. BTW, after the fwd I've found that the the yellow tang also has flukes. I wish I had a larger tank but I entered into this whole debacle understanding that it may cost me some money to save a life or two. I currently have one blue tang in a 55 gallon tank that's piped to a common 20 gallon sump with a 32 gallon biocube. I have a deep sand bed in my refugium and don't have any issue with nitrates as of now. In the 10 minutes it took me to decide if I should try to save these guys I pictured taking them to my lfs if they recovered. For a new problem; is it a bad idea to add them to my dt with my current blue tang or could she possibly kill them until I can find them a new home? Would it be best to keep them in the qt tanks?
