Yeah, was the newer of the two. She got through QT without incident, and never lost a bit of her appetite with prazi or cupramine (as I've experienced when treating many other fish). She was in the pool for several weeks with no signs or symptoms that something could be amiss. As much as I hate losing fish to something within my control, losing one to some unknown factor IMO is worse, as there is little to be learned from, and ultimately corrected in the future. But yes, I agree, mysterious losses do happen from time to time in spite of our best efforts to ensure otherwise.
Sorry for the loss of the queen. They are definitely beautiful fish and losing any fish to unknown reason sucks more IMHO. On a lighter note, might be a reason to set up a an autopsy area, haha. :lol2:
