Yes, pre-quarantined would be a good choice. It probably always is. What really hurts, other than watching a creature suffer for my arrogance and stupidity is that I always preach to be patient and then I turn around and act impatiently and imprudently. The old 'do as I say, not as I do' routine.Sorry to hear about the CBB. I think if I ever try to keep one it will be of the pre-quarantined variety. I'm willing to pay more to make sure that particular fish would be healthy and eating. We've all put things in our tanks that we know we maybe should have waited on though, it stings but all you can do is learn from it and do it differently next time.
