Well, the fish died today. I'm quite sad about it really as I was very fond of this one and I've spent a lot of time, energy and money trying to make her better. Daily 50% PWC, meds, followup on her behavior...etc. Its a shame. She was full of energy one minute, behaving normal, then poof!
Thanks for the support and info shared by all on the forum.
cheers
