Sorry for the loss, that was a pretty fish and one you were well attached to I hope the experts have some ideas. I've never even SEEN anything like that posted, much less having any clue!

That got out of control very quickly. In my experience PBT are beautiful but once they are afflicted with ANYTHING they go downhill very quickly. Sorry for the loss. Definitely keep an eye on the other fish in the DT.
