Ok, new day - new problems. I finished the kanaplex, and administered the last dose of metro on Saturday. Did a 15g water change yesterday as the alert badge was reading .05 again.
The first day without antibiotics, yesterday, the flame wrasse started to get these white marks again. He had them in the DT, I had assumed were related to ammonia after his first QT ammonia-spike incident (see my other thread for reference) The white marks had stayed while he was in the display, and disappeared after his rally bath and have been gone until now. They are very, very faint - hard to get on camera. They are still there today.
Also, the reason I was treating with kanaplex originally was that both the fairy wrasses had a couple marks on their fins. Today, the rhomboid has a HUGE chunk out of it's tail. I mean, it looks bad.
My kole tang could be to blame...he chases everyone else in the tank. But none of the other fish have ever had nips or injuries - just the rhomboid. This is the third time, and definitely the worst.
So my questions...could both of these things - the white marks on the flame and the rhomboid's tail- possibly be some sort of stubborn bacterial infection? It's just weird that they both came back right after the antibiotics stopped and had been present on both fish previously. I was starting to think maybe brook with the white marks on the flame, but they have had a rally bath and full treatment of metroplex so that's not likely.
It could also just be nipping/ammonia. But, the ammonia has not been over .05 (I've been watching like a hawk) and I haven't observed the tang picking on the rhomboid more than any other fish and none of the others have been nipped.
I'm on the fence about starting another round of antibiotics. Maybe furan-2?
What do you think?

I'll try to get some pictures, but the marks on the flame don't show well on camera. It's almost like the scales are turning white/hazy.
