Hey Jason,
This is a late reply
but flashing is when a fish scrapes its body against glass, decor, or substrate because something is attacking its slime coat, scales, or gills.
Anyway, the reason I am updating this thread is because I finally added my Tiger Barbs to my display tank!
No pics because, unfortunately, my tank has a horrid case of Green Dust Algae on the glass. Once I get it taken care of, I'll post a FTS
My fish are still flashing a little bit, but melafix + pimafix seems to take care of it, so I will continue to dose them. I went ahead and added the TBs because I cross-contaminated my QT by using the same python... so it's actually less medication to treat only the main tank.
This is the first time I have thoroughly planned and stocked a tank to completion. Before, I had a nasty crash and burn from disease and aggression. Thank you all for teaching me so much, answering my questions, and following along as I built this tank!
The fish are getting along great.
