So I've been treating both Midas and Rhett for fin rot and they seemed to be making some progress, and I had changed out the water in the 10 gal today and completely cleaned it out, but apparently the dividers weren't in place tight enough, and when I came home from class tonight they were on opposite sides of the divider!!
Then I take a closer look while freaking out and see that both have HUGE chunks of their caudal fins!!
I was so hopeful that they were getting better. Now I just feel like an idiot, and I'm so upset!!
