Long story short, I just completed a total breakdown of my tank, bleached everything, euthanized several fish, and got it all put back together, after an ongoing struggle with columnaris. Just tonight, my healthy fish went back in. I carefully inspected each one to make sure there looked healthy. Apparently not good enough. 3 of my 5 clown loaches have what look like noses on them. I can't remember if it's normal! I'm VERY paranoid at this point. IT's not fuzzy/fungussy looking, but it's very light colored compared to the rest of their faces. I got them out immediately (about an hour to get all 3) and have them in QT.
Can someone tell me, is it normal? IT's triangular shaped and just lighter than their mouths. The biggest of the three shows the most. They're all 3 the exact same shape and color though.
