I was gone for four days, noticed this on the top near the now lost dorsal fin of one cory (10 in medium-density planted tank, 6 otos, several cherry shrimp, nerites). Started water changes but I don't know what it is so I don't know what to medicate. Everyone is acting normal & eating. No flashing that I have noticed.
Thanks!
