Howdy jwwoodjr, I'll take a stab at this, and say that looks like a flexibacter columnaris symptom. I have not had to treat for this, but I do know that it is a gram-negative bacteria. So water changes for sure. And an anti-biotic may save your oto. I am sure that others here with more experience will be able to provide more info. Good luck and welcome to TPT.
