I was told that these spots a.k.a cotton mouth is a strain of Columnaris which is
a serious bacterial infection.
Do you have any suggestions on how to treat this successfully? I have read too many different things. Currently using Minocycline.Yes it is. And later scientific studies suggest it is a water column borne opportunistic pathogen. After the treatment you may want to look into doing more water changes and perhaps evaluate the day to day habits, fish feeding, fish diet, filters, fish density, CO2 levels, etc...It is hard to tell what triggered it.
If you've caught it early, the chances are you've halted it with the antibiotics, providing you got the right ones. I dealt with it once and it never returned.

Can I use these in a planted tank with inverts?
