I have noticed that some of my fish have developed (cottonmouth) or (mouth Rot). It looks like white fuzzy mucous that builds up around the inside of their mouths, and I have noticed one of my Pumpkin-seeds actively spitting it out. I do frequent water changes and I have ample filtration so I am not sure how they got the mouth rot.
The cottonmouth comes and goes, one week a fish will be exhibiting symptoms, and the next week it will be completely gone.
One possible cause is from their diet. I feed them a mix of flatheads, danios, guppies, mealworms, waxworms, and night crawlers on a daily basis. Some of he guppies have looked like they were in poor shape, and I haven't quarantined any of my feeders because my LFS claims that they do that for me.
How do I go about treating this issue? Can I treat it in my tank? I have a heavily planted tank with fixed structure, so removing the fish to transport them to a quarantine tank would be bordering on impossible.
I have attached some photos below but it is really hard to see in the pictures. I also added a photo of my tank so that you get an Idea of why i will not be able to remove the fish, (they have tons of heavy rocks and driftwood to hide under) and I do not want to take apart my arrangement.
