And that kind of resources can already be found online sadly for the untrained, inexperienced owners this can be misread and lead them to conclude to the worst.
Over the years I have seen people panicking because their animal had a reddish belly, and because they read somewhere that reddish belly could be scale rot they were already imagining the worse.
There are list of diseases out there (not very hard to find), but those are still not a substitute for a vet visit and a list of treatment as suggested is definitely not something that should be done for serious illnesses such as RI and/or others.
I understand giving advice for minor injuries (then again I would seriously question the person level of experience first) however recommending treatment for RI or mouth rot needs to be left to vets.
