Some decent info, but lots of falsities. Firstly, columnaris is not a fungal infection - it is bacterial. And can be very dangerous. As for bloating, if it’s a mild case where a fish is not displaying dropsy, Epsom salt seems extreme. There are much better alternatives for a simple case of bloat.
Treating Betta Diseases
Guide to curing bettas with diseases
Nice info, but some parts are mistaken; like "dropsy is a fatal disease". Dropsy is not a disease, dropsy is a symptom caused by many things and is usually not curable for it means kidney failure most of the time. Overall this is a good article for beginners that are getting into the hobby. Good job.
Overall, again a good basic explanation of various betta diseases. However, their are some minor problems. Firstly, popeye isn't a disease but actually a secondary infection similar to dropsy. I would of also of like to here what each of these infections are. A disease name and then matched to a bottel isn't understanding what your fighting or what the fish is going through. For example, mentioning that columnaris is a gram negative infection. this is going to help people know what their looking for instead of just a bottel with a disease name on it. I also wrote a response about salt usage in your other article. To some it up, 50 years ago, salt was the only thing to treat fish with. Now, we know that salt is a myth and rather harmful to your fish and especially too bettas even though many people still use it.
