I would treat for two full weeks using epsom salts (100% pure magnesium sulfate with no additives - 1 tsp per gallon predissolved and added slowly over an hour) and kanaplex or if you can't find it furan 2.

Problem is the condition has already been partially treated with so many different medications.. hopefully you have not bread some resistance.

I would try to keep the nitrates under 20. I would increase your water changes to achieve this and make sure you are using a siphon as well.

Thanks everybody I'll give the kanaplex and epsom salts a try.

Just want to add something. While you treating you can make at least 50% daily water changes. Usually it better to do 100%water changes, but since your tank is big do as much as you can ,and just redose required dose of the salt and meds each time you do water changes. .Also wash and dry out the siphon or anything else that you will contact with sick fish and reuse.
Also for the future you still need to do more water changes for your tank(50% minimum)And you need to rinse the filter in the tank water WITH a water change, clean the walls, siphon weekly...

Well right now the two sick fish are in my hospital tank. It's only 5 gallons, so I do 100% water changes after each course of treatment. And I do clean out my siphon, since I use it to clean all 3 of my tanks. When I do vacuum the gravel in the big tank, I just have to be careful because the bettas will try to swim up the siphon They're trying to catch the tiny snails that live on my driftwood lol. But I'll up the water changes to get my nitrates down. Thanks again for all the help
