Question Large white patch on my Betta! Help!

My blue betta has a white patch on his body at the base of his dorsal fin. It started out weeks ago the size of a pin-head and is now nearly the size of my pinky nail. I have done courses of Fungus Eliminator, Tetracycline, Ampicillin, and Triple sulfa. NOT at the same time , but consecutively as each course didn't work. I do regular water changes and use StressCoat and aquarium salt in his water. Patch just keeps getting bigger. He is eating and acting normal. Anyone know what it is and/or what I need to be doing? I have another betta I got at the same time (18 months ago) and his environment is identical to my sick betta, but he is fine. HELP!

Welcome to TFK, Kjt!

Could you please answer this diagnostics form? Also, I'd like to recommend that you post in detail how you did your treatment course on each med. Constant switching of meds is extremely dangerous. I wonder how long you allowed the treatment course per med. There is a potential risk that you may inadvertently create strains of bacteria that become resistant to antibiotics.
1. What is the size of your tank?

2. What are your water parameters? State the brand of test kit used.

3. Is your aquarium set up freshwater or brackish water?

4. How long the aquarium has been set up?

5. What fish do you have? How many are in your tank? How big are they? How long have you had them?

6. Were the fish placed under quarantine period (minus the first batch from the point wherein the tank is ready to accommodate the inhabitants)?

7. What temperature is the tank water currently?

8. Are there live plants in the aquarium?

9. What filter are you using? State brand, maintenance routine and power capacity.

10. Any other equipment used (aside from heater and filter which are two very important components of the tank)?

11. Does your aquarium receive natural sunlight at any given part of the day? What is your lighting schedule (assuming you do not rely on sunlight for our viewing pleasure)?

12. When did you perform your last water change and how much water was changed? How often do you change your water? Do you vacuum the substrate?

13. What foods do you provide your fish? What is the feeding schedule?

14. What unusual signs have you observed in your fish?

15. Have you treated your fish ahead of diagnosis? If so, what treatments did you use? State your reasons for planning ahead of proper diagnosis.
Furthermore, I would suggest that you stop adding any more salt in both tanks you have. There is nothing much it can do to help your fish and will not be any more useful other than as a corrective treatment process against some issues such as ich, flukes and costia.

Please include photos as well of the affected areas. Photos will help us pin down the exact issue aside from additional details.
