Betta suffering?

[paula1010]

5 gallon tank
1 betta and 1 catfish(there used to be 2 but one died 2 days ago)
water parameters are on range (API master kit)
water temperature is 72-74
The betta first showed signs a few weeks after we bought him and the catfish (new tank). The betta started with a white saddle patch that grew larger over time. I treated the tank with Maracyn, which did nothing, I've done many water partial water changes.
I am currently treating the tank with salt, Furan2 and Kanamycin (3rd day today)
Baths twice a day with salt and MB, when I first started the baths about 2 weeks ago my betta felt much better but now he is in one spot, sort of floating, a little bit to the side and not eating.
It breaks my heart to think he is pain, I don't know if I should try different medication or if he should be euthanized.
Can someone please help?

Sorry for your Bettas sickness.

I think you are following a good course of action.

I would include the Furan2 and Kanamycin in the baths as well, at even double the normal "in-tank" dose.

Make sure his tank water is 75F or even a little lower, but not higher.

Increase salt in the tank water to 1 to 2 teaspoons per gallon.

Make sure the tank is also mineralized starting with a GH of 150+.
Products such as SeaChem Replenish can help, but the most simple is a Wonder Shell at 1/4 to 1/2 does for a Betta
