Reddit mentions of Kanaplex, 5 g(0.18 oz)

Wow, he does look really rough. You could try Kanaplex or Maracyn?

You can get kanaplex or Furan-2 (nitrofurazone) on amazon via prime.

I am an advocate of Kanaplex because it saved my boy. Read up on it, see if this is right for you.

I think that Seachem Kanaplex would be more helpful for the fin rot. It cured my fish in two treatments. Hope this helps!

Seachem kanaplex

The photo clearly shows damaged gills and dormant behavior. Flukes infestation combined with ammonia typically leads to that. It appears as if a fungal infection is kicking in. (Flukes slowly kill and cause tons of fungal infections in the process)

OP, your best bet is going with Hikari's PraziPro or Seachem's Paraguard, stress coat, and serving soft fruits / vegetables to boost the immune system. Then dose Seachem's Kanaplex separately to deal with the fungus.

BTW, can you show off photos of the entire body for better judgement? If it's ICH, Hikari's Ich-X alone would beat the daylights out of the ICH and fungus at the same time.

But be careful, while it's highly effective, Ich-X contains some cancerous stuff to human health. I recommend to go with Seachem's Paraguard for ICH, but it will take longer. You can combine Paraguard with Kanaplex to deal with bacterial infection if that's the case, but make sure to pump oxygen in the take since meds reduce it.

I am new to this, but I asked the same question to my bestfriend which she’s obsessed with Bettas and she told me to buy Kanaplex it worked really well and it only took two or three weeks for him to recover. Again I am new to this and I don’t know a lot about Bettas but i’m slowly learning. Good Luck.
