Fish Fanatic
I get that, i was just pointing out that the filter media and hide have helped midagate the problem of the new tank, so basically its not entirely new bacterial wise
I have kept betta fish for several years now and I have lots of tanks, If that was my fish I would put him in a a quarantine tank, if the tank is cycled, great, if not I add something called Tetra Safe Start which adds the good bacteria. I always do daily 20% water changes in quarantine tanks to remove some of the bad bacteria causing the fin rot. I would also do daily salt baths with API Aquarium Salt.
And about your newly setup quarantine tank, I would get some sachem prime as that will detoxify ammonia and nitrites. Also try adding some Indian almond leaves as the tannins released are good for Betta.
If any other forum users wants to add to my advice please feel free.
