Borbonius Anthias help

[losthere]

I have a borbonius anthias that I believe has some sort of bacterial infection. At first it was a small spot where there were some scales that were raised. At first I was thinking flukes, but yesterday the spot turned to an open wound. I was wondering if my diagnosis of bacterial infection is correct. And also what would the most effective treatment methods. I was thinking of doing some medicated baths as this seems a little less evasive and don't have to medicate the whole HT and keep it a little more stable, but don't know if that would be effective enough. Any help will be greatly appreciated.

If he's already in QT and it looks like it's getting worse, I would treat the entire tank with antibiotics. Furan-2 would probably get the job done (if this is, in fact, a bacterial infection). A pic might help confirm your diagnosis.

Will try to get pic.
I am a little reluctant to treat the entire tank, and kill off all the good bacteria and cause the tank to re-cycle and possibly killing the fish that way. I haven't had good luck with that. Anybody have a method for that process that might help me?
I have seen youtube videos of people treating their koi with iodine and a wound sealer. Would this method work?
How about if done in conjunction with baths of furan or methylene blue?

Without performing a skin scrape, culture or gram stain its impossible to diagnose what your fish is suffering from. Best guess without seeing any conclusive evidence would be a uronema or bacterial infection. The former is incredibly difficult to treat once established in a wound. Do you know the water parameters?

I presume you do not have access to a microscope or gram stain equipment. Based on this your best course of action would be to treat the entire QT system with a strong gram negative and positive antibiotic. Additionally I would assume the wound is infected with uronema which will require a strong anti protozoa medication such as metronidzaole. Concurrent treatment at maximum dosage for 10-14 days. Be sure to closely monitor the water parameters and perform water changes as necessary.

What gram negative and positive antibiotics do you recommend?
