Need help with infection!

[Calvin4924]

I have a very large aquarium that is separated by a sheet of acrylic with holes drilled in it. on one side is 2 juvenile Oscars and on the other is a parrot Cichlid/hybrid of some sort and a juvenile arowana (they have plenty of room and will be moved to a pond once big enough). My parrot Cichlid started developing small white jelly like bumps that developed into white stringy fungus like infection on scales and fins after losing a couple scales when he lived with the oscars. I first did a significant water change and added salt. within a day the infection was gone. but now has returned worse. I removed the carbon filters and started using P imafix fungal treatment. now on the 3rd day of treatment, one of the oscars has developed the same stuff on his head. shouldn't the treatment be making it go away? not spread to the other side of the tank to a fish thay had no contact with the first infected fish post infection? My poor parrot is being completely overwhelmed and now spends most of his time upside down trying to swim but is covered in whatever this is. please help it's spreading at an alarming pace. I included a pic of the Oscar. it's very blurry because he doesn't stop moving.

That may be a Bacterial outbreak so the Pimafix may not be affective. Tbh don't know what med you should be using so will let members chime in with their advice.

Just an update. Unfortunately my parrot died within hours of posting. I'm starting to believe that it is bacterial and not fungal due to the spreading between fish and the fin decay

Would start kanamycin and furan2. Keep the salt at 1 tsp per gallon. Would get water parameters and keep the the water super clean. Watch the other fish. Treat the entire tank.

Do daily water changes and make sure to use a dechlorinator.

Would treating with API Triple Sulfa be a good choice? it's an antibacterial that treats symptoms consistent with what the parrot died from.

If they share water they have contact. How big is "a very large tank"? How much filtration are you running? Is there filtration on both sides of the divide? What's the temp? Parameters?

If you are using salt, you need to be writing down what you are adding as you are doing water changes so you don't over do it and you maintain salinity. Meds shouldn't be advised until forum has a clear understanding of the environment the fish is in. These are important contributing factors that cant be ignored.

Triple sulfa can work but not as well if it’s late. Would suggest what I’ve mentioned as it’ll cover columnaris. As already mentioned have to keep pristine water (0ammonia, 0nitrite, and <40ppm of nitrate).

Generally Oscars can live in a wide range of tank sizes, conditions, etc.. they're super hardy so possibly may have gotten the infection from the parrot. At this point depending on what you have in your tank best solutions for treatment were already mentioned though just another idea to perhaps separate or isolate quarantine attempts. When something like that happens best is to run your tank back from scratch & contain each fish in their own quarantine space, each with a different solution (targeting same indications) then could share results towards preferred/best fix. Treating your main tank imo just causes lots more problems in the long run, stresses out other fish that haven't been infected, leaves trace, lots of reasons bro. GL+
