Fins look a bit tattered. Maybe just the photo? Any aggression in the tank. Other tangs? Did your electricity go off during the night? Could someone have sprayed aerosol cleaning or air freshener near or in the tank? Could you give us a full shot of your tank? Thx.

Fish have all been together for at least 3 years . No power outages that I’m aware of plus system is ran off two backup battery power supplies

only thing I did notice last week was tds for Rosie water was at 19 and I ordered new filters but I wouldn’t think that would cause him to die that fast

even when i filter out water through my RODI unit i still run alittle bit of doctor tims in the water just in case something made it through as a failsafe.
