Disease/parasite that only goes after scorpionfish?

[2026_1]

Hi everyone, the past month or so I have been trying to fight this disease or whatever it is in my tank, so far it has killed my fu manchu lionfish and yellow spotted scorpionfish and has infected my dwarf fuzzy lion on and off for the past month. The symptoms are just cloudy eyes and breathing heavily. I have clownfish, a hawkfish, and a wrasse in the same tank and they have shown no symptoms at all which i find to be strange. I have tried kanaplex, ruby reef rally, and prazipro and none have shown any difference on the fish. My fuzzy lionfish looked fine for a little while but shes now back with the cloudy eyes and heavy breathing. Does anyone have any leads or suggestions for what this might be or how to deal with it?

There isn’t a specific disease that only infects scorpionfish - but flukes can be more specific in their hosts than protozoan diseases are.

Can you post a video of the fuzzy under white lights?
Is it still eating?
