So i took my jawfish out of my reef tank where he has been for 2 years at 78 degrees because he stopped eating, breathing heavily, his color isn't normal and he wasn't acting like his playful self. Put him in QT and gradually lowered the temperature to 70 degrees (was advised on R2R they like colder temps) and started treating him with Fritz Maracyn Oxy for fungal, fin rot and labor breathing. After 2 days of treatment he may be getting a little better. He'll kinda just float around in the water flow from the air stone then he'll wake up and swim for a minute. But still looks bad, breathing heavily and not eating (day 5). Any advice or if im treating him with the right medication?.
