Sad news the PBT died last night. Not sure of cause. After everything I was hoping he'd pull through, but he never really seemed right after the CPR. Wonder if there was extensive damage to the gill tissue as I had to keep full air with a bubble stone, power head pointed to the surface, and had the temp dropped to 74. The smallest exertions had him breathing hard. He also seemed to have issues with swimming into walls and keeping himself off the bottom. Fish just never seemed right after the initial infestation with parasite, my guess is tangs are more sensitive and suffer more complications from heavy infection or at least my 2 tangs did and they were some of the last to get into treatment.
On a better note everyone is eating and doing well in the 40b and no one is in active treatment for disease
