I have a hippo tang in my QT and he is showing signs of ich. I have started cupramine dosing. Yesterday I got up to 0.5ppm and today 1.0ppm. He ate a pellet yesterday, but isn't eating today. He is pretty covered. My plan was to get up to 2ppm and maintain for 14 days. My concern is eating. I have nori in tank and tried mysis and pellets. Should I do a FW dip for relief? I did a 2hr ParaGuard dip before going into QT. He looked and acted perfectly fine during dip. Any suggestions and guidance is appreciated!
