I just got a powder blue tang on Saturday. He is already picking away at the nori and some flakes. I know they are huge ich magnets so I've been watching him very carefully. I don't see any spots on him but he is flashing against things. I know it can be in the gills where you can't see it, but I'm wondering if this is ich or flukes? Which should I treat for? You can't do prazi and cupramine at the same time.
