Funny thing though. I'm on day two of NGP in my QT for some mouth problems on a butterflyfish, and a carpenter's wrasse in the same QT is very unhappy. It could be a coincidence, but he had been fine for the prior week. I know wrasses can react badly to some meds, but anyone have this kind of adverse reaction to NGP from a wrasse? FWIW, the butterflyfish couldn't seem to care less (thought they do appear a bit loopy).
