Pat, Randy at the Chemistry Forum suggested cleaning the qt tank that had been treated with copper with straight vinegar or a muriatic acid solution. He "thinks" this will clean it properly but suggested that the tank get tested with a snail or less desirable invert first for a couple of weeks.
Per advise of others, we will not be treating our qt with copper unless/until the fish shows signs of disease. It seems it would mess terribly with our biological filtration system. Right now the silly fish keeps laying over on it's side and playing dead. Seems this is normal wrasse behavior. In the mean time, I am having palpitations thinking we are in the process of loosing our second fish!! If this stupid thing lives, I might have to name him something really bad. Something this forum does not allow to be posted. Something that goes well with his legal name.
