I ordered a Melenarus wrasse from Diver's Den a week ago as well as a goby. The goby died in under 48 hours. It started breathing rapidly then less than 2 hours later, began to spasm uncontrollably and die. Two days later, I noticed that the wrasse had some white dots on his pectoral fin, and also a small white powdery patch on his side. He also started having some kind of spasms every time I stressed him by putting my arm into the QT. I made sure he ate well, then dosed my QT with approximately 2.5 ppm Copper Power. 48 hours later, the spots have cleared up and he is having less spasms. However, they are still occurring less frequently. He is still eating very well. I read that flukes can cause spasms, but he is eating well, and I heard that dosing Prazi Pro in addition to copper power can deplete oxygen in the system. I thought of trying a quick freshwater dip to see it he has any flukes. Does anyone have anymore advice?
