At the moment I am going through the soul destroying process of removing dead fish from my aquarium because of whitespot. I dont have a hospital tank. I have been treating them with exodin. My water quality is just about ok ....just live rock and a powerhead keeping it going. My question is.... If i lose my fish will invertebrates and crustations become host to the parasite. My intension was if i lose fish just let it be for a few weeks then restock.
