Hi, I bought a guys full system. I had issues with what I thought was bad white spot. We pulled this fish out of a 3500l system and performed a fresh water dip and found this weird parasite on it. Fish is fine in quarantine and eating. The problem is the fish I bought went into a couple of different systems and we need to treat but don’t know what this parasite is. The fish were quarantined in low salinity and cupramine and the fish looked in perfect health eating like machines before they were put into other systems but one rookie mistake on not FW dipping has put all the other fish in the systems at risk.
