So I've had my PBT for about 1.5 months now with no signs of any sickness. Healthy, eating well, with nori and frozen foods. This afternoon, I noticed the dreaded white spots on his body and fins. I added a wrasse about a week and a half ago that got stressed from the fish in the display and jumped into the overflow down into my refugium area of my sump. The wrasses has been in my sump for a few days now and I'm thinking he is the one that introduced the parasite into my tank.. I've since removed the wrasse and he is now in my 10 gallon quarantine tank. My questions is should I wait and see if the PBT gets better on his own? Or should I remove him now and treat in the quarantine with Quick Cure (Malachite Green). I've only had experience treating freshwater fish with Malachite, so any other suggestions on how to deal with this are appreciated. Thanks!!
