Could not catch Blue Hippo Tang who was the worst of them. Started lowering salinity in QT. everybody looking good. Finally caught Dory, did freshwater dip and put her in QT. 2 days later my flame wrasses and convict tang were dead. Rest of fish looking in distress. Dosed copper as last ditch effort. Had mixed results. All fish perked up some in 24 hours except for Dory. She was doing death dance so I pulled her and ended it quick for her. Within 24 hours no Ich noticeable anywhere and even Fairy Wrasse who was lying sideways at bottom of tank was swimming around and all eating voraciously!
Here's my question... How long do I dose the copper?
I still have a small gramma in MT which I thought was dying but now is spot free and eating great and not flashing. I can't catch this guy to save my life! I also have a diamond goby in the MT that I don't know what to do with. Do I put sand in a separate QT and move him. I know I need the MT empty for 6 weeks or so but man the water changes on the QT are getting annoying and my nitrates are still high.
Any advice for a moron who didn't Quarantine his new wrasses before putting them in to population?
Hopefully you brought salinity back up over a few days, that will stress fish and possibly kill them bringing it up too quickly. Do you have a refractometer to closely monitor the salinity as well as check the pH as you have to buffer it with hypo. Also, copper and hypo don't mix, hopefully the salinity is back to normal. Low salinity makes copper stronger.
As for the wrasse, put a plastic container with sand in QT, it can sleep in it and it is easily removed to clean or change out the sand.
Copper is kept at a certain level (need copper test kit) for 2-4 weeks. It depends on what you are using. Also, you can't use amquel or prime with copper, it can create a deadly level of copper.
