Alright so I got this sailfin tang Nov 24. Since having him he’s been in Copper Power and on the 4th I added General Cure because I believed another fish in QT with him had flukes. The last week he’s been very pale and appetite hasn’t been very good. He’s still ate some frozen but won’t touch the nori anymore. Last night I decided to transfer them to a new QT tank with no meds. I did a 30 min H2o2 bath before putting them in the new tank last night. After the bath there was a little white round mark on his cheek. This morning it’s no longer there. He accepted frozen this morning but still no nori. Today he’s been flashing and doing some weird stuff. Since he wouldn’t take nori I tried formula 2 green flakes and he ate that but one time he had the flake just hanging out of his mouth and wasn’t eating it. Almost like his mouth couldn’t close it was very strange. He’s also done some random spasm type behavior today. I am going on vacation tomorrow and would like to dose something today if needed. I was thinking something bacterial but when the spot disappeared I thought it was like how us humans get skin bloching from peroxide. His tailfin at the tip looks a little discolored and frayed . He’s got some HLLE but I think that’s normal for being in copper for 2 weeks. One other thing the frozen he’s been eating the last 3 days has been binded with General Cure per humblefishs recipe for internal parasites. I did that because the other fish in QT who died wasn’t eating and thought maybe there were internal parasites that General Cure didn’t get so I used focus and binded it. The Sailfin has ate it the last few days.
