I would like to say that I don't think this fish will make it. I've never had a more odd experience with a fish before in my life. I took him out of my main take and placed him into the quarantine. The fish got very very stressed out and darted all over the place. Eventually he started laying on his back. After a while I figured he was dead. I went to scoop him up, and he darted again. I figured he was either basically dead or under extreme anxiety. I didn't have much faith in him living and I didn't want the parasite to infect my QT tank. After about 2-3 more hours, I saw him lying on his back, basically dead. I went to scoop him up, this time I perfectly scooped him without issue. He didn't dart or anything. I figured it was time to dispose of him, but I put him in a bucket filled with water from the main tank. I figured maybe, the QT tank parameters were too different.
The next day I wake up and I still see him lying down, same spot, looked dead. I looked at the bucket, tapped it to see if there was any reaction, and there was nothing. I figured at this point, he was definitely dead. I was kind of sad, but kind of relieved. Fish are very stressful to deal with. I was planning on disposing of it all day today, but ran out of time. At 1AM, to my absolute surprise, I see him swimming again. This time he looks perfectly normal. Swimming much more than yesterday. I'm beyond confused. I hope he'll live, but I just feel completely weird about the entire situation. The emotional roller coaster i've gone through is drastic. I regret not buying a pair, maybe that would've made him more comfortable.
This is definitely the strangest experience I've ever had. I'm really not sure where to continue. I am considering returning him to the main tank. I'll risk infecting the rest of my fish, but they seem to be doing fine with high temperatures.
I feel like with all the changes it's unlikely he'll survive. But as I say this he is swimming normally. very weird.
