Hey guys. Yesterday while I was moving my foxface from my 60 gallon tank to my 210 gallon tank, it hit its head really hard on the glass of the tank around 3 times before I was able to catch it. Right after it got into the tank, I noticed that it was swimming weirdly and was staying in the same spot for the most part, I didn’t think much of it as it was probably pretty stressed from the move. Around a hour later, it was lying on its side on the bottom of the tank, breathing heavily. After seeing this, I placed it in a large isolation box and had to go to bed as it was super late. This morning, I saw it trying to swim around (still swimming weirdly) but was still lying on the bottom of the box for the most part but it was definitely doing better than last night. So my question is what should I do now? Should I let him back into the tank or should I keep him in the box? And does anyone have any idea what type of injury this could be?

I've had to put down my fair share of fish and it sucks
