Diamond Goby kicked the bucket need advice (dead fish photos)

So I’m aware this guy is done for. Of course he is the first fish to crash in a long time. I hadn’t seen him in months, but in the last week or so he reappeared. Last night I noticed he was swimming to the top and then dive bombing falling on his head. Today I found him on his back, when I went to net him, he’d upright momentarily but then fall to his back once more. The reason I’m concerned is my Biota Hawaiian Tang…. Arrives tomorrow. Water parameters are fine, several other fish are doing just fine. Anyone spot anything?

Tank launched in January, he probably got In around March. Yes to pods, I feed a mix of nori, frozen mysis, nori, and flake. I do suspect that I have leftover Dino or diatom? You can see it on back glass in attached pic, wondering if he would be poisoned from that if he’s sifting it on sand? I will add that I have a fairly deep sand bed, that because of the way I built in my tank I never vacuum. Thanks for being willing to assist!

could be just one of the ones that could not be helped, you stated you have others and they are fine.
