Help with Diamond Watchman Goby

[YoNight]

Looking for your opinion about my Goby. 4 days ago he/she stopped eating, stopped gobbling the sand, and has been breathing heavy and not moving around very much. I have had him for 1 year and tank is 4 or 5 years old at this point. He's been an absolute workhorse sifting the sand for the last year so its very out of character for him to just be sitting around breathing like this. Don't see any white spots on him.

Parameters:
Salinity 1.0255
Ammonia : 0
Mg: 1350
Ca: 430
Alk: 7.5
Phos: 0.2
Nitrate: 12
Temp: 79

Under white from yesterday


Under Blue from 2 days ago (but not looking too skinny at end of clip)


I did add a small clown 1 month ago. Currently everyone else is looking healthy and behaving normally. I don't think its O2 related as my skimmer makes a lot of microbubbles. LFS suggested he may have ran into the glass and bonked his head. But wondering what the experts here think and would recommend.

Fish looks quite a bit thin. In addition, I dont believe water is an issue but rather something it ingested (can be a bristleworm as example) or gill issue such as flukes. I suggest isolation using fresh tank water and addition of air stone and treating with PraziPro or even General cure as a method of prevention of gill issues if applicable

What are your thoughts on a fresh water dip at this point? I don't want to stress him out more than I have to if it it due to something he ingested. Feels impossible to know for sure. There are bristleworms in the tank/sand and under the rock where he resides at night.

While FW dip can offer relief if flukes, when a fish is breathing heavy, it can impose additional stress however with an airstone may be a safe application
