HELP chevron tang not eating

[Jayp5117]

So to start my chevron tang stopped eating as of yesterday. He has been in he tank for 3 months or maybe a little more now. He has always been a pig and loves his algea. But for some reason he just quit eating and is acting a little odd. I had a watchman goby go crazy the other day spinning around and going crazy until he died. All my other fish look fine and the chevron does as well. Parameters are 1.025, 78°, and all other levels are at zero. No idea what could be causing this

Wow! Sounds like "whirling disease" that you see in freshwater fish like trout and some others. It's a brain parasite from what I've read/remember. Not good.

check for any stray current

I would be willing to wager flukes and/or internal parasites. A freshwater dip can tell you if there are flukes.

Update: I did a good water change and tested parameters again but still would not eat. Tonight I was going to set up my hospital tank and figured I'd try to feed one more time and before I put the food in the tank he was at the top waiting for it. So thankfully whatever ticked him off he is over and eating like crazy again thanks everyone.
