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
