My Yellow Tang that I've had for almost two years just started going crazy when I came home from work today. He is usually very peaceful and normal. Today he is being very aggressive, swimming sideways and sometimes upside down and generally going nuts. I checked water and everything seems alright, the rest of my fish are being completely normal. I haven't made any changes to the tank in almost two months. When he slows down his body looks fine, no noticeable parasites or injuries. Has anyone seen this before? Any ideas?
