I’ve had two good-sized yellow tangs that I picked up from a fellow reefer about 7 - 8 months ago. FYI, he had had multiple yellow tangs in his tank. These two tangs have been together for quite some time. Everything was copasetic up until about a week ago. All of a sudden they are facing off, with the larger one trying to tag the smaller one. What would cause this? Is this love? Nothing has changed in my tank for some time.
