Hey gang! Weird issue I have encountered the past few days...
My tang (Ctenochaetus flavicauda) has been in my tank for close to 2 months now with minimal aggression. The only other broad bodied fish in the tank is a yellow blotch rabbitfish and he is not aggressive at all towards him. In the past week, however, he has began bullying my male Lineatus Wrasse and my Watchman Goby to the point I don't see the goby much and the wrasse is hiding at the top corner near the overflow box.
I feed 5 or 6 times a day and they get a full sheet of nori every other day, so I don't think it's a feeding issue. What would cause a tang to suddenly change behavior like this and go after fish that clearly aren't direct competitors? I would have expected aggression towards the rabbit, if anything...
Anyone else had a similar experience?
