I have a tang who is a straight butthole. I tried putting a new foxface of simular size in the aquarium and randomly he will attack him. Other times he seems fine. My Fox is always on edge in that tank so i put the fox in my QT tank for now. Am i able to rearrange my rock work or remove the tang and put him in time out for a few days and reintroduce him? Or am I looking at setting up another tank?
