Hey fellas, I just got a Royal dottyback and I love it! I intend to buy another. But my question is, can two unpaired royal dottyback co-exist? I do not want to buy another and find out they will kill each other.
They will probably kill each other. Check out the Pocket Experts Guide MARINE FISHES page 120
"Inch for inch, one of the most aggressive dottybacks available"
"It is reported to maintain a territory of several square yards in the wild, so keeping more than one in anything but a very large home aquarium may be foolhardy."
