I bought a Royal Dottyback in Jan. 2014, went fish shopping with the wife and she fell in love with it. Even though a little voice in the back of my head was saying "Don't do it, there is something about dottybacks you've forgotten!" I bought it anyways. Got home, looked it up and went "****!" LOL. QT'ed it with the black clownfish bought the same day for 30 days then put it in the display tank which only had a PJ cardinalfish and yellow tang. Right off the bat it went after the PJ who I had had for almost 10 years, I wasn't happy. Kept an eye on it, would tear up a fin, then leave the fish alone, then tear up another fin, seemingly as soon as the first fin healed. Was at the point of removing the dottyback, about 3 months later, and noticed it seemed to be leaving the PJ alone. After about 3 months, it would only bug the PJ once in awhile, you'd see a tore-up anal fin, it would heal. Month or so later maybe a rip in the dorsal fin, then it would heal. Stopped bothering the PJ about 6 months after it hit the DT, would swim at it at feeding time but the PJ is smart, just yields a few inches, dottyback backs off, PJ moves back where it was. PJ used to sleep somewhere in the rocks, started sleeping off to the side along the back. Recently added a lawnmower blenny, was afraid the dottyback would give it grief, but its actually a little leary of it, the blenny has never gone after the dottyback, but if it happens to dive into the live rock and goes by the dottyback fast it flinches. So long story short, it settled in pretty well, never bothered the clown or the tang, never bothered Coral banded shrimp I have and other than bugging the PJ for about 6 months (and never bad, if it had gotten bad I would have removed the dottyback) its been a pretty neat fish, both looks and personality-wise. Oh yeah, and after giving the wife gthe rief for making me buy a fish without researching it, I hear "See, I told you it would be OK" every once in awhile when she is watching the tank.
