Dottyback Aggression

[Cole_Voeller]

Hello all!
So a while back I got one of my dream fish, a super young springeri dottyback. Super cute dude, aquacultured, love him. I quarantined him with a Flametail blenny, and introduced the two together into their tank. A couple of times the flametail has chased the dottyback off, but other than that they have always been friendly. I got the dottyback young and aquacultured in hopes he would be more friendly. Today I introduced a diamond goby, and the dottyback immediately began trying to kill it. The diamond goby is probably at least 6 times as large as the dottyback, so the fact that the dottyback is going for it is incredible to me. I caught the dottyback (luckily it wasn’t too hard, he likes me), and put him in a breeder box to let the diamond gobys fins heal and to get himself established. Will leaving the dottyback in the box for a few weeks be enough to calm him down? Anything else I can try? Moving rockwork? Or could I put his breeder box into a different tank for the time being? The dottyback is a fish I’ve wanted for a long time, but I would hate for in a tank to only have a single blenny who mainly sits in his seashell, and one dottyback.
Thank you!
The problem child is livid about being in the timeout box

Dottybacks are know to be very aggressive. Maybe a "time out" in the breeder will help, but I can't say for certain.

I will say that my dotty back tolerated my clowns that were in the tank before him. . . but tried to murder anything that came after.

Yeah, I originally planned to get all the other fish I wanted, and then order the dottyback last, since I’ve never seen a store carry one. However a friend at my LFS knew how much I loved them, and called me saying he got one in stock, so it was in my car within 20 minutes haha. But your experience is why I’m thinking that I could possibly have some luck by sticking his breeder box into a different tank.
