Can I put a Royal Dottyback in my 29 gal?

I have a 29 gallon SW setup with just a few pieces of live rock--I might add more down the line.
The tank's inhabitants are: Spotted hawkfish, tomato clown, and a yellow-tailed blue damsel.
I also have a small horseshoe crab who doesn't come out very often. He was a bad choice for my tank but don't rebuke me because it's too late now!
But would a pseudochromis work with these fish? I don't know much about them.

Honestly, prob not a chance in you know what. Thats ALOT of aggressive fish for a 29g. The YTD and maroon would prob kill it ASAP, if not they'd just pick each other apart.

I'd def be adding more rock to the tank so your fish have their own territories.

Haha, okay! The fish have been getting along just fine, but I will look into getting them more live rock.
