Is my clownfish depressed?

I was considering the temperament of the Sunrise Dottyback, not the tank size. The Cherub angel was recommended for 30 gallons, but I'm okay with that. I need a semi-aggressive fish that can hold its own against Nemo, he's quite the bossy clownfish and I don't want him bullying the new addition.

I think getting a fish that's similar in size and temperament to the Cherub angel would be a good idea, rather than trying to find an exact match.
