Looking for input on Rollands Damsel or Clown options

[Quietman]

I have always planned for one or two more fish and originally was considering a clown goby, but the good folks on here have dissuaded me from a potential coral problem. Thanks!

I have a smaller tank (RSR170) mixed stony but LPS dominant. All my current fish are smaller and on the peaceful side of the behavioral spectrum, I'll list below.

Just worried about fish additions that could turn aggressive (so no conspecifics), and have heard the Rollands damsel is less aggressive than most. I also am considering a single (to prevent mating aggression) Ocellaris clown as they're the most peaceful, but worry it can still be a bit aggressive and potentially damage corals. Any other options that won't start a blood feud or excessively damage corals would be welcome suggestions.

I know there's always risks, just want feedback on experience to maximize my chances for success.

I’ve a trio of Rollands in my tank. They bicker amongst themselves but leave other fish alone. I have Talbots also and they’re even mellower. I do have a very large tank and a lot of different damsels to spread out any aggression.
