At first royal grammas will hide a lot so it’s normal if it doesn’t come out a lot. As far as the fins it looks like fin rot but I haven’t dealt with that issue in ages and when I did notice it on my fish it was to late as it died the next day. I’d say just feed it good 2 times a day with mysis.
It's also possible the clowns are picking on him. Clowns are known for attacking as a fish is swimming away, so it may be possible they are nipping his fins as he swims away if they are defending their area or nem. You might try treating him for fin rot just in case but also be aware of the possibility of the former.
