Old Black Percula not swimming as much these days

[Jyetman]

My black Percula is now 8 years old his age I suspect 9 or 10 years. He seems to be taking his time swimming normally. When lights turn on "8 AM" hes in the back behind the live rock stationary swimming slowly. This continues until late afternoon when he comes out eats and acts perfectly normal. Hes been doing this for awhile now the late swimming. It has slowly gone further into the afternoon past 1 PM why is this?

So I just fed some food and hes out eating all seems normal?

My ocellaris hover a lot in one spot, usually where they are being hosted. Might be totally normal. How's the breathing look?

10 years is not that old for a clown really age wise, I know they can live well over 30 years.
Most just don't swim much, they have more of a nesting type pattern, keep to one place, usually a host of some kind
