Joe,
The P.ocellatus has been with me for a little over 4 years. I got mine pretty early, before pictures or descriptions were published in aquarium literature.
The guy is timid, but extremely hardy. It once jumped onto hardwood floor and flopped around for (I would guess) 2-3 minutes. I investigated the "splat splat" noise, found him on the floor, threw him back in the tank, and he was out and about the very next day. Cool fish.
Wish my ex-Cirrhibrus sp. (C.rhomboidalis in particular) was that resiliant.
