Call me crazy...but that looks like a small Jaguar Guapote (aka Rainbow Bass) from Central America (Costa Rica, Nicaragua...)

. They can get to be a few pounds. In the larger specimens, the spots will become smaller with respect to body size. The markings will also fade and in some cases, the roll of larger blotches on the lateral line becomes more like a solid line. Males will develop a hump on the head just like the peacock bass males. The Jaguar Guapote is a cichlid afterall just like the peacock.
Scientific name: Parachromis managuensis (according to FishBase)
I saw a fishing show on TV a couple of months back and the host said they fight pretty hard for their size. They love structures so you really have to crank them out before they can dive right back into the nasty stuff.
Totally cool!

And congrats on this fine catch without even stepping off Oahu to catch it! I would submit it to Hawaii Fishing News to see if you can get it on as a record catch. I don't think they have an entry of a Jaguar Guapote yet.
I guess I'll have to try harder next time to look for one of those. Anyone seen more of those around (when they might have been identified as a brown red devil?)
Here are a few pics of some Jaguar Guapote from South America. The large round blotches on the lateral line and the marking on the body tipped me off.
