Back in the mid to late 50's fish and wildlife (or some official branch along those lines) thought it would be a clever idea to introduce 10 or so species of fish to the Hawaiian Islands. Well, three have survived and two are pests. Our grouper is now found all over the reefs, quite thick in many places.
In theory they're good eatin', however they do carry ciguaterra toxin. Ciguaterra toxin isn't something you'd really want to deal with. It's sort of like lyme disease light, and apparently is occasionally mis-diagnosed as multiple sclerosis. Not something you want to deal with.
Argus groupers, what a pest...
