Wow! Irrespectively of species these are great trouts! I never landed coral trouts above 4-5 kg, so in comparison these are real monsters.
Just checked the IGFA records (via iPhone -> IGFA app).
IGFA records (all tackle):
Plectropomus laevis (coralgrouper, blacksaddled): 24.2 kg, 1997, Japan
Plectropomus oligacanthus (coralgrouper, highfin): 1.2 kg, 1994, PNG
Plectropomus leopardus (coralgrouper, leopard): 7.4 kg, 2002, Japan
