老虎斑 has a firmer texture but very tasty. This one is pale yellow and is wild. Be aware of those darker in colour. Those are farm-raised and the flesh is much tougher. They should cost less too.
老虎斑 resembles the Camouflage Grouper 杉斑. But take note of the small spots covering the eyes. 杉斑 does not have them.
