How do you know if sea bass is over cooked?

Sea bass is overcooked if it becomes dry and flaky instead of moist and tender. The flesh should be opaque and easily flake with a fork, but if it appears tough or has a rubbery texture, it has likely been cooked too long. Additionally, the internal temperature should ideally reach around 130-135°F (54-57°C) for optimal doneness. If the fish is significantly above this range, it may be overcooked.
