What common feeding practice for Humphead Wrasse was banned in regions like the Red Sea and Australia due to health concerns?
Answer
Feeding them hard-boiled eggs to attract them
A historical practice observed among divers involved attempting to lure or attract Humphead Wrasses by offering them hard-boiled eggs. However, this practice was subsequently banned in several key areas, including parts of the Red Sea and Australia. The reason for the prohibition stems from postmortem examinations conducted on the fish. These autopsies revealed evidence of elevated cholesterol levels, strongly indicating that the high-fat content of the eggs was detrimental to the long-term health of the wrasses.
