Head and lateral line erosion, also known as HLLE, hole-in-the-head disease, or HITH, is a fish disease that affects both freshwater and marine fish in captivity. Sometimes marine head and lateral line erosion or MHLLE is used to refer to the marine version, though the causes and treatments for each are similar. Among freshwater fish, it affects cichlids and angelfish, with Oscars developing the disease more frequently than other related fish. Angelfish, tangs, and groupers, and to a lesser degree lionfish, damselfish, and clownfish are susceptible in marine aquaria.

He had already guessed very accurately at our ages, and said that he was forty-eight.”
—Henry David Thoreau (1817–1862)

For us, the answer will be clear, established and for all practical purposes indisputable: The purpose of life is to produce and consume automobiles.”
—Jane Jacobs (b. 1916)
