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.

“The middle years of parenthood are characterized by ambiguity. Our kids are no longer helpless, but neither are they independent. We are still active parents but we have more time now to concentrate on our personal needs. Our children’s world has expanded. It is not enclosed within a kind of magic dotted line drawn by us. Although we are still the most important adults in their lives, we are no longer the only significant adults.”
—Ruth Davidson Bell. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
“The new concept of the child as equal and the new integration of children into adult life has helped bring about a gradual but certain erosion of these boundaries that once separated the world of children from the word of adults, boundaries that allowed adults to treat children differently than they treated other adults because they understood that children are different.”
—Marie Winn (20th century)
