The parasite embeds itself into the host's skin to feed on its tissue and blood. This causes the epidermal cells to proliferate and form pinhead-sized white spots that appear on the fins and body. It is usually introduced into the pond or aquarium on infected fish or contaminated equipment.
Damaged sweat and sebaceous glands, hair follicles, muscle cells, and nerves are seldom repaired. They are usually replaced by the fibrous tissue. The result is the formation of an inflexible, fibrous scar tissue. Human skin cells are capable of repairing UV-induced DNA damages by the process of nucleotide excision repair. [2]

[citation needed] The headgrowth is described as a "wen" by Chinese aquarists. [citation needed] The oranda is a metallic or matte scaled goldfish that is similar in appearance to the veiltail. It has a large ...
In the marine ecosystem, organochlorine contaminants like pesticides, herbicides (DDT), and chlordan are accumulating within fish tissue and disrupting their endocrine system. [32] High frequencies of infertility and high levels of organochlorines have been found in bonnethead sharks along the Gulf Coast of Florida.
