Aquarium caretakers are responsible for maintaining the health and cleanliness of aquatic environments, such as fish tanks and marine exhibits. Their duties include monitoring water quality, feeding the inhabitants, and cleaning the tanks to ensure a safe habitat for fish, coral, and other aquatic life. In addition to daily maintenance, aquarium caretakers also observe the behavior and health of the animals. They may assist in the breeding of certain species and educate the public about marine ecosystems. Their work is essential for the well-being of the aquatic creatures and the overall success of the aquarium.
