aquarist

An aquarist is a person who manages aquariums, either professionally or as a hobby. They typically care for aquatic animals, including fish and marine invertebrates. Some may care for aquatic mammals. Aquarists often work at public aquariums. They may also work at nature reserves, zoos, and amusement parks. Some aquarists conduct field research outdoors. In business, aquarists may work at pet stores, as commercial fish breeders, or as manufacturers. Some aquarists are hobbyists, also known as "home aquarists," who may vary in skills and experience.
