Key Facts & Information

Overview A summer day at the beach can be very relaxing. The sand is warm and the waves lap gently on the shore. But beneath the water's surface is a world that is teeming with rich plant and animal life. For many of us, it isn't possible to experience this world firsthand. But at a public aquarium, we can take a peek and examine close up the beautiful fish and coral. An aquarist cares for the animal and plant life that you see in those aquarium displays. Aquarists make sure that all of the animals and plants in their displays are well fed and free of disease.

Training, Other Qualifications

Nearly all aquarists need to be certified scuba divers before they can take their first aquarium-related position. Certification classes are available at many two- and four-year colleges, private fitness organizations, and diving companies. Candidates interested in becoming aquarists must first intern at an aquarium, zoo, or research lab.

The salary range is quite large depending on location and experience. Starting salaries can be as low as $18,000 to $22,000 but for more experienced people at top institutions the salary can rise to nearly $50,000.

Education and Training

The minimum degree required for an entry-level aquarist position is a bachelor's degree in marine biology or zoology.

Nature of the Work

Aquarists are just like zookeepers, except their charges live under water. Aquarists take care of fish and other aquatic creatures at large aquariums. They feed and monitor animals and maintain exhibits. Aquarists check the temperature and conditions of fish tanks. They look for any medical problems with the animals, such as injuries, sluggish swimming, and lack of interest in food. Aquarists also prepare food with vitamin supplements for all the fish under their care.

Aquarists' duties include cleaning tanks so that patrons can fully enjoy the creatures within. They take water samples and analyze them with pH strips and laboratory equipment to make sure that the water filtration and temperature systems are in working order. Clean water keeps fish healthy.

Many animals come directly from the wild. Aquarists collect creatures and plants from freshwater and seawater a few times each year. They must be prepared to travel internationally and have travel documents such as a passport. Scuba certification is also a must in order to collect interesting specimens.

Some aquarists train seals, dolphins, and other marine animals to perform tricks and interact with humans. They are responsible for keeping their animals mentally engaged and do so by creating stimulating environments. Training can make caring for the animals easier.

Work Environment

Aquarists work in a variety of industries, including public aquariums and zoos, education centers with aquariums, marine research labs, state and federal agencies for natural resources, theme parks, and pet and aquarium stores. Aquarists have variable work schedules and often must be willing to work on weekends and holidays.

Some positions require travel to local and international sites for specimen collection.
