AQUARIST CAREER GUIDE

An Aquarist is a professional responsible for the daily care, health monitoring, and husbandry of fish, invertebrates, amphibians, and reptiles within a public aquarium or zoological institution. In a given week, an Aquarist prepares species-specific diets and performs SCUBA dives to clean exhibit interiors and deliver target feedings. This role collaborates closely with veterinary staff and curatorial supervisors to manage disease treatment plans, specimen transport logistics, and compliance with AZA accreditation standards. Based on Lamwork's research across Aquarist job data, water quality management and life support system maintenance are among the most consistently required competencies across open positions nationwide.

Prepare species-specific diets and feeding schedules to maintain assigned specimens at healthy body condition.

Monitor assigned collections daily for behavioral and physical signs of disease, reporting abnormalities to veterinary and curatorial staff.

Maintain closed life support systems including mechanical filtration, UV sterilization units, and water chemistry equipment to meet species requirements.

Conduct water quality testing on a rotational basis, adjusting chemical parameters to keep all systems within established safety thresholds.

Support exhibit design, system fabrication, and interior cleaning through routine SCUBA dives and hands-on maintenance work.

Lamwork's review of Aquarist postings shows that life support system competency and hands-on animal care experience are the two skills that most reliably separate qualified candidates from the broader applicant pool.

• Hard Skills: Water Quality Testing And Chemistry Management, Life Support System Operation And Maintenance, Disease Identification And Quarantine Protocols, SCUBA Diving For Exhibit Maintenance, Husbandry Record-Keeping And Database Entry.
• Soft Skills: Observation, Attention to Detail, Communication, Problem-Solving, Teamwork.

Typical Career Progression for an Aquarist:

• Junior Aquarist
• Aquarist
• Senior Aquarist
• Aquarium Curator

Most professionals reach the Senior Aquarist level within five to eight years of consistent hands-on experience in a public aquarium or zoological setting. Advancement is driven by demonstrated expertise in life support system management, a track record with complex species collections, and in many cases completion of AZA professional development programs.

Open Water SCUBA Certification (PADI/NAUI) - required for exhibit diving and underwater maintenance duties.

CPR and First Aid Certification (AHA/Red Cross) - mandated for emergency response in aquatic work environments.

AZA Behavioral Husbandry Certificate (AZA-BH) - validates professional-level animal training and enrichment practice.

AZA Management and Operations Certificate (AZA-MO) - supports advancement into curatorial and supervisory roles.

The average Aquarist salary in the United States is $59,155 per year, based on the most recent data from Glassdoor.

Pay for this role shifts meaningfully based on institution type, with large public aquariums in major coastal markets offering higher compensation than smaller inland facilities. Years of experience with complex or high-profile species collections and holding AZA professional certifications are also among the stronger drivers of above-average earnings.

Quantify your animal care results where possible - note the number of species or specimens you managed, specimen mortality rates maintained, or water quality compliance records held over a defined period to give hiring managers concrete performance context.

Highlight technical competencies directly by name, including life support system types you have operated (filtration, UV sterilization, protein skimmers), husbandry database platforms such as ZIMS or TRACKS, and any SCUBA certifications held.

Demonstrate experience breadth by specifying the taxonomic range of your collection - listing marine fish, freshwater invertebrates, amphibians, and reptiles separately signals a versatile husbandry background that is more compelling than a generic "aquatic animals" summary.

Open with a specific example of an animal care challenge you solved - such as diagnosing and treating an outbreak of a common fish disease or restoring a life support system outside scheduled hours - to immediately establish your hands-on credibility with the hiring manager.

Connect your water quality management and husbandry record-keeping skills to the institution's AZA accreditation obligations, showing that you understand how your daily work contributes to the facility's compliance standing and long-term reputation.

Mirror the job posting's language around species groups, system types, and husbandry standards when describing your background, since aquarium applicant tracking systems are calibrated to flag exact terms like "closed aquatic systems" ,"SCUBA-certified", and "life support maintenance."

Aquarist is a rewarding but highly competitive career that suits candidates with a genuine commitment to animal welfare and the physical demands of the role. Hiring demand at established public aquariums is steady rather than rapidly expanding; the broader zoologists and wildlife biologists field, which includes this role, is projected to grow 2 percent from 2024 to 2034, with roughly 1,400 openings per year nationally, most from attrition rather than new positions.

An Aquarist specializes exclusively in aquatic and semi-aquatic species - fish, invertebrates, amphibians, and marine reptiles -and takes primary ownership of water chemistry, filtration systems, and SCUBA-based exhibit maintenance. A Zookeeper works across a broader range of terrestrial and semi-terrestrial animals, with responsibilities centered on enclosure upkeep and behavioral enrichment rather than life support system operation. In smaller institutions, one person may cover both functions.

The role demands juggling several distinct technical areas simultaneously - animal health monitoring, water chemistry, life support mechanics, exhibit fabrication, and accurate daily recordkeeping - all within a facility operating seven days a week. Irregular hours, physical labor including SCUBA diving and lifting heavy equipment, and the pressure of responding to animal emergencies outside normal shifts add to the difficulty, making consistency and attention to detail non-negotiable.

Public aquariums and zoological institutions employ the largest share of Aquarists, driven by the need for certified professionals to manage complex living collections and maintain AZA accreditation standards. Government and federal agencies, including NOAA and the U.S. Fish and Wildlife Service, rank second, with positions focused on research, conservation, and native species programs. Resort and entertainment venues with permanent aquatic exhibits represent a third concentration, particularly in hospitality markets where guest experience standards require consistent animal care staffing.

The hands-on core of this profession - specimen health assessment, behavioral observation, disease diagnosis, and emergency response - still depends on in-person judgment that automated systems cannot replicate, and that is unlikely to change in the near term. AI-assisted tools are beginning to take on data-intensive tasks such as automated water quality monitoring alerts, pattern detection in husbandry records, and predictive flagging of health anomalies before they become critical events. Aquarists who build fluency with these monitoring platforms, while deepening their expertise in complex species husbandry and life support system management, will be positioned to take on higher-value curatorial responsibilities as the technology handles more of the routine data layer.
