Frequently Asked Questions

Do I need to be a certified scuba diver to become an aquarist?

Yes, scuba diving certification is essential for most aquarist positions. Many facilities require at least a PADI Open Water certification, though some positions prefer advanced certifications. You'll spend significant time underwater cleaning exhibits, feeding animals, and performing maintenance. Some research-focused positions may require scientific diving certification through the American Academy of Underwater Sciences.

Can I become an aquarist without a college degree?

While possible, it's increasingly difficult. Most modern aquariums require at a minimum a bachelor's degree in marine biology, zoology, or a related field. However, you might start as a volunteer or in an animal care worker role without a degree, then pursue education while gaining experience. The competition for positions makes a degree nearly essential at reputable facilities.

What's the difference between an aquarist and a marine biologist?

Aquarists focus primarily on husbandry-caring for animals already in captivity at aquariums. Marine biologists typically conduct research on marine ecosystems, often studying wild populations through fieldwork and data analysis. Aquarists work mostly with captive animals in controlled environments, while marine biologists may spend time on research vessels or conducting field studies. Many aquarists hold degrees in marine biology, but they apply that knowledge to animal care rather than research.

How competitive is it to get hired as an aquarist?

Very competitive. Aquarist positions, especially at major public aquariums, receive many more qualified applicants than there are openings. Most successful aquarists start as volunteers or interns, sometimes for months or years, before securing paid positions. Flexibility in location, willingness to start in smaller facilities, and extensive volunteer experience significantly improve your chances. Be prepared for a lengthy job search and consider starting in related animal care positions.

Do aquarists only work with saltwater animals?

No, many aquariums feature both freshwater and saltwater exhibits. Aquarists may care for freshwater fish, amphibians, and aquatic reptiles alongside marine species. Some facilities specialize entirely in freshwater ecosystems. Your specific responsibilities depend on your facility's collection. Aquatic biologists working in freshwater research or river conservation represent another career pathway for those more interested in freshwater systems.

Can I work with specific animals like sharks or dolphins?

Possibly, but specialization typically comes with experience. Entry-level aquarists usually work with various species across multiple exhibits. As you gain experience and demonstrate competence, you may specialize in particular taxa. Working with marine mammals often requires additional training and certifications. Large aquariums with specialized exhibits offer more opportunities to focus on particular animal groups, but expect to spend years working with diverse species first.

Is aquarist work seasonal, or are there full-time positions?

Both exist. Major public aquariums typically offer full-time positions with benefits, though competition is fierce. Smaller facilities, seasonal attractions, or part-time positions are more common for entry-level aquarists. Some facilities increase staffing during busy tourist seasons. Many aquarists work part-time or seasonally while volunteering elsewhere to gain experience. Full-time positions become more available as you advance in your career.
